OTOH, this could be as well achieved by adding PM in your portfolio. But that's not our subject.
Surely you recognize the great disadvantages of gold as I explained upthread? No one could refute my question about who they will sell their gold to when all the gold dealers have been shut down as they are now in France, and recently extending to Belgium, etc..
There is no economy-of-scale in trading gold. But crypto trades at a distance and (not for Bitcoin) anonymously, thus economies-of-scale are easily attained.
It is no contest. Gold is dead forever. Fuhgeddaboudit.
FWIW, I agree that anonymity can be achieved -under certain circumstances- with BTC but, let me add, this is possible also by using almost any means of transaction. If one wants to be anonymous, he will do what's necessary to achieve so.
When the mining refuses transactions without KYC, then you will not be anonymous in Bitcoin. I have already explained how this will come about over time.
You are digging your expropriation grave with Bitcoin.
