haha! well, those mandatory things like gravities don't count since you have to do it you like it or not in many countries.

Crypto coins do count. Well, it's a tough one as a long term investment since the market fluctuates regularly. It seems not easy to profit with a new type of coins now. I wish I had bought a few BitCoins when those were first released. Also, there are those who invest in currencies and the Forex market.
