Centralized cryptocurrencies will take Bitcoin over, sooner or later. Sad, but impossible to stop them. Just look at the first 200 coins and see that more than 50% of them are centralized. I predict Bitcoin falling to 2nd place on the Market later this year or during the spring or summer of 2018.. and then people will take money out of it. We'll see what SegWit will bring us. If Bitcoin falls, prepare for a historic move: BTC going down to the 2nd place.. I am not sure if ETH will be the coin to replace it, but I'm more than sure that some coin will..
