How is it possible
With all that has been said about virtual currencies, how is it possible that people are gullible enough to fork over real money in order to "invest" in funny money.
If you're dealing in nonsense money, you do not sell shares, you give a mining program and tell people to download it and run it. That is the only form of investment that is required.
Anything else and you should just call the cops and keep 'em talking.
