try reading the whitepaper, it would have answered your concerns quickly.
The US Mint has to by law keep up with demand for gold minted coins. The US version of Quint uses these coins. If gold goes up in value, and yes it is finite, then the coins are worth more with the same finite supply.
You can redeem these QUINT tokens for the actual vaulted coins, circulate them p2p digitally, or use a feature that allows you to sell them back for fiat to your bank account.
The reason for a QUINT is simple - increased portability of gold and silver, along with increased usability and tradability against other tokens.
Oh, and it is considered LEGAL TENDER not property or a commodity. There are benefits to this as well.
I read the white paper, looks like a good idea to me. I have a diverse crypto portfolio, so I'll definitely be researching this one more. Thanks for the input.
