Paying in Thailand with Lightning - Paying direct to merchants on @BTC Map - Travala for flights and accommodation - @Bitrefill for groceries and fuel vouchers - @PlebQR for QR payments - 2fiat for card payments What else?
If you are so concerned about making bitcoin "legal" do you even ask yourself how fiat currency is legal despite being a tool to oppress people by stealing their time and energy through money printing? where is your moral compass?
