My only concern with BlockFi is hearing about the hack last year where customer data/details were leaked which is the risk I guess of going through KYC. Especially after Ledger's leak, I have changed my tune a little bit towards lending platforms. Yes, the yield and income from it is nice to have but BTC is appreciating in value a lot over the last 10 years. Is getting an extra 4-6% worth that risk?
I guess it depends on your risk/reward profile but if it's working for you then that's great! Hope you reach your goals :)
