Me and Sid Blumenthal.
A gold-backed currency is an excellent idea, sez goldbux. Add a reliable website front-end to create accounts & make payments, with strong encryption. Then you have a real alternative to debauched fiat currencies.
Bitcoin's blockchain has some merit, but is not backed by hard assets.
e-gold (19982015) (RIP) had the right structure, but failed to raise sufficient seed capital, then made the mistake of chasing micro-payments for trivial online transactions, and ran afoul of the Feds. Douglas Jackson is still reinventing an alternative currency, but his business model is too awkward.
