I don't think that BTC will ever replace USD, because people are looking at BTC as an alternative asset. Why? I have already talked about it on a post recently I should quote it here for you:
But some people wanted to save the erosion of their funds..................
The moral of the story is, that people don't want to leave USD but also don't want to accept it fully, they want to diversify their portfolio so that they can not be manipulated. And can minimize the risk involved.
Hmm, For that I won't answer you and quote any proof the time will justify that and it will bring up the potential reasons why people were supporting this narrative with Bitcoin. I'm pretty confident because at least we need a universal currency in every age, as it was Gold before USD was replaced and now Bitcoin will How and Why for that a small hint for you is...
As the blunder we did before cant be repeated under the influence of any upcoming Superpower.. At least this is what I expect. I did check out your post but the narrative with the replacement of the USD is not for the store of value it is going to be our need. Needs cant be replaced with alternatives they must be fulfilled.
The point you are talking about is completely another approach, I do consider most of the investors are jumping into the market with similar intentions profit booking avoiding inflation, and blah blah, but at the end of the day, they need to recognize its main power with regulatory support and recognize that why they really need it. You are going to see the glimpses of this narrative in coming few months..
