Have you ever encountered a situation where a coin suddenly doubles or triples in value within a few days, only to plummet again without any clear reason? That is exactly the pump and dump phenomenon I want to share today, as it is one of the most common market manipulation strategies that investors need to know to protect themselves.

In the cryptocurrency market, pump refers to the sudden price increase of a coin caused by a coordinated effort of a group of investors. They will buy a large amount of the coin when the price is low, then spread positive information on forums and social media to stimulate FOMO among new investors. When the price has risen to a certain level, those executing this strategy will start selling off (dump) to realize huge profits, causing the price to drop sharply and leaving late investors with heavy losses.

I clearly remember the case of Tierion (TNT) in 2020. This coin had a small market cap and was little known, but suddenly its price jumped from $0.05 to $0.11 in just a few days. However, after 10 days, the price fell back to $0.03, even lower than the initial level. When I looked into it carefully, there was no significant news about the project, only positive rumors on Facebook. That is a typical example of pump and dump.

So why does this phenomenon happen so frequently? First, because sharks (large investors holding significant capital) have the ability to manipulate market psychology. Second, the legal regulations in the cryptocurrency field are still loose, unlike traditional stock markets. Third, ICOs and new projects emerging create great opportunities for sharks to carry out their pump and dump plans.

The operation process usually goes like this: step one is accumulating assets when the price is low, step two is pumping and maintaining the price by creating fake comments and positive predictions, step three is dumping to sell off and take profits. Very simple but extremely effective.

How to recognize if a pump and dump strategy is underway? Pay attention to sudden price increases over a short period, especially if it’s a little-known coin. If it suddenly gets mentioned a lot on tech forums or by celebrities, that’s a warning sign. Information from reputable news outlets should also be carefully examined.

Now, how to avoid falling into a pump and dump trap? I have some advice based on my experience. First, always research the project thoroughly before investing—learn about the team, real-world applications, and strategic partners. Second, limit emotional influence from the crowd—remember there are always many other opportunities. Third, manage risks carefully by determining appropriate capital allocation and planning your trades in detail beforehand. Fourth, prioritize investing in large-cap coins with reputable teams and long-standing operational histories.

There is one very important thing I want to emphasize: understanding pump and dump is not to encourage participation in it, but to protect yourself. This strategy poses significant risks and negatively impacts the stability of the entire market. By conducting thorough research, managing risks effectively, and avoiding being swept up in herd mentality, you can participate in cryptocurrency investing more safely and effectively.
