How are you going to send me a Silver Coin via the mail??? haha
Do you want a silver coin? You still haven't sent me any HEX! Isn't HEX worth a little more than a fiat non-silver dime?
A situation may be coming where I could walk to the local pawn shop, sell a dime or two for piles of cash and feed my family, no crypto could do that. Actually, crypto did do that, since I earned it and sold it for silver dimes. Had I kept is as crypto, I'd be very sad watching it loose it's value so quickly.
There's no denying that a connected world, where we can transact so quickly while being so far away is amazing, but that time may be passing us by as things begin to crumble. At some point, the only things of value are things that are in our hands. Could print a "paper wallet" and try to trade... but not everyone loves crypto, especially when people are scared.
Blockchain has it's strengths and it's weaknesses - it's strengths are self-evident... it's weaknesses are about to be discovered.
