I upvoted even before clicking the link. It's something that needs to be beaten into any one who wants to own crypto. There are some caveats... If you do not have full control over your keys, it's still not your crypto. This goes for any site that let's you type in your own keys via a web wallet. I mean yes, its better than custodial like Coinbase, but you need a better method using hardware wallet or multi-sig systems. Only then can you truly own your crypto.
