If you spend bitcoin for stock of @COLDCARD @Foundation @SeedSigner @BitBox etc and people paid that bitcoin. But also some people buy these devices with fiat, which is directly converted into bitcoin. But after taxes and stock capacity holding you are nett losing bitcoin. Are you doing something positive for bitcoin? Some say you should take a fiat loan, because running it on bitcoin doesn’t make sense. But we’re using bitcoin fully, so what is better?
