But the point is that you can do far more good by sending the money to some of the people who need it most, those in the lowest economic positions.
Rather than effectively sending it to the "average" Bitcoin user, which is definitely not in the lowest economic position -- and whatever the average Bitcoin holder spends on charity, it's only a small percent.
This is why Bill Gates spends his money on the Gates Foundation where it's designed to help those who need it most, rather than lighting all his money on fire so that the deflationary impact will help everyone in proportion to their savings.
