Don't think of Ethereum as a cryptocurrency. Ethereum is more a crypto-solution to centralized web services rather than financial services.
Think of its token, ether, as fuel for ethereum processes.
Nope. The only thing it is is a money making train right now. Incredible volumes. The only thing folks are seeing is profit. People would trade a token whose only function would be to make your dachshund sing like Michael Bolton if it made them similar money.
Yeah but it's not because people see it like this that it IS a money ^^
Otherwise you can qualify crops of being a money. Its speculated amount is 36 times the real world supply.
