To be fair, bitcoin reaching $150k or $200k is not as easy as many people think because we need $1 to $2 trillion to do that. I also want to know where we will get so much money in such a short time (7 months). But bitcoin always surprises us, so we shouldn't be too pessimistic. Anything is possible.
You realize there is a different between market cap and the inflow of money right?
A $150k-$200k price would be a market cap increase of $1T to $2T, but of course the amount of inflowing money needed to achieve that is a fraction of that amount.
So bitcoin doesn't need a trillion or two dollars to get to those prices, but maybe something like $100 billion inflow (without significant selling) to reach those price ranges. It's possible, though I don't think terribly likely in that short of a time. That'd probably take ETFs picking up several tens of billions of dollars the rest of this year, MSTR pick up a couple tens of billions of dollars, govts to pick up another ten billion dollars, other corporations to pick up another 10 billion or so, and individual buyers to go on a bit of a buying spree as well. At least to reach the $200k price. $150k is obviously quite a bit easier, but will still take significant inflow from new sources.
