BlockFi may be transparent, but they've changed their rates for everything besides stablecoins to almost nothing, and those changes were mostly from one day to another. Their interest is also paid monthly which sucks and they have penalties and such things, looking at their ToS alone should be enough to︀ not use them.
Crypto.com has $700M insurance which covers things like theft, which is nice,︁ but not really relevant unless the money stolen is just a fraction of the assets︂ being held by them. It's still a good platform though and I have nothing against︃ them.
Binance should be above Crypto.com though, they're the biggest platform, have their own crypto︄ (crypto.com too but it's not as big and as used as bnb) which is the︅ second one by market cap and they handle over 60-70% of all the volume in︆ crypto. Yes, they have been hacked, but each time users were compensated and issues were︇ fixed, which makes the platform stronger against future attacks.
Celsius should also be above BlockFi︈ as they're trying to comply with every state in the US and everywhere they operate.︉ If they're not sure it's legal, they don't do it, such as letting US users︊ use their CEL tokens as they may be considered securities by the SEC, but as︋ they're not sure, they don't allow it. The founder is a known person for his︌ work in Tech, they do weekly AMA's and they're transparent about their investments, earnings, and︍ such things. They've, for example, announced that they've invested $500M into crypto mining. Diversifying user︎ funds should also create a more secure and stable way to earn income for the️ company and therefore its users.
Edit:
As the user above said, Nexo does also have some sketchy things going on and I've read about the sketchy founder activities.
Also, he's right about crypto.com, they're spending a lot on marketing, but I'm pretty sure they've been able to do that with their platforms earnings and their token.
