Sharing insider information with newcomers.
Almost all meme cryptocurrencies have a market maker. In more or less non-meme cases, this is 100% of the time. The task of any market maker is to sell at the top and buy at the bottom, thus taking money on futures. They have a large amount of coins to manipulate the price, in rare cases all the coins that belong to the project team. The project team is always in contact with the market maker and before releasing good news, they always prefer to get rid of passengers, as any passenger is a competitor wanting to sell for more. The better the project, the more professional the market maker. Futures in cryptocurrencies roughly exist to take money from those wishing to get rich quickly. To lower the price, the project team just needs to remain silent for several months, and the price will drop by itself. Most new coins that are actively promoted at the moment are created by exchanges, and the largest part of new coins is stamped in a conveyor manner by top aggregators in the cryptocurrency space and added there to the list. The latter create for "one shot", so that if a pump occurs, they sell these junk coins to naive guys. The goal for everyone is to take money from retail investors. All these outflows or inflows of coins to exchanges in most cases are also manipulation. As it is possible to send more coins to the exchange than needed before the listing and after the listing, simulate that the coins are often withdrawn from the exchange, thereby prompting naive people to buy.
