I just realized that many new people entering crypto still don't fully understand the pump and dump phenomenon. Today, I will share this because it is really important when you trade.

Basically, a pump is when a large group of investors, called "whales," start buying a huge amount of a coin when the price is still very low. They quietly accumulate, without anyone noticing. Then, they begin to spread rumors, post positive articles on forums, Facebook, Telegram to stimulate FOMO among newcomers. Everyone sees the price rising sharply over a few days, everyone fears missing out, so they rush in to buy. That is exactly when the pump is happening.

The problem is, after the price rises high, these "whales" immediately sell off — unload everything they bought. That is called a dump. When they sell out, the price drops straight down, even below the initial level. Late buyers get stuck holding assets at a lower price, or are forced to cut losses to reduce damage.

Let me give a specific example. In 2020, the coin Tierion (TNT) — an obscure altcoin — suddenly increased by 45% from $0.05 to $0.11 in May. But just 10 days later, the price plummeted to $0.03, even lower than at the start. When I looked into it, there was no significant news about the project, only a few positive rumors on Facebook. That’s a classic pump and dump scheme.

Why is pump easier to happen? First, those holding large amounts of money can easily manipulate the psychology of small investors. Second, FOMO is a strong feeling — when everyone sees others making money, everyone wants to jump in. Third, the crypto market still lacks strict legal regulations, unlike the stock market. Fourth, ICO activities create great opportunities for bad actors to pump prices.

How to recognize if a pump is happening? Pay attention if the price of a coin suddenly increases abnormally within a few hours or days. Check if there is any news from reputable media, or if it’s just rumors on social media. If an obscure coin suddenly gets mentioned by a celebrity or becomes a hot topic on forums, be cautious.

I have some tips to avoid pump and dump traps. First, always research the project thoroughly before investing — understand the team, real-world applications, strategic partners. Second, don’t let herd mentality influence your decisions. There are plenty of other coins to choose from, no need to chase what’s hot. Third, manage risks — determine appropriate capital allocation and make a detailed plan. Fourth, focus on large-cap coins with high market capitalization, trustworthy teams, and long-term track records.

Overall, understanding pump and dump is essential for anyone involved in crypto. It not only poses risks to investors but also affects the stability of the entire market. By doing thorough research, managing risks well, and avoiding herd mentality, you can protect your assets and trade more safely.
