if it does lowering prices then it just constitute with some kind of retracement or market correction. Because what happen is that price will be manipulated so that it will create fear again and investors won't buy. But instead price will rally again, once the price is too high or premium enough, then those who bought on lower prices is expected of course to take their profits.
With that large amount taken from the market, price will drop. And if the buying volume cannot compensate with the selling pressure, then price going lower will be expected. But otherwise until it hasn't happened yet, you should be expecting higher prices on bitcoin.
The people's negative thinking can cause the price to decline. We experience some corrections from time to time but I don't think it was the reason. It may be because some people are enjoying their gains now. Manipulations are always there but people can grow and same people won't fall on that trap again.
This makes the price rally instead of dumped, although even if we experienced a dumped, the price can still recover because manipulators and some regular individuals are buying during it. The situation we have right now is bullish and can continue like this for quite a long time. Those who invest early and continue hodling are lucky.
