I don't really think this will happen. It is too ideal, to begin with.
I concur with this opinion and the majority of responses. We would like Bitcoin to become a global reserve asset replacing the USD, but if that happens it will take a long time. It has some intrinsic characteristics that could allow it to be so in the future, such as its deflationary nature, but as of today it is more a fantasy than a reality. Would states and central banks have to buy Bitcoin for their reserves as well, for that to happen, and that is not likely to happen in the near future. .
I saw news recently that major banks among 55 out of 100 have invested in blockchain and crypto companies, of course this is no longer just a fantasy but we have partially proven facts and we will soon see bitcoin becoming as the global reserve asset in the next few years .
