Pulseboard exists because most "crypto news" content is optimized for clicks — price predictions, breathless headlines, and recycled press releases — rather than written for someone trying to actually understand what they're looking at before they act.

What we do differently

Every guide on this site starts from a specific, concrete question — what a wallet actually stores, how much of a portfolio to risk on one position, where a stablecoin's peg can fail — and works through the reasoning behind the answer instead of asserting a take and moving on. We don't publish price targets, "next big coin" picks, or trading signals, because that content can't be made honest: nobody can reliably predict short-term crypto prices, and pretending otherwise is how people get hurt.

How content gets published

Guides are researched, drafted, and edited before publishing, and checked against how the underlying technology and markets actually work rather than assumed. We update guides when something material changes rather than leaving them stale, and we'd rather publish fewer, careful guides than pad the site with thin ones.

How the site makes money

Pulseboard runs contextual display advertising through third-party ad networks. We do not accept payment from exchanges, wallet makers, or token projects to feature or favorably cover them, and we are not currently part of any affiliate program — see our Advertising & Editorial Disclosure for the current, always-up-to-date status of that.

Not financial advice

Nothing on this site is investment, trading, tax, or legal advice. Cryptocurrency is volatile and carries real risk of loss, including total loss. Content here is educational and reflects general principles, not a recommendation to buy, sell, or hold any specific asset. Always do your own research and consider talking to a licensed professional before making financial decisions.

What we're not

We're not a trading desk, a signals service, or a testing lab with accounts on every exchange — some sections of this site are still being built out, and guides are marked clearly as live or in production rather than padded with placeholder pages. If a topic isn't covered yet, it's because we haven't finished it properly.

A crypto wallet doesn't actually store your coins — it stores the keys that prove they're yours. That distinction is the single most important thing to understand before you touch crypto at all.

What a wallet actually holds

Your coins live on the blockchain itself, not inside an app on your phone. A wallet holds a private key: a piece of data that lets you sign transactions proving ownership of whatever address that key controls. Lose the key, and you lose the ability to move those coins — nobody can recover it for you, because there's no central account to reset.

Custodial vs. self-custody

Every wallet falls into one of two categories, and the difference matters more than the app's name or interface:

Neither option is universally "right." Keeping a small, active trading balance on a reputable exchange is reasonable. Holding savings you don't plan to touch is generally where self-custody starts to matter more, because it removes a third party's solvency from your risk equation entirely.

Hot wallets vs. cold wallets

Within self-custody, wallets are further split by whether the private key ever touches an internet-connected device:

• Hot wallet — a browser extension or phone app. Convenient for frequent use, but the key exists on a device that could be compromised by malware.
• Cold wallet — a dedicated hardware device that keeps the key offline and signs transactions without exposing it to the internet-connected computer. Slower to use, meaningfully more resistant to remote attacks.

See Cold Storage vs. Exchange Wallets for how to think about which fits your situation.

The seed phrase is the whole game

Setting one up safely, step by step

1. Download wallet software only from the official project website or your device's official app store — search results and ads are a common phishing vector for fake wallet apps.
2. Generate a new wallet and write down the seed phrase by hand, in order, before doing anything else.
3. Verify the phrase when the app asks you to re-enter it — this confirms you copied it correctly.
4. Send a small test amount first before moving significant funds, to confirm the address and process work as expected.
5. Store the written phrase somewhere a fire, flood, or single point of failure won't destroy it, and somewhere a stranger won't stumble on it.

Once you understand custody, the next practical question is usually how much to hold where — covered in Cold Storage vs. Exchange Wallets.

People often use "exchange" and "wallet" interchangeably when they're starting out, but they solve two different problems — one is a marketplace, the other is custody.

What an exchange actually is

An exchange is a trading venue: it matches buyers and sellers, converts between currencies, and — by default — holds the resulting balance in an account it controls on your behalf. Signing up for an exchange gets you a way to buy and sell. It doesn't, by itself, give you direct control of a private key.

What a wallet actually is

A wallet doesn't match trades or set prices. As covered in What Is a Crypto Wallet?, it manages the keys that prove ownership of funds on the blockchain itself. A self-custody wallet doesn't need an exchange's permission to exist or to move funds — it just needs the blockchain network.

Where the lines blur

Most exchanges now offer a built-in "wallet" view of your balance — this is still custodial; the exchange holds the keys regardless of what the interface calls it. Meanwhile, many self-custody wallets now embed swap features that route through outside liquidity sources, which can make them feel like a mini-exchange. The category names are a UI convenience; the question that actually matters is always the same: who holds the private key right now?

A simple mental model

Think of an exchange as a store and a self-custody wallet as your own safe. You use the store to buy something, then decide whether to leave it on the store's shelf (an exchange balance) or take it home (a self-custody wallet). Neither choice is wrong on its own — see Cold Storage vs Exchange Wallets for how to decide which fits a given amount.

The first purchase is usually where new buyers lose the most money to fees and avoidable mistakes — not to market volatility.

Compare the real cost, not just the advertised fee

A platform can advertise a low, flat transaction fee while quietly building a wide spread into its buy/sell price — meaning you pay more than the market rate before any fee is even applied. Before buying, check the actual price you're getting against a live reference price (like the board on this site) rather than trusting the fee line alone.

Verify the receiving address every time

Things to check before you buy

Common first-purchase mistakes

• Buying because of social media hype rather than understanding what you're buying — see How to Evaluate an Altcoin before buying anything outside the largest, most established assets.
• Skipping account security setup until "later" — set up two-factor authentication before you deposit any funds, not after.
• Not deciding in advance how much you're comfortable risking — see The 1% Rule even for a first purchase.

An honest breakdown of the trade-offs, for people holding more than "play money."

The core trade-off

Keeping funds on an exchange means trusting that exchange's solvency, security practices, and willingness to let you withdraw whenever you want. Keeping funds in cold storage means you alone are responsible for a seed phrase that, if lost, cannot be recovered by anyone. Neither removes risk — each just changes what kind of risk you're taking on.

What has actually gone wrong, historically

Exchanges have failed, been hacked, or frozen withdrawals before — sometimes due to external attacks, sometimes due to mismanagement of customer funds. This isn't a reason to avoid exchanges entirely (they're genuinely useful for trading and onboarding), but it is the reason the phrase "not your keys, not your coins" exists: funds on an exchange are a claim on that company, not a directly-held asset, until you withdraw them.

A simple framework

Cold storage isn't risk-free either

Self-custody trades counterparty risk for personal-responsibility risk: a lost seed phrase, a house fire that destroys your only backup, or a phishing site that tricks you into typing your seed phrase are all real, common failure modes — arguably more common than exchange failures for an average individual holder.

A reasonable middle ground

Many holders split funds across both: an exchange balance sized for what they're actively using, and a self-custody wallet for the rest, sometimes across more than one hardware device or backup location to avoid a single point of failure. There's no universally correct split — it depends on how much you hold, how technically comfortable you are, and how much you trust your own process for safeguarding a seed phrase.

Related

If you haven't yet, start with What Is a Crypto Wallet? for the fundamentals behind this decision.

Most losses individual holders report trace back to a scam, not a flaw in the blockchain itself. The patterns repeat often enough to be worth learning once.

The patterns that repeat, regardless of platform

• Unsolicited "support" contact — a message or call claiming to be from an exchange or wallet provider that you didn't initiate.
• Manufactured urgency — "your account will be locked," "act within 15 minutes" — pressure designed to short-circuit careful thinking.
• Requests framed as verification — being asked to "confirm" a wallet by entering a seed phrase, or to install remote-screen-sharing software.
• Offers that don't make economic sense — giveaways promising to send back more than you send, or guaranteed high returns with no real explanation of where the return comes from.
• Lookalike sites and apps — near-identical copies of a real exchange or wallet's login page or app listing.

The single rule that stops most of these

Before you click a link

Type known site addresses in manually, or use a saved bookmark, rather than clicking a link from a search ad, a direct message, or an email. Lookalike domains (a swapped letter, an extra word, a different top-level domain) are difficult to catch at a glance under time pressure — which is exactly the point.

If you think you've been scammed

Disconnect any wallet connections from the site involved immediately. If a seed phrase may have been exposed, move remaining funds to a brand-new wallet with a freshly generated seed phrase on a device you trust — don't reuse the compromised one. Report it to the platform and, where relevant, local authorities.

Not all two-factor authentication is equal — the method you choose changes what kind of attack it actually stops.

The three common options

Why SMS is the weakest common option

A SIM-swap attack tricks or bribes a phone carrier into moving your number to an attacker's device, which lets them receive your SMS codes directly. It requires more effort than most password-only attacks, but it's a well-documented technique specifically because SMS 2FA is so widely used as the only protection on financial accounts.

Authenticator apps are a solid default

An authenticator app generates a time-based code on your device itself, with nothing sent over the phone network — this closes the SIM-swap gap. It's a reasonable default for most accounts, including exchange accounts holding a moderate balance.

Hardware keys for meaningful balances

A hardware security key is the only common option that's resistant to a real-time fake login page, because it verifies the actual website's identity as part of the login process rather than just producing a code that could be typed into a lookalike site. For an account holding savings you'd be upset to lose, this extra step is generally worth the friction.

Most beginners spend all their time deciding what to buy and almost none deciding how much — which is backwards, because position size is the one variable that determines whether a single bad trade can actually hurt you.

The core formula

Position sizing based on a stop-loss (the price at which you'd exit a losing position) comes down to three numbers:

You can try this with your own numbers using the calculator on the homepage.

A worked example

Say you have a $5,000 portfolio and decide to risk 1% ($50) on a position. You plan to buy at $100 and exit if the price falls to $95 — a $5 price risk per unit. Dividing $50 by $5 gives a position size of 10 units, or $1,000 of exposure. Notice that the position size (20% of the portfolio in this example) came out of the math — it wasn't decided first.

Why this matters more than the entry itself

A trader who's right 40% of the time can still be profitable if losses are consistently small and wins are allowed to run — and a trader who's right 70% of the time can still blow up an account if one oversized position wipes out months of gains. Position sizing is what keeps a wrong call small enough to recover from.

Common mistakes

• Sizing based on conviction, not risk — "I'm really confident about this one" is exactly the thought pattern that precedes most oversized losses.
• Moving the stop-loss instead of accepting it — this converts a defined, small loss into an undefined, growing one.
• Ignoring correlation — five "different" altcoin positions that all move together during a market-wide drop function as one large position, not five small ones.

See The 1% Rule for how to pick a sensible risk percentage per position.

A simple sizing habit that keeps one bad week from becoming a bad year.

The rule

Risk no more than about 1% of your total portfolio value on any single position — meaning if the trade goes fully against you and hits your stop-loss, you lose roughly 1% of your total holdings, not the whole position.

Why 1%, specifically

At 1% risk per position, it takes a long, unlikely streak of consecutive losses to meaningfully damage a portfolio — the math is forgiving enough to survive being wrong repeatedly, which matters because being wrong repeatedly is normal, not a sign you're doing something wrong.

Try it

Use the quick calculator on the homepage to turn a risk percentage into an actual position size, or see the full math in Position Sizing 101.

The unglamorous habit that outperforms most trading strategies over a full cycle.

The problem with timing

Calling tops and bottoms consistently requires being right twice — when to exit and when to re-enter — and crypto's sharpest moves often happen in short, unpredictable bursts. Missing just a handful of the best days in a multi-year period can meaningfully reduce total returns compared to simply staying invested.

Dollar-cost averaging as an alternative

Buying a fixed dollar amount on a regular schedule, regardless of price, removes the need to guess short-term direction. You'll buy some at high prices and some at low prices, but you avoid the specific failure mode of putting a large lump sum in right before a downturn — or, just as commonly, sitting in cash the entire time waiting for a "better" entry that never feels safe enough to take.

The behavioral piece

Most timing mistakes aren't analytical failures — they're emotional ones: buying during euphoria (FOMO) and selling during panic (capitulation), which is the exact opposite of buying low and selling high. A fixed schedule, decided in advance, removes the in-the-moment decision entirely.

Crypto markets have historically moved in pronounced multi-year swings. Understanding the general pattern is useful — treating it as a predictive tool is where people get into trouble.

The general pattern, described loosely

Market analysts commonly describe a rough sequence: a quiet accumulation phase after a decline, a markup phase as prices rise and attract attention, a distribution phase where early participants sell into growing enthusiasm, and a markdown phase as the decline accelerates. This is a descriptive pattern drawn from looking backward at past cycles — it is not a law of nature, and no two cycles have unfolded identically.

What amplifies swings in crypto specifically

• Leverage and forced liquidations — when overleveraged positions get forcibly closed during a decline, that selling can accelerate the drop, and the reverse is true on the way up.
• Thinner markets than traditional assets — many crypto assets have less liquidity than major stocks, so the same dollar amount of buying or selling moves the price more.
• 24/7 trading with no circuit breakers — traditional markets pause trading during extreme moves; most crypto markets don't, which can let momentum build further before it exhausts itself.
• Narrative-driven sentiment — prices can move heavily on expectations and social sentiment well before (or without) any change in underlying usage.

A disciplined approach, regardless of where you think you are

Rather than trying to time entry and exit around a cycle, the approaches covered elsewhere on this site apply at any point in one: size positions so a wrong call doesn't do lasting damage (see The 1% Rule), and consider a regular buying schedule instead of trying to perfectly time a bottom (see Time in Market vs. Timing the Market).

Tax treatment of crypto varies a lot by country and changes as regulators catch up — this covers the concepts that show up in most jurisdictions, not specific filing instructions for yours.

What commonly counts as a taxable event

In many tax systems, several actions can trigger a taxable event even if you never converted crypto to your home currency:

• Selling crypto for fiat currency — the most obvious case.
• Trading one crypto asset for another — many jurisdictions treat this as disposing of the first asset, not a tax-free swap.
• Spending crypto on goods or services — often treated the same as selling it, then spending the proceeds.
• Earning crypto — through staking rewards, mining, or airdrops — which may be taxed as income when received, separately from any later gain or loss when you eventually sell it.

Why record-keeping matters more here than for typical investments

Unlike a brokerage account that issues a single consolidated statement, crypto activity is often spread across multiple exchanges, wallets, and on-chain transactions with no unified paper trail. Keeping your own records of dates, amounts, cost basis, and the purpose of each transaction as you go is far easier than reconstructing a year of activity later.

Cost basis, in plain terms

"Cost basis" is what you paid for an asset, used to calculate gain or loss when you dispose of it. When you've bought the same asset at different prices over time, jurisdictions typically require (or allow you to choose) a method for deciding which specific units you're considered to be selling — commonly first-in-first-out (the oldest units first) or a specific-identification method. The method you're allowed to use, and whether you can switch methods, depends on local rules.

A reasonable starting habit

Related

Good records start with understanding what you actually hold and where — see What Is a Crypto Wallet? if you're still getting the fundamentals down.

"I never sold it" doesn't automatically mean "I don't owe anything" in many tax systems — receiving new tokens can itself be a taxable event, separate from whatever happens when you eventually sell them.

Airdrops

An airdrop — tokens distributed to wallet addresses, often for free — is treated as taxable income in many jurisdictions at the fair market value of the tokens when you gain control of them, even though you paid nothing to receive them.

Staking rewards

Rewards earned from staking are commonly treated as income at the time you receive them, valued at their market price on that date. If you later sell the staked rewards, that sale can trigger a separate capital gain or loss calculated from that same value.

Hard forks

When a blockchain splits and holders of the original asset receive a new token as a result, some jurisdictions treat the new tokens as income upon receipt, similar to an airdrop, while others apply different rules depending on whether you had control over receiving them.

The common thread

Across all three, the practical lesson is the same: record the date and market value the moment you gain control of new tokens, not just when you eventually sell — reconstructing that value months or years later is far harder. See Crypto & Taxes: The Basics for the broader record-keeping framework.

A stablecoin is designed to hold a steady value, usually pegged to a currency like the US dollar — but "designed to" and "guaranteed to" are very different claims, and the gap between them is where the risk lives.

The three main types

Why "stable" isn't the same as "risk-free"

A prominent algorithmic stablecoin collapsed in 2022, losing its peg entirely within days and erasing billions of dollars of value along with a connected token. It's a widely-cited example precisely because it showed that a stablecoin's price chart looking flat for a long time says nothing about whether its underlying mechanism can survive a genuine stress event.

Where the risk actually hides

• Collateral quality — reserves in short-term government debt behave very differently under stress than reserves in less liquid or riskier assets.
• Redemption access — a peg backed by real, redeemable reserves is structurally different from a peg held up purely by market confidence.
• Custodian and counterparty risk — even fully-backed reserves depend on the bank or custodian holding them remaining solvent and accessible.
• Smart contract risk — for crypto-collateralized and algorithmic designs, a bug in the code that maintains the peg is a separate failure mode from the collateral itself.

Why people use them anyway

Despite the risks above, stablecoins solve a real problem: moving value between exchanges or DeFi platforms without converting back to fiat currency each time, and giving traders a way to sit "in cash" within the crypto ecosystem. The reasonable takeaway isn't to avoid them, but to treat the choice of which stablecoin to hold, and how much, as a real risk decision rather than an assumption that "stable" means "safe."

Related

The same custody questions from Cold Storage vs Exchange Wallets apply just as much to where you hold stablecoins.

Decentralized finance replaces a bank or broker's role with code — which removes some kinds of counterparty risk and introduces others.

The core idea: smart contracts instead of intermediaries

A DeFi protocol is a set of smart contracts — self-executing code on a blockchain — that handles lending, trading, or other financial functions without a company approving each transaction. Instead of a bank deciding whether to accept your deposit, the contract's rules do, automatically and identically for everyone.

Lending and borrowing protocols

You can supply an asset to a lending protocol to earn yield paid by borrowers, or borrow against collateral you've deposited. Because there's no credit check possible on an anonymous blockchain address, borrowing is typically over-collateralized — you deposit more value than you borrow. If your collateral's value falls too close to your loan amount, the protocol can automatically liquidate (sell) it to protect lenders, often with a penalty.

Liquidity pools and automated market makers

Instead of matching individual buyers and sellers like an exchange order book, many DeFi trading protocols use a pool of two assets supplied by other users, with a formula that adjusts the price as the pool's balance shifts. Suppliers earn a share of trading fees, but can experience "impermanent loss" — ending up with a less valuable mix of assets than if they'd simply held them separately, if the assets' relative price moves significantly while funds sit in the pool.

Many DeFi protocols rely on stablecoins for pricing and collateral — see Stablecoins Explained for the risks specific to those assets.

A rising price chart tells you what already happened, not why it happened or whether it continues. These are the questions worth answering before the chart, not after.

Start with what problem it claims to solve

Can you explain, in one plain sentence, what the project actually does and why it needs its own token to do it? If the honest answer is "the price is going up," that's not a project thesis — it's a description of the chart you're trying to evaluate independently of.

Check token distribution and unlock schedule

A large share of tokens held by the founding team or early investors, especially with a large unlock scheduled soon, can create sustained sell pressure regardless of how the underlying product is doing — the people who received tokens cheapest are often the first able to sell.

Look at actual usage, not just social activity

Social media follower counts and posting volume are easy to inflate and don't measure whether anyone is actually using the underlying product. Where available, on-chain activity, active addresses, or real transaction volume are harder to fake and more informative.

Understand the token's actual utility in the protocol

Some tokens are structurally required for the system to function — paying for transactions, participating in required governance, or serving as collateral. Others exist mainly as a claim on future value with no functional role today. Neither is automatically disqualifying, but they carry very different risk profiles.
