I wouldn't say zero! Also, moving forward things like planetary resources could challenge the stability of gold, but it's still pretty good and fairly liquid. For me, it proved more liquid than bitcoin; Exchanging bitcoin took 3 days coinbase + ACH; I liquidated a gold piece in an afternoon, could have gotten cash, but mailed a check into my bank and had the funds in 2 days (still faster than bitcoin, even with the USPS in the way)
These days spending old banknotes is problematic, even if they're in perfect condition.
Some people love gold, some people hate it, but everyone agrees it's the only thing that really has zero counterparty risk.
