I see you're a person heading into the Future... Seems to me, there are those who seek total control over us... Those who want to know our every move... Where we eat, where we sleep... There will be a "LIST" of everything we do, and guess what...??? They'll be checking it twice.. lol...

You really wouldn't need to carry that much coinage... Just 3 Quarters, 1 Dime, 2 Nickels and 5 pennies would be the same as you carrying around a Hundred Dollars in Paper (Debt) Notes...

I do like Crypto's... I'm sure they'll change the World... But I can't depend on them, in the same way I can depend on our Coinage... Coinage will be for the day to day Medium of Exchange...

I tend to see Paper and Digital Trade Dollars in our Future, for larger transactions... I also see us Replacing the Federal Reserve Notes with our own Paper Dollars, which shall be backed by U.S. Coinage...
The Paper and Digital Dollars, being meant for larger transactions...

Anyway... I like the privacy of using Cash... One will still be able to Deposit their Cash at the Bank to Store, or to use it Digitally through Debit or Credit Cards... Or use it to buy and use any Crypto you choose...
