OP can I know how many bitcoins you were sold because of that fall kf $500 in the bitcoin price.And you sating that bitcoin cash and ethereum will take over bitcoin but it will never happen so don't spread lies withour any analysis.
I think only that Ethereum has a chance, but not more than Bitcoin is just approaching Bitcoin's price. but I do not know when it will happen.
Ethereum does not care about decentralisation or immutability. This blockchain is totally worthless. And soon they are going to switch over to proof of stake with all this huge coin holders. LOL
Ethereum has a lot of issues and is in bed with politicians and incumbents of the actual financial system. Furthermore it is not clear if it will be declared as security or not. And the chances being declared or defined as security are pretty high despite all shilling by Andreesen and Horowitz. Expect many exchanges to drop the coin then.
So no Ethereum will never replace Bitcoin. I think it is more likely that it won't have much of relevance anymore in about 5 years. Furthermore there are a lot of strong Ethereum competitors, EOS, Stratis, Waves or NEO for instance, out there who will try to replace it from it's actual second place.
