I think you all are heavily underestimating how inefficient the capital markets are. There's money trapped in convertible bond silos that can't buy anything else and mstr is how that monetary energy is being pushed into btc. But there's way more that just that ~1 trillion market. The arguement that eventually mstr runs out of buyers is true the way eventually we have the heat death of the universe.  The interesting things are between then and now.  

 Perhaps... I would say you just may be heavily underestimating the effects the next typically severe bear market could have on MSTR's appeal as a derivative of a disappointingly performing commodity.

There's not much point to quibbling over what is ultimately unknowable, though.  Suffice it to say, I would be perfectly happy if the mania continued until the heat death of the universe - BTC coming along for that ride is good enough for me.
