I plan to start a new altcoin to be tied to something that has a reasonably lasting value like precious metals or fiat money.
I would appreciate getting other people's opinion on what must be assumed to be the greatest interest and need. A means of payment pegged to fiat money or savings item pegged precious metals?
There is nothing new about what you have just said, there are already lots of altcoins that are pegged to real currencies and the ones that are pegged to precious metals, so many of them more than you can count.
Those that are pegged with real currencies are the stable coins like the USDT, PAX, DAI, TUSD, and so many of them that I cant even count. Then as for precious metals, these are the ones I dont really know much about it, some people have said that they are fake and not really pegged to any precious metals, but there are already so many of them in the market: there is PAX Gold, which I know for sure is not fake because it is approved by the NYDFS.
There are a lot of so called gold backed currency but the problem is almost all of them don't actually holds the required amount of gold for escrow.
Anything which are not falling into the category of "cryptographically signable and verifiable" for these kind of project's reserve will lead to scam its investors. This is the reason why I would rather believe the projects which are being minted out of thin air than projects with gold reserve.
