From what I am observing, it was JPMorgan and other huge institutions that started to become very interested in Bitcoin. Let me just remind you that a few years ago JPMorgan officially called Bitcoin fraud. It seems that under the new circumstances, such institutions are setting the sail to go with the wind, and if not today, I'm sure that the Bitcoin price will explode within a few weeks. However, I am afraid that in the coming days there may be price manipulation and exceeding the $50k level will not be so easy.
Most institutional investors have had to think again after realizing their folly and underestimation of Bitcoin and cryptocurrency and now as a couple have began to make a turn back, it's only a matter of time rivalry would ensue and that would be the velocity of escape for Bitcoin. Breaching the $50,000 mark is only a matter of time, it's sure to happen though when is what one can not tell because it's a psychological level that would not be readily taken off.
