protip: Ethereum can be used by criminals too, not just Bitcoin. Though, I'm curious (not trolling), why is Ethereum's model a better way forward? Are you talking about smart contracts or what?
Bitcoin...is an impractical, user-unfriendly first mover. Ethereum is the flawed second mover (ok, I'm discounting all the silly coins in between). I'm honestly not sure who the ultimate winner is. Unless the Bitcoin or Ethereum community fundamentally changes, it likely won't be them.
I'm very excited for the space. Just not for the current currencies.

Bitcoin was the crypto of choice due to the network effect, although for now it is probably better to skip ethereum and skip right into somthings like XMR and Zcash.
