Which risks matter most in crypto?
Most people worry about the price. Most permanent losses in crypto come from somewhere else.
A lost recovery phrase, a fake support account, an exchange that stopped paying out. The price can recover; those usually can't.
Four kinds of risk
Price swings get the headlines, but custody, scams and project failures cause many permanent losses. Each one has a part you control.
Price risk is the obvious one, meaning large swings and long drawdowns, covered in the volatility lesson.
Custody risk comes from where coins are held. Exchanges have collapsed and frozen customer funds, and self-custody brings the risk of losing your own keys.
Scams and fraud take many forms, including fake giveaways, impersonated support staff, rug pulls where creators drain a token's funds, and phishing sites that copy real ones.
Project risk is slower. Many coins lose their community, developers or liquidity and drift toward zero, and regulation can change what's allowed where you live.
A quick check before you buy
Ask five questions. Who controls the project and can they change the rules? How much supply is still to unlock? How easy is it to sell? Where will I keep it? What would a 90% fall do to me?
If you can't answer one of them, that's the risk to look into first.
Risks you control and risks you don't
You can't control the market, a project's developers or a regulator. You can control where your coins are held, how much you put in, whether you borrow, and whether you click links in messages.
Most permanent losses come from the second group, which is good news, because they're the ones you can do something about.
Platform failures, with dates
Some of the largest losses in crypto came from platforms failing, not from prices. In each case customers held a claim on the platform rather than coins in their own control.
Custody risk isn't theoretical. In February 2014 Mt. Gox, then the largest bitcoin exchange, halted withdrawals and filed for bankruptcy after losing hundreds of thousands of bitcoin. Customers waited about a decade for partial repayments to begin. In early 2019 the Canadian exchange QuadrigaCX collapsed after its founder died, with customers unable to reach their funds.
2022 brought a cluster. Terra's UST stablecoin lost its peg in May, wiping out tens of billions of dollars of value across UST and its sister token LUNA. Celsius, a crypto lender that promised high yields, froze withdrawals in June and filed for bankruptcy in July. In November, FTX, one of the largest exchanges in the world, stopped processing withdrawals and filed for bankruptcy within days, and its founder was later convicted of fraud.
The common thread is that customers held a promise, not coins. A platform can look busy, well funded and endorsed by famous names right up to the week it stops paying. Spreading holdings, withdrawing what you don't need to trade, and being wary of yields that look too high reduce how much of your money depends on any single promise.
How risks stack
Risks multiply along a chain. Three steps that each look safe give about a 1 in 10 chance that something goes wrong, using these example numbers.
Each extra step between you and your coins adds its own chance of failure, and those chances multiply. Take an example where you buy a token on an exchange, bridge it to another chain and deposit it in a lending app. Give each step an illustrative chance of getting through a year without a serious problem, say 98% for the exchange, 97% for the bridge and 95% for the lending app.
The chance that all three survive is 0.98 times 0.97 times 0.95, about 90.3%. So the chance that at least one fails is roughly 9.7%, much higher than any single step's risk suggests. Add a second bridge or a yield vault on top and the odds slip further. These are example numbers, not real ratings, but the multiplication is the point.
Before chasing an extra percent of yield, count the layers, meaning every exchange, bridge, smart contract, wrapped token and company your money passes through. Then ask whether the reward pays for the added chance of losing the lot. Often the simplest setup, with the fewest parties, carries the least risk you can't see.
Key terms
Rug pull
Creators abandon a project and take its funds.
Counterparty risk
Depending on a company or person to keep a promise.
Smart contract risk
Losses from bugs or exploits in code.
Regulatory risk
Rules changing what's allowed or how it's taxed.
Rank and promises are poor safety checks
How safe a coin is. Rank shows size today, not safety. Large coins have collapsed before.
What a guarantee is worth. Guaranteed returns in crypto are a warning sign, not a feature.
What people get wrong
A high rank isn't a safety rating. Large coins have failed before.
Guaranteed returns are a warning sign, not a feature.
Why it matters
Most permanent losses in crypto come from these risks rather than ordinary price moves.
Common questions
How do I check if a site is real?
Type the address yourself or use a saved bookmark, and be wary of links in messages, ads and search results.
Does KryptoKap give investment advice?
No. KryptoKap shows market data and explains how it works. It doesn't recommend what to buy or sell.
Are my coins insured on a crypto exchange?
Usually not in the way a bank deposit is. In the US, FDIC insurance covers cash in bank accounts, not crypto, and some exchanges' private insurance covers only certain hacks of their own systems. Read the exchange's terms, and assume that if it fails your coins become a claim in bankruptcy.
Can a stablecoin lose its peg?
Yes. Terra's UST collapsed in May 2022, and even well-backed stablecoins have briefly traded below $1 during stress, as USDC did in March 2023 when some of its reserves were held at the failed Silicon Valley Bank. Backing, transparency and redemption rules decide how quickly a peg can recover.
Why do scams target crypto so often?
Transactions are fast, hard to reverse and can cross borders in minutes, so stolen funds are difficult to recover. Many newcomers are also unfamiliar with how wallets and signatures work, which makes fake support staff, giveaways and copied sites more convincing than they would be elsewhere.
