If Bitcoin 5X, then MSTR will 10X and MSTY will ~7X with dividends reinvested.
Anyone that was living off Bitcoin when MSTY came out in February 2024 would have more Bitcoin today if they had put a portion into MSTY than they would if they had sold Bitcoin to pay expenses.
I haven’t updated my spreadsheet looking into this for a couple of months, but with this price action, the numbers will break even more in MSTY’s favor, is my guess.
