Huh? crypto price is based on supply/demand of the crypto
simplistic version: not enough crypto … it's price goes up
so, if the price (not quantity) of your gold backed crypto rises - who shovels in the extra gold to cover?
… or if it's solely fixed-conversion-to-gold
how is your crypto,

possibly crackable by future computing power
better then ummm, gold backed gold certificates?
