Ethereum is a distrubuted JVM basically? Guess its alright if you wanna run a casino that can't get taken down, otherwise I dont know what kind of uses you can find for this thing.
Except much much more limited and every line of code costs way more money to run on one computer while only acting as if it was ran on a single computer in practice.
Thats exactly why I mentioned an application such as a casino - the vm will provide guarantee of a payout. People will pay for that, but they won't pay for you to run 3D games on the thing.
