tard time aside.... houston we've got a fuking problem here, lol. look into the tech
Bro the "tech" is nothing "new", it's Apple/Samsung pay. Except it's "anonymous"

People have been paying without cash since the 1800s, when the local general store or tavern would let customers keep weekly tabs, then people used checks and credit cards. Real money is the backer behind these, as it is with Bitcoins. And like everything else someone will figure out a way to manipulate,hack,counterfeit, make it non secure over time.
And why weren't people concerned when a payment method fluctuated continually?
