i think i prefer to use the money to directly buy bitcoin because if you decide to mining bitcoin then you need to thinking about many things like how much your electricity cost in daily or monthly, what kind of hardware you want to use, the hardware needs to be maintain and we need to take care our hardware so it will work properly. the big important question is the electricity because this is the main thing that we must use to start mining so if you can not determine how much the price you should pay then you might not makes a good profit in the end.
