In this cycle, market makers are too eager
Whether it's GPS, SHELL, or GUN, they all want to take advantage of the initial popularity after being listed on Binance to harvest some retail investors. These market makers are well aware that there are too many new altcoins and market attention shifts very quickly.
If they don't take advantage of the hype now, then once this opportunity is gone, it may not come back. In fact, if market makers can do harm, the project parties are certainly involved; it's just a two-person show.
