Why people lose money on a scheme with "no risk"
Arbitrage is called risk-free because you do not guess market direction. That is true — of exactly one kind of risk. The rest are still there, and they are what drains beginners.
Below is the full list of what can actually go wrong, and what to do about each. No scare stories: every risk has a concrete action that reduces it.
1. Execution risk: the route only half closed
The most common and most underestimated. You bought the coin and did not manage to sell it — the price moved. Now you do not have arbitrage, you have an ordinary position exposed to the market.
What to do: keep balances on both venues in advance and close both sides simultaneously. Move transfers to afterwards — they should restore positions, not be part of the trade.
2. Transfer risk: the coin did not arrive
Wrong network and the coins are gone. Forgotten MEMO and the transfer hangs. Suspended withdrawals and the money is locked for an unknown period.
What to do: check the network twice, copy addresses with the button, and before trading confirm in transfers that withdrawals and deposits are open. Make your first transfer to a new exchange a minimum test amount.
3. Venue risk
While coins sit on an exchange, the exchange controls them. Withdrawals can be paused and accounts can go under review.
What to do: keep what you need for working, not everything. Turn on two-factor authentication. Do not leave large sums on small venues longer than the route needs.
4. Liquidation risk on the futures leg
This applies to funding. Spot cannot be liquidated, a short can: a sharp rise plus thin margin and the exchange closes it. You are left holding one leg of the scheme.
What to do: no leverage, keep spare margin, watch the liquidation price. On a unified account remember collateral is shared.
5. Counterparty risk on P2P
You are dealing with a person. They can disappear after you mark a payment, or send a fake screenshot.
What to do: check the merchant trade count and completion rate. Release coins only once the money is visible in your banking app. Never move the deal into private messages. More in the guide to scam patterns.
6. Banking risk
Frequent identical transfers from different individuals look suspicious to a bank, and an account can be frozen pending review.
What to do: never mention crypto in a payment reference, pay only from accounts in your own name, do not ramp up volumes abruptly.
7. Smart contract risk
This applies to DEX work. Some tokens can be bought but not sold. Some pools have their liquidity withdrawn.
What to do: only work with tokens that at least one centralised exchange accepts, and verify the contract address rather than the name.
Three rules that cover most losses
- The first-trade rule. Walk any new scheme, exchange or network with a minimal amount first. The goal of the first operation is to complete the path, not to earn.
- The one-basket rule. Do not keep all your capital on one venue in one scheme, however well it works.
- The record rule. Keep a table: spent, received, fees, result. After ten operations you will see your real return rather than the expected one.
How much to keep working
A practical benchmark: arbitrage uses money whose loss would not change your life. That is not a figure of speech — a venue can suspend withdrawals and a transfer can go astray.
And separately: do not borrow to fund arbitrage. The scheme pays 1–3% per operation, not a guaranteed return by a deadline. One stuck route and you are paying loan interest out of pocket.
Frequently asked
Which risk bites most in practice? Execution and transfers. That is where people actually lose, not on exotic scenarios.
Should I keep everything in USDT? For arbitrage yes, it is the working currency. But remember it is a token issued by a private company, not a dollar in a bank.
How do I know a route is too good? A spread above 10% almost always means suspended withdrawals, a dead pair or a fifty-dollar offer.
