if it goes parabolic for too long, then I feel it makes take longer to recover in the longer term after the correction. This kind of dip or down, makes me think we have not see an all time high yet, and that the price has a higher floor.
Its true if it goes to parabolic, it will take enough time to recover.On the other hands it can increase the number of buyer. People may start buying more BTC and hold them long for sure. But can give no profit to Seller. On my point of view it can decrease the number of sellers because nobody want to lose money.
