These platforms are good if you're really into staking and you know which is good and bad. But, I wouldn't let my funds go into it for a longer time and I'll choose coins that I can stake through its own native wallet or a wallet that's trustworthy. Just like putting it alone in a Ledger Nano wallet such as Tezos and Algorand. By the way, thanks for the information you've shared. Especially in nexo, I was searching about inputs about it.
