Wondering how many of you earn interest on your Bitcoin?
I do not think this is necessary, it is obvious with increase in bitcoin price.
Do you feel this is risky, whoever owns the private key owns the BTC ?
Who owns the seed phrase or the private key owns the bitcoin, it is not risky if you think bitcoin network can fail, never think of that because bitcoin network is stronger than anything you can compare it with. What you should be careful about are hackers and scammers generally.
