Investing and trading are the best way to make a huge income or profit with bitcoin. That what experts or well experienced persons are saying on ways they earn bitcoins. It is really a good way to make profit. As for me, my current plan is to just keep my earnings with bitcoin until I reached my desired amount. After that, I will be spending all the excess to it and maybe convert it into cash and try to invest on stocks, mutual funds and the like. Maybe buy some valuables for my family.
