The Chinese are alive to the fact that escaped the silver bugs in the West, that you can derive a silver income from your pile of silver by covered short selling, even while retaining physical control of your silver hoard.
That's not income, just money you aren't losing. Besides, if silver decides to go up, then you lose your pile being short.
Yes, Bitcoin is on a meteoric rise relative to everything else; even with an instantaneous revaluation of the monetary precious metals, the cryptocurrency will outperform. This is not an issue of contention. However, Bitcoin still has at least a year or two before it is widespread enough to realistically be a direct competitor for contemporary currencies in the sense that it might be used for daily purchases and transactions.
I hope this reference to "contemporary currency" is not a reference to gold/silver. "at least a year or two before they're as widespread as dollars" is not a reason to prefer PMs over bitcoin. So why mention "contemporary currencies", and really, what's more contemporary than bitcoin?
If "might be used in daily contemporary life" is the value judgement, then PMs are completely ruled out, not even possibly an alternative. Maybe in an apocalyptic doomsday scenario, but certainly not a daily contemporary one.
