all rapid grows in a market must have rapid lowering of price, action = reaction
but i agree, this time it is more value gains than speculation, it will be lowered but no to 500$ range or 700$ range but maybe to 800$ only

This time crash was created not by market collapsing under pressure of but rather was created by bad news of imminent bitcoin ban/harsh regulations issued by China.
We have no idea where this pump would end (I assume we would reach new ATH this time) if it wasn't abruptly ended by exaggerated rumors.
