In reality we can't make any predictions about any altcoins or coin whether it is Bitcoin of eth or edr .
Because any instant of time fluctuation with big pump and dump may arise in any altcoins so here it is totally waste to make predictions for such a long times of year .
Since it is clear that the future of ETH more better than any other altcoins because per month users of ETH are increasing reapidly like the users in the Bitcoin , So here more and more chance for the ETH to grow like Bitcoin .
