Gambling: bitstars, mbit, betcoin and others.
Do you consider gambling an investment? In our reality, this is just a way to lose your money. After all, you will not be allowed to win, because it will be at a loss to them.
Gambling isn't a viable form of investment,but we do not always lose money through it,its also possible to earn via gambling,it just happens to a risky form
I wouldn't also in any way advice anyone to engage in gambling,rather it's best to trade effectively in the cryptocurrency market
