Most of the most famous, I would say. Less well-known exchanges, every third allows trading without KYC. По моей статистике, если вы возьмёте 80 бирж, то 33 из них не требуют обязательной верификации.


In very rare cases, it is prohibited to trade with leverage; I have come across 1 or 2 such exchanges out of 100. The worst exchange offered only a $5,000 limit per day for unverified users, and the best 200 BTC per day. Now ask the question, are there many people in the crypto world who have daily volumes of more than $5,000? Even the minimum limits are enough to satisfy the needs of 90% of crypto users, because 90% of crypto users use small amounts, since they do not have a lot of money. If a trader passes verification and the exchange allows him to withdraw $5,000,000 instead of the $5,000 daily limit, he will no longer have money from this and he will not become richer.


If you do not hold funds on the exchange, but only go to the platform to exchange one cryptocurrency for another and then leave, then you do not need these examples of the collapses of FTX and MtGox, because this only affected those who stored their funds there. Using centralized exchanges is one thing, but storing your money in custodial wallets is a completely different matter. For some reason, the community believes that since you use a centralized exchange, you will definitely store your cryptocurrency there. Such logical chains are beyond my understanding.
