Pump and dump
A group buys an asset that's barely traded, creates a buzz and then sells to the buyers it lured in. The losses are borne by those who come last.
You pick a small asset with little trading. Because so little is going on, even small purchases push the price up sharply.
Then comes the attention phase: posts on social networks, chat groups, supposed insider information, screenshots of gains. The most convincing argument is the rising price itself, because it's real.
As soon as enough new buyers have arrived, the organizers sell. The price falls as fast as it rose, often within minutes. Left behind are those who got in last. Anyone who puts $100 into a coin that has just risen 300 percent often has only $20 an hour later.
It's also written pump-and-dump or abbreviated P&D, always meaning the same scheme. How to spot it: normally there's hardly any trading, then the price suddenly rises without any news. On top of that, time pressure and calls to act fast before it's too late. Real opportunities aren't in a hurry.
How easily an asset can be manipulated depends on how little it's traded. If market depth is low, even a little volume moves the price a lot. It falls just as sharply when the organizers sell. Their profit is the difference between the price when buying and when selling, minus how much they move the price with their own buying and selling.
The process exploits well known weaknesses in thinking. What you read constantly, you take to be true. If seemingly everyone is excited, you want to be part of it. And the fear of missing out weighs more than the fear of losing (loss aversion). The rising price looks like proof that the story is true and strengthens confirmation bias.
With shares, market manipulation is illegal and prosecuted, even if that's laborious for small stocks. With cryptocurrencies comparable supervision is often missing entirely, which is why it happens there more often and more openly. The practical conclusion: stay away from very small, thinly traded assets as a rule.
Summary
- The precondition is an asset that's barely traded. Low volume is the warning sign.
- The rising price is advertising, not proof.
- Urgency in the messaging is always a red flag.
