Lmao. Who is going to let you buy a car not knowing how much the currency you are paying with is going to be worth by the time they cash it out? Or do you just pay an extra 25% to cover the spread just incase?
The blockchain has some great uses. Decentralized currency is not one of them.
And as far as doing business with me, I really doubt you could afford me, so there’s no worries there.
