I definitely think it's possible, so many ERC20 tokens currently in Top 100 based on Market Cap.
That was so impossible to happen ethereum is also great cryptocurrency and i believe it is 2nd of the bes cryptocurrency and ethereum is the best altcoin but ethereum has still no chance to reach the bitcoin value because bitcoin is too strong and i know that the value of bitcoin is we will rise more but i think ethereum can hit $4000 by the end of 2018.
