Price is almost doubled since the beginning of this year, what you are saying that price will be tripled until the half of this year. To me that sounds like a "hard to happen" prediction, normally not impossible, with bitcoin price anything can happen in very short period.
Lets wait to break $6k barrier, which can happen or not, if we break it I think we will go more higher, if price stops around here maybe we will see some little down trend and price dropping. Its up for weeks, my logic tells me to be careful now.
