This is very simple to realize that BTC will become the most significant exchange rate crypto at the end of 2018. Because the BTC exchange rate is currently the highest in the market and far beyond Ethererum at the price of just more than 400 dollars. In the next 5 years. BTC and ETH will become the symbol of the cryptocurrency market.
I agree on you that in the next 5 years Btc and ETH will be different from its current price and all cryptocurrency will be affected as well. The only question is who will still there and who will be a dead project some of them made promises. Well atleast we are all engage on blockchain adoption.
