Ethereums only actual real use case thus far has been issuing ICO's. Billions worth of ICO tokens have been deployed by Ethereum's smart contracts.
Now imagine what would happen if governments really banned ICO's... I don't see how Ethereum wouldn't suffer from a massive crash.
Bitcoin would probably be fine, except the same idiots as always that sell at any headlines containing ban+crypto/bitcoin would also dump, but it would quickly recover. Ethereum... not so much.
Let's hope this was it for Bitcoin and we are going back to $5000 now, double bottomed and it's going up. Hopefully not heads and shoulders formation with further drop, that would suck.
It is good thing that we need to think on , i do agree because first the ethereum is the base of all this kind of ICO and more ICO's started to exploding by using ethereum platform and talinking about bitcoins i think we are ready this december for $5000 i have a strong feeling that it will be as this month.
