Crypto 101 Daily

A “pump and dump” is one of the oldest tricks in finance, and crypto has given it a turbocharged new life. If you’ve ever seen a little-known coin suddenly rocket up while people scream that it’s “going to the moon,” you may have been watching one in progress. Here’s how the scheme works and how to avoid being the one left holding the loss.

What a pump and dump is

A pump and dump is a scheme where people artificially inflate the price of an asset (the “pump”) through hype and coordinated buying, then sell their holdings at the peak (the “dump”), causing the price to crash and leaving later buyers with heavy losses. The organisers profit; almost everyone else loses.

It works best on small, cheap, obscure coins, because their prices are easy to move and easy to hype — and because new, excited buyers are easy to attract.

How the scheme plays out

The typical pattern: organisers quietly buy a low-value coin cheaply. Then they aggressively promote it — social media hype, “urgent” tips, fake excitement, sometimes paid influencers — to lure in a wave of buyers. As those buyers pile in, the price shoots up, which attracts even more people afraid of missing out. At the peak, the organisers sell everything. The price collapses, and the latecomers — who bought high on the hype — are left with coins worth a fraction of what they paid.

Why beginners get caught

These schemes are engineered to exploit exactly the emotions a beginner feels. The rapidly rising price looks like proof it’s a winner. The urgency (“buy now before it’s too late!”) short-circuits careful thinking. And the social proof of lots of excited people makes it feel safe. By the time it “feels” like a sure thing, you’re usually near the top — which is precisely when the organisers are about to sell to you.

How to protect yourself

The defences are refreshingly simple. Be deeply suspicious of any coin rising fast on hype, urgency, and influencer noise rather than real substance — that combination is the classic signature. Never buy something just because it’s “mooning” or because you’re afraid of missing out; that fear is the bait. Avoid acting on anonymous “tips” or coordinated group buys, which are often the scheme itself. Stick mainly to established coins as a beginner, and remember: if you don’t understand why something is going up, you have no idea when it’ll come down. This is education, not financial advice.

Key takeaways

A pump and dump inflates a coin’s price through hype and coordinated buying, then the organisers sell at the peak, crashing it and leaving latecomers with losses. It targets small, obscure coins and exploits FOMO, urgency, and social proof. Protect yourself by distrusting fast hype-driven rises, never buying out of fear of missing out, ignoring anonymous tips and group pumps, and favouring established coins. If you can’t explain the rise, stay away. This is education, not financial advice.
