I know is manipulation about how dropping price bitcoin or altcoin, but I am still little worried if many people keep sell their coin, I know they have panic to sell coin and make price more drop, just few people know is bad situation to make altcoin or bitcoin go down to drop price.
In the market when a price drop occur due to a manipulation probably there is more possibility that to recover the price it might take more time than a normal recover because like you have mentioned when many people starts to sell there tokens the market will be over load with currencies so more selling than buying can cause huge price crash most of the time
