Go buy a hotdog on the street shop and pay him with paypal
LOL, now yes i got your point. bt why do we still use cash for larger transactions?
I personally don't know many people that use Cash for "large" purposes. Cash still has some advantages over BTC atm, for example it is much easier to transact in cash when you do not have access to an internet connection.
Another advantage of cash it it's relative anonymity as it generally cannot be traced and it is nearly impossible to determine who had/spent what exact dollar bill
I am glad you saying nearly impossible.
I know law enforcement use "micro dot" technology to mark money, and serial numbers on bills etc.. to track "dirty" money. But as for tracking it, from mint to let's say 2 years use... yea I grant you that it's nearly impossible.
I think we will have fiat cash with us for many more years... Some people still trade in cattle in 3rd world countries, and they had "cash" for years.
Merchant adoption, would determine, how fast fiat cash would dissapear. {Imagine years from now, when people will say... "Do you remmember, when we still used cash, to pay for stuff"
