I don’t see how it makes sense economically as opposed to just putting all fiat you don’t need to spend into bitcoin each month. That way you don’t have to pay capital gains and would actually end up with more bitcoin in the end because you don’t have the make another sale to pay the tax when it comes due, which then would count for another capital gain for the following year. Not to mention paying more tax to the government is exactly what many of us are trying not to do.
