I started using Blockfi to earn interest on my crypto holdings a couple months ago and have been impressed with the site so far. Since I've joined the site has waived withdrawal fees for up to 3 withdrawals per month, removed minimum balance requirement to earn interest, and raised the interest rate. For those who don't know Blockfi provides loans to users backed by cryptocurrency with the option to be either a maker or a taker of the loan. They are affiliated with Gemini in some shape or form which is likely a good sign as Gemini is licensed in New York and touts better insurance and security than nearly any other exchange. I will write up a more thorough review eventually, but for now I just wanted to post my referral code for any new users looking to sign up.
