Don't forget what Hal Finney predicted more than ten years ago, or rather his napkin math calculation. (TLDR = $10m USD / BTC) Still, that's going to take a few more years (perhaps another decade.)
I came to $5M / BTC after a quick calculation while pondering the idea of GBTC buying more BTC daily than mined daily. On the latter: if that's the case and we are truly in a new phase where there is relentless and relatively price agnostic buying on a continued basis above daily coin production, the question is simply:
=> at what point are HOLDlers willing to start parting with their coins?
I don't know how I could gauge that or make an educated guess on where that level would be. My gut reaction would be that $50k would make a few large holdlers nervous and that $100k can be expected to be a big 'cash out' (=redistribute) moment.
If anyone has a better scientific approach to this, let that person step forward.
