It's true what you say but they (Blackrock) don't have a lot to say in the matter. People will use Bitcoin more and fiat less and they know it. Fiat will not be gone ( not in a hundred years) but the scale will shift so drastically that we will not recognize it. Saylor is our friend for NOW , it works for both sides, he provides free advertisement and we get BTC more worth (if you think fiat). No one can predict the future. As always, one should use its own brain and be situationally aware. One major thing I agree with is what Jack Dorsey said "You want something to thrive (tech or whatever) Use it!" We should use these sharks do to the heavy lifting, look at the speed how BTC ETF got to 10B, and ask every store you go to if they accept Bitcoin, that's how we win. ... IMHO of course.
