Scammers have been fleecing people since the invention of money, and every new generation of technology sees scammers taking full advantage.

And bitcoin, in particular, is a scammer’s dream for several reasons:

Very few people really understand it. This makes it easier to make false promises and unusual moves without getting caught. It’s mostly anonymous. It’s a lot easier for scammers to cover their tracks.

Once bitcoin or other cryptocurrencies have been stolen, they are probably never coming back to their rightful owners.
It’s largely unregulated. There are ways for scammers to steal bitcoin without breaking the law, and there are few authorities that will ever go after them.
