I use Gemini, and I remember getting solicited for gemini earn many times. Since I was only buying and removing bitcoin, it was irrelevant to me, but I do remember that there was a lag time of possibly a few days to access any coins you deposited in the earn program. I believe Genesis was labeled as a partner. Gemini has a very cozy relationship with New York regulators,which may be why they seem to be avoiding scrutiny so far.
