I’d advice you use a non-custodial wallet to store your coins so you have full ownership of your coins and use decentralized exchanges.
I wouldn't advice crypto newbies to use Decentralized exchanges; it's more complicated and the chances of them getting scammed/ losing coins is higher compared to Centralized exchanges. How many of us on this board uses DEx exchanges? There are too many loopholes on DEX exchanges - scams are not moderated.
Self custodian wallets for storage and CEX exchanges for trading should be a newbie starter pack.
Yeah you have a point. Although a newbie who wants to maintain privacy may want to avoid exchanges that require KYC. I think in that case it’s better if he just uses p2p on remitano where he can buy crypto without doing a complete kyc.
