You're not done with shit kike. Don't leave like a pussy. SHTF isn't what we have to worry about. Jew dollar domination isn't even started. Next year they are starting FEDNOW. It's literally a fully centralized digital coin. Your dumb ass will be the first singing up touting how great it is. SHTF is dumb as fuck. I already explained that do you. It's a distraction kikes like you use to keep us enslaved. YOU WANT WHITES ENSLAVED. Still, bitccoin works better than cash when SHTF as demonstrated in almost all recent wars and natural disasters. People won't even accept native currencies in many cases and in during the typhoon in the Phillipines the FUCKING ATMS OPERATE ON ELECTRICITY like everywhere else moron yet bitcoin kept on working. Motherfuckers couldn't even GET cash. As far as serial numbers on dollars, the point is if the banks want to they an recall YOUR money and when the store turns the dollars into the bank, the bank doesn't have to accept them. It's similar to what they do with counterfeit money. Physical dollars are paid for by the fed to the treasury(mint) with DIGITAL dollars dumb ass. You're just a distracting kike that will have us all hooked on FEDNOW next year because you can't stand that fact that some pimply teenager told you about bitcoin 5 years ago and you feel fucking stupid.
