Read the post properly, and you'll understand what OP is talking about. To cut a long story short, weak hands need to liquidate their positions (preferably below the point they got in) to allow the market to grow further afterwards, and for that to happen we need crashes and corrections every now and then. In other words, whether a crash has been initiated artificially, or due to the market being overbought, it is a very healthy occurrence helping the market forward in the long run. This way, the bottom after each next crash will always be higher than the previous bottom, and this trend is something we have experienced consistently throughout the years. Great and spot on observation by OP.
It's a case of there always needing to be a fresh supply of people who are willing to buy at a higher price and less people who are willing to sell at a higher price. If we still had the majority of people who got in to bitcoin at under 1 cent then they would almost certainly be willing to sell at the current price, at least a large portion of their holding. We need those bitcoin to be moved to someone who is willing to pay a higher price and will want more before they sell.
