now I try fixedfloat but 1% fees is too much, and I also don't understand when I exchange BTC why they charge 30 USD but I'm the one sending the BTC! ?
Are you asking for leverage or regular crypto trading?
You won't find any centralized exchange that is doing no-kyc fiat trading, but there are few more left with crypto only trading if you are willing to take the risk.
Poloniex, mexc, coinex and few others didn't have strict kyc last time I checked, but I see they also started to make changes because of new regulations.
There are good alternatives like PeachBitcoin, Bisq, Agoradesk, Exch, Robosats, etc. but do your own research.
