I want to transfer funds from my private wallet to CEX who don't need KYC, like KuCoin, Bybit, etc.. the amount isn't much around $300 and i want to use it for trading, trading on DEX is nowhere similar to trading on CEX. also i don't see myself withdrawing massive amounts of CEX anytime soon, so withdrawal won't be an issue too.
If you plan to stick to the smaller amounts then chances are that Kucoin won't ask you for KYC, just keep in mind that if you end up being successful at trading and end up with a lot of money, Kucoin will most likely ask you to go through KYC process.
I never want to withdraw to bank, want to earn online spend online on basic stuffs. Just want to move form private wallet to CEX for trading, i don't have BTC in private wallet only some altcoins
Another thing to keep in mind are withdrawal fees are those are not negligent at all, especially since you mentioned that you wanna use your crypto to pay for stuff. For example, both Kucoin and Bybit have 0.0005 BTC fee.
