Do not use Gate.io if you are a US citizen. Actually, if you don’t use a VPN and fess up that you’re a US citizen, you’ll be blocked from opening an account.
If you use a VPN to sneak through and start a new account, then send some tokens to your Gate.io account, trying to send those tokens from Gate.io to another wallet will run afoul of KYC requirements. And once you KYC and if they find out you’re American, your tokens will be locked in the account. And once you try to send some tokens, they’ll endlessly have pop ups telling you to go through KYC.
If you’re Canadian or elsewhere, you probably won’t have these issues.
