I think Ethereum has the potential of being so much bigger than Bitcoin. Remember - Bitcoin is a currency, and that's it. Sure, it's the first one,and it's a pretty good currency. It will (or is all ready) also serve as a safe haven/store of value (much like gold).
But Ethereum..it could potentially be "everything". It can be worth almost unlimited amount of money. It is IMO incredibly cheap. The value of platforms such as Etherum and IOTA and perhaps others could be worth incredible amounts. Some might fail. Perhaps it's IOTA and not Ethereum. Who knows. But please own some of all of them. It is just so incredibly cheap right now.
