These numbers are really awesome and yeah millionaires are the ones driving BTC this time but if we look at this whole scenario from another angle, an angle of inflation which is telling us, there is more money in the hands of people which was lesser back in time, why? because of inflation. As inflation caused people to have more money so they have millions in BTC, I don't think we should see it as a great victory but a small one maybe.
Overall, those who have not invested 1 million but a little less have already crossed the 1 million target and are added to this chart as a number. People are becoming rich on BTC, I am seeing those achievements all over social media. BTC has outperformed its potential but still a lot to go. By the way thanks for using the term "Wholecoiners" as I did not know its meaning is those who have 1 BTC.
