because i don't wanna get in this situation again , and i checked "Guarda" i think its good one , do you know if they will ask for my identity if i use let ?
Use a wallet which private key is in your own possession. You don't give control of your private key to anyone else. It's like you are asking bank to have your crypto. If you are in bitcoin then Electrum is the best if you don't want to use the full node of course. Make sure you keep your seed safe, not in a digital format.
When you will send crypto to exchange, don't send large amount. Better if you use mixer which will break connection. Send the mixed coins to the exchange. There are also decentralized exchanges where you will never need KYC.
