Do no fully trust the system for now because it has to be undergone acceptance from all over the world. Mind you to invest on it if it is already being regulated like the stock market exchange. For now, the system is on 50/50, it may be good or it may be bad depending on the government because whether we like it or not the government will take actions for a new system and if this is not being approved for sure it will be declare as illegal, scam and etc. and no one will going to like the system.
Cryptocurrencies is still in period of development lokee their regulations and security. This however, caused the system to be volatile and I think when it comes to obtaining profits, there are lots of ways to do it. In the future, I can say that it has bigger potential because of its advantages iver to Fiat system.
