IMHO you can trust all of them except maybe Nexo - they are shady. I had bad experience with celsius, they support reply in 72h , and that is ages in crypto. But they are legit. I lost on crypto.com because I was greedy and stupid to chose to earn in their own currency, MCO, which lost value so much that all my interest rewards were lost - learn hard way double lesson there - NEVER lock your coins at any platform - if you cannot withdraw in 24h you can lose alot. And never get rewards in platform currencies - only in kind or in stable coins (if they offer that option). Blockfi.com is very nice, their platform sometimes throttle but works. Pity they offer just 8 coins. I am big fan of apyharvest.com way of work - they do all with personal crypto bankers, on email, and reply and process requests always in less than 12h (in my case 4h average). Rates are perfect, referral rewards too and I trust them 100%.
