Selling high is one of the oldest forms of market manipulation, which involves artificially inflating the price of an asset through coordinated buying (selling high) and then selling it off after the price has risen (selling out). This type of behavior is usually initiated by a group of traders or social media KOLs who hype up low liquidity tokens in private chat groups or on social media to entice retail investors to buy. Once the price rises, the manipulators sell off their holdings, leaving later investors to pick up the slack and take the losses.
