So I would definitely be a user of such a service.
You are getting the whole idea behind this. There are millions of dollars in small change out of circulation, because a lot of
people are hoarding coins in bottles. Most of this change came from merchants giving people change, when they bought
something or paid for some service. My idea will get rid of those small change at the point of origin. .... We will never
replace cash, so I probably used the wrong word there... but we can turn those piggy banks coins into BTC, before they
are hoarded in a bottle.
You say it like it's so damn simple, but let's talk how it's going to look in reality.
I have just left 2$ at the airport, I'm taking my satoshi....and this is all I'm going to do with this method cause I'm not usually using cash, 99% I use a debit card.
And at the end of the year, because the price BTC has gone up 2x , I'll need to file a tax form for the income I've made and go pay taxes for the 2$ ....
In the end I'm going to get rid of the pain in the ass change to get triple pain from the IRS for 2$.
And you're going to have to declare all the profit you've made
2 cents when buying 0.000004 at 9000
1.06 cents when buying 00000003 at 8763
Sounds fun?
