Do you feel this is risky, whoever owns the private key owns the BTC ?
Also any resources for a high interest rate I think around 6% is the highest, these are some I have seen Liquity, Blockbank, Voyager, Nexo
thanks!
It depends on the platform you are using, use one that has a good reputation and trusted company like Crypto.com. I have some few btc in that site earning some interest for just holding and so far its going smooth for some months now, but as I said still risky to join in a platform you have no control over your keys so always DYOR before entering and educate yourself first.
