It the trendline will be broken, Bitcoin will most likely rise towards the $10k psychological resistance in a relatively short period of time. This is a very strong level, where price might start to consolidate. But if this resistance is broken, next upside target will most likely be the 88.6% Fibs, that is $18k area.
From that price a strong correction is very likely to take place and considering the average Bitcoin correction during an uptrend, BTC /USD should fall by 40%, towards the $10-11k , which is the 38.2% Fibs level.
This might be the time when institutional investors will step in, resulting in a strong growth of Bitcoin , the target for that wave could be the 161.8% Fibs, that is $30k area. Break above the $30-36k price, should confirm a very strong momentum for the Bitcoin in the long-term.
Anything could happen though, Bakkt, Nasdaq, ETF or any other catalysts could make the current price action deviate from history, and it will go a lot faster than before.
