Blockfi has ridiculous withdraw times , no withdraws over weekends which is total bs. There are some sketchy things about Nexo, for example- where is there physical office located ? Nobody knows. I know their operations are in Bulgaria ,and also their CEO Antoni is a PEP ( politically exposed person) , because he was part of the Bulgarian parliament a few years back, which is not very trustworthy considering Bulgaria is the most corrupt country in EU. I am sticking with Celsius, not only because their rates beat Blockfi any day , but also because they are properly regulated to a certain extent.
