Microstrategy holds 129218 BTC as of Apr 2022. Elon Musk's net worth is $222B as of today.
Even if BTC were to be $1M a coin (which is a mighty 33x from here), it would still be worth $129B in todays dollars or about 58% of net worth of Elon musk. For them to break-even with Musk, btc would need to be worth $1.718M in todays dollars.
Maybe this gives us an indication for the upside potential of btc if and when the Fiat Giants gets orange pilled.
