For now, my plan is only keep collecting and earning bitcoins from my services. For the future, i want to open a business about bitcoin related in my area.
I agree, the best way to spend your hard earned profit from your investments is to invest the excess money to other business or assets. In my case I prefer establishing passive income and investing land properties because its value is not diminishing but increases over the time, I think that would be the best way to spend your bitcoins too.
