Not right to be maximalists, build "Muslim" stripe that works with bitcoin/lightning and other currencies even fiat. Eventually Fiat will die out when crypto proves itself to be the better option which has no bureaucracies or hidden fees, etc.

The market will always choose the one best currency alone. And so will I.
Islam and reason allows for free trade and market not controlled and maximalist communist/western fake free trade that forces a currency or controlled market. Gold, silver,bronze, goods, etc and the new Bitcoin and similar currencies will be there too and probably prevalent because of the advancement of humanity's lifestyle with electronics and such.
