I would handle Robinhood with great care, or more like a plutonium core... Well, honestly, I would just stay far away given their beyond shady history, and exploitative behaviour such as front-running their users being built into the system (reason for the "zero fee"). That being said, I have no idea about how their crypto solution is working, but I assume they're up to no good.
