Well, bitcoin can hit that level for sure. I’m still with bitcoin and I know he can survive on this, give 2-3months and the price of it is surely pumping hard, its a matter of time but we will arrive on this level safely.
$40,000 for this year is for sure? Nah, I don't think it's going to happen. We are still far from that price and bitcoin needs to pump that much first before saying that it's possible to see it @ $40,000.
in my opinion, bitcoin by the end of 2018 can and it is possible to reach $ 50K
Too high prediction, I'm trying to be optimistic but these prices are really high IMHO.
