At this point, its essentially TSLA against Bitcoin since MSTR is all Bitcoin. The question is, do you consider it easier for TSLA to 10x or Bitcoin to 10x?
I don't see how Tesla can grow much bigger than this since its already highly overvalued. If FSD is ever a thing, and nobody has to drive again, then I can perhaps understand higher valuations, but I also think this will actually drop GDP in general. Think of all the delivery drivers out of a job and the need for actually less cars if a bunch of robo taxis are able to pick you up for a fraction of the price of a current Uber. And if the robot replaces jobs, that also means a drop in overall incomes, even if productivity for some companies increase.
Bitcoin on the other hand is getting ready to steal the financial premium away from gold and real estate. Tesla compared to Apple, the biggest company, is a much smaller multiple than Bitcoin compared to the market cap of Gold, or even real estate. There is therefore way more upside for Bitcoin, and both I guess have the potential to go to zero.
I'm invested in both BTC and TSLA. I used to trade MSTR until it sunk.
BTC is a financial instrument subject to enormous political pressures. It can go to the moon or fail on a few decisions. To me it's a speculative bet.
TSLA is something entirely different.
