Cryptocurrency is, in many ways, especially useful for fraud. It's relatively anonymous, which makes transactions between individuals more difficult to track. It's unregulated, so there are fewer safeguards against fraud. It's complex, so scammers are able to prey on more people who don't fully understand it. And it's unprotected, in the sense that consumers usually have no recourse in the event that they are scammed.

Can traditional financial instruments (like cash, securities or commodities) be used for fraud? Absolutely. But it's not as easy.
