I currently hold these coins--BTC, ETH, LTC, XMR, and ZEC.
I tend to agree with what most of you guys are saying. There is a real risk of losing my coins if I lend it out.
I am lending it to blockchain.com and it is giving me good interest. I think to lend is good on the site as we hold bitcoin on that site too. In this case we can earn additional money by lending to the site with same risk. If I lose the fund for lending then still I can lose my fund without lending.
I wasn't aware that blockchain.com wallet has started offering staking services or paying interest on our coins. I completely agree with you that if you keeping your money in an online wallet which already offers interest or staking then it is worth getting the most out of it because if they are going to run away you would already lose all you have there so why not earn extra in case they don't and if one wallet I trust online its going to be blockchain.com (which earlier was blockchain.info)
Personally I am not into staking or earning interest on my coins because its just too risky to hand over your coins to someone you don't know and the nature of crypto doesn't help either because the one who has the key is the owner the moment you send it.
