I get my bitcoin from a trusted trader and then I use that for some investments to make more from it instead of them just sitting idle doing nothing for me.
it seems you are buying your bitcoin. What are the investments have you done? I hope you don't invest in HYIP, or cloudmining because they are known just to eat up investment. Better to study trading and sportsbetting. This will at least give good amount of money / bitcoin if you master this kind of game.
