My question to the community is how much you trust these platforms to hold your crypto safe and don't scam away? Is the 4-6% annual interest rate worth the risk for you?
Depends on the circumstances.
Products like BlockFi I'd be comfortable with putting a chunk of my coinage in because of the fact that they are quite established, but I do believe that you should always be prepared to hand over KYC documents before actually subscribing to these investments.
BNB and other staking coins are risk-free technically because everything is decentralised - of course, they are prone to adverse movements in token price still.
6% per annum isn't something that is unachievable, but should raise alarm bells if it's not put out by a legitimate company with a track record.
