This makes the crypto markets very fertile grounds for both sophisticated wholesale manipulation and simple scams that would never be tolerated in "regulated" security markets.
One of the simplest and most popular scams is the "pump and dump". For example:
The pump --- A famous, wealthy entrepreneur announces with much fanfare that he has just purchased a large quantity of bitcoin. This enourages naive "investors" to purchase too driving the price up 20%.
The dump --- Famous wealthy entrepreneur then sells his large quantity of bitcoin and realizes a 20% gain.
If famous wealthy entrepreneur did this in a "regulated" market, he would find himself in legal trouble.
If you don't understand how these scams work, _you_ are most likely one of the people being scammed.
