Bitcoin has a massive lead over every other Crypto currency out there... it's backed by huge hashing power and a gigantic merchant network accepting it as a payment option. I cannot see why people
would shift to something, even more complex than Bitcoin. They should concentrate on being the best solution for Smart contracts, and not try to compete for the top spot for being a currency too.
The aggressive marketing and hype are driving this whole Eth thing... and once this dies down, and people realize what happened.... a whole bunch of people are going to be disappointed.
