There is a lot of institutional money going onto Ethereum with the hope that Ethereum smart contracts will save businesses a lot of money in streamlined backroom processes. I own BTC and ETH and plan to stay diversified, but certainly ETH has made me a lot more money. My only concern about ETH is that the number of ETH that can be issued is unlimited as far as I can tell, while Bitcoin is limited to 21 million. The law of supply and demand says that when supply goes up, the price will go down due to less scarcity. But as long as speculators flow in, the law of supply and demand doesn't mean much. Just my two cents worth.
