The most common use of bitcoin for me is this servers as a tool for us the be an investors. Because in the real investment world we all know that we need a lot of money just the buy a share. But here in bitcoin a small amount of money can be consider. But like in the real investment world the profit is always depending on your capital. So the big capital or investment you will put in the big profit you will also have. Also what good in bitcoin is you can used this to buy some stuffs online. In this modern day that shopping can be thru online. Bitcoin were been incorporated with that system. There are a lot of online stores that accept bitcoin as a way of payment.
