I can understand what yimou say, but remember that Bitcoins are unconfiscated, but they could be stolen from you. On the other hand, if you hold gold, it is effectively yours, but in addition to being stolen, it can also be confiscated.

So yes, Bitcoins are yours, but even gold and diamonds could be truly yours, but every type of strategic reserve has its weak point.

Surely, nowadays, Bitcoin is one of the safest methods to create a strategic reserve.
