i want some advise from the expert because im only basis on my prediction can anyone tell !
Well it is a very hard advice to give because one may not know the possible outcome of the market which could either be negative or positive. I strongly believe that you should follow your mind on which one to follow. So many experts have already predict a positive direction even more than $25,000 increase in Bitcoin before end of December this year but is up to you to decide.
It can, but not this year, 2018 is year of crypto doubts. Many causes it and didn't trust it. Who knows by next year, so keep holding.
