There is actually functionally very little difference between Bitcoin and the rest of crypto. They are, at the end of the day, they're just algorithms that set a certain protocol for behavior. So I don't think that there's actually that much difference. The biggest challenge that you have in Ethereum is that it is, again, relatively slow and relatively high cost at this point. It has significant flaws, and ultimately I'm somewhat skeptical about whether it will end up winning or not.
