The interesting thing is encouraging. But we're even earning if the value of bitcoin goes up.
Go with your interest but security is what matters most for someone like me. I don't think that exchanges will even give you a refund if they are hacked unless they are generous like Binance.
The idea behind the exchange having your back is still a "grey" area in my opinion. They may be able to refund some users funds to 100% but what about the high $ accounts, they'll probably get partial refunds. Those with partial refunds will be given the nicehash treatment where they're still paying users and most still have not recovered 100% of their funds. I'm still behind the 'not your keys, not your coins' principle like what @btc_angela said earlier. For example Binance.us USD deposits are eligible for FDIC insurance coverage as of 2019.
