Here is an idea:

Bull market ends when MSaylor raises $100 bil at 150k/btc (and with a 8% coupon), btc pumps to 200K at which point MSaylor releases the cash, btc jumps to 250K and a week after it is halved to $125K and in another week to $99K...MSTR stock is decimated (from $1000 high) 'cause MSTR has no cash flow to pay that coupon and the bear market "begins" in earnest.
Destination: 62-65K (the usual 75% off)
