In fact, you said that gold is the superior option short-term
But that's a minor transgression, really. The much bigger one is that gold is not good even for long-term investment or holding (call it what you like) for nation states unless you control the world gold trade (read, can set prices as you see fit). And it is definitely not Russia which controls it. Buying gold is a poor man's choice, only at a national level. Russia is freezing their resources in gold which means losing time and opportunity
Okay, let me reclarify my position. I never once mentioned anything about gold or Bitcoin as an investment
It is six of one and half a dozen of the other
You can call it as you please (investments, reserves, holdings, possessions, diversifications, etc), it doesn't matter. Gold is just bad for the purposes mentioned simply because your overhead costs involving short-term diversifying will outweigh any potential benefits. And I'm not even sure that actual ordering, processing documents and physical delivery of all these tonnes of gold won't take longer than the timelines you keep in mind ("in the span of less than a year")
All in all, the whole comparison is meaningless since no one buys gold to hold it for less than a year. There are gold derivatives created exactly for that purpose (i.e. options and futures)
