That won't surprise me at all.
BTC was heavily pumped for several weeks in a row without any apparent reason, no significant changes, nothing to justify the tremendous price rise.
Therefore, a sudden dump is to be expected...
Yeah, there are several things that affected bitcoin price due to the level where it was in the past, from market correction to over-congestion on bitcoin network - Too many users that leads to jamming the bitcoin network which causes paying high transaction fees and experiencing very slow transaction speed. Yet, bitcoin managed to survive the recent market correction and once the lightning network is implemented over bitcoin network, bitcoin will be faster and smoother than ever.
