ASKLEO: which platform to Earn Interest on Bitcoin do you recommend and why?

I've been presenting a friend of mine with some info on crypto in general and specifics. We got to a chapter of HODLing and how people can hodl while earning interest on your bitcoin put in a smart contract.

But the question appeared - which platform, DeFi or CeFi, would you recommend to use.

APY is not everything

Apart from the interest to be made, there are other factors that need to be considered before trusting your cash. These are: 1. Security, 2. Hidden features, 3. Tax information reporting,

What are your experiences with these platforms? Which one would you recommend? Do you think it is worthwhile or the transaction fees are going to eat up whole income?

IMHO the platforms I know they differ so much that you can't make your decision based on APR/APY only. I think that Nexo sounds pretty safe (EU based, insurance) but it also goes with KYC and tax reporting. I know we all need to pay our taxes, but the situation in Poland is not totally clear. I think the crypto should be taxed when exchanged into fiats. However in some interpretations, the authorities require to pay tax on legal transactions on every single crypto transaction [SIC!].

Which platforms I know:

• Binance,
• Nexo,
• BlockFi,
• Crypto.com,
