Bitcoin will be replaced by ethereum 
That is funny.
I know ethereum is doing good but there is much it must go on for it to take over the position of bitcoin.
I got some ethereum and I cant even withdraw it as cash. That is one problem.
How about exchanges. They prefer bitcoin over ethereum when ot comes to buying altcoin or just simple USD.
What do you think of Bitcoin Cash? It has simple set up and it can do a hard fork to adopt SegWit if it is more advantages?
