If Bitcoin is to be adopted as a medium of exchange, along with store of value and unit of account, then we need to use it as such. Important is that you take in more bitcoin that you spend, aka create value so you are gaining in reserves... I know the tax issue comes up, but zooming out there is a solution to the tax issue which I can elaborate on if anyone is interested... Regardless, live in the new paradigm, and visit the old as needed until it is no more.
