ok here's some predictions - admittedly there's a lot of IFs and assumptions but it gives you a sense of where this is going and why it's so insanely bullish.
Saylor is buying 10k BTC per week. Let's assume mining sales accounts for the rest of the ETFs and all other purchases (I don't think it's anywhere close but let's just assume conservatively)
We're talking 10k BTC pulled off all exchanges weekly. There are maybe 5 major exchanges globally right now? Coinbase, Kraken, Gemini, Binance, Upbit? idk, let's just say 5 for arguments sake.
This means 2k BTC are pulled off each exchange weekly. That's 285 BTC per day per exchange.
Let's look at Gemini's order book. I was only able to get it to display up to ~48 BTC cumulative, pushing the price to about $105k. If we extrapolate this, 285 BTC is roughly 5.9x from 48 (again it's conservative because liquidity usually bunch up closer to the current price. The further out we go, the bigger the price jumps). If 48 BTC accounts for a $3k price change, 285 BTC accounts for a $17.7k DAILY price change.
This means that in a single day, that would push the price +$17,700 across the board for all exchanges, in one day.
Now do this every day, forever, until saylor stops buying AND ETFs stop buying AND SBRs stop buying/never start up...
