They are legit 100% . Same like Celsius and Blockfi.

I am using them since may 2019, when they were closed to Northern Ireland customers and some parts of UK only (could not access them if I did not use UK ip)

They do all they work via email, but they replay in 4h average in my case, never longer than 10h - which is superb. I wait for last celsius support email reply for 72h straight...

I have all my conversations with their crypto bankers from start, which is also neat to compare what I hold, earn an did in all this period.

If you need referral code, send me direct message, I do not want to share it publicly.
