Yes. I know it's a surprise inclusion.

Cryptocurrencies are volatile and you can leverage on that or just flip it. You buy from users who don't want to go through the exchange stress. You buy at a price you make decent profit when selling.

Many still see gambling as a luck thing but I see it as a steady way to make money when you put everything in place.

The difference between these 2 and the remaining 8 is you lose time and burn data which is another form of money.
