I often observe certain phenomena, and here is a summary of what it's all about.

When the price is pushed up to a certain level, they start claiming it's the bottom. Twitter accounts with 20,000 followers look very popular. But if you look deeper, you'll find there's a well-established system behind it. Open major platforms, and marketing accounts are everywhere—some accounts are actually operated by the same group of people using multiple small accounts, sometimes thousands or more. The goal is simple: create a false sense of hype, lure retail investors to buy in, and then sharply cut the prices.

During bear markets, these accounts are the most active, shouting every day that a bull market is imminent. For example, during a certain rally, when the price rose from 3,000 and only increased slightly, marketing accounts immediately started posting to promote it. But within a couple of days, the price began to fall. There are even more outrageous cases—once, an account with 100,000 followers issued buy signals, claiming that 94 was the top and the price could rise to 120,000. But what happened? The price kept dropping to 85,000, and those who believed in it lost everything.

I specifically asked friends in the trading community, and they confirmed this—almost every exchange and platform software has thousands of such marketing accounts active. Their pump-and-dump tactics have formed a complete industry chain. So, when trading, be extra cautious of these high-profile accounts shouting buy or sell signals, especially those sudden popular accounts.
