And I don’t think it’s a lowbrow straw man to point out that stock has some fundamental value as the present discounted value of future cash flows, and Bitcoin doesn’t.
TSLA has far more speculators in the stock than users of the product - which was the criticism levelled at bitcoin by OP
You mentioned TSLA has future earnings, which is true, but it has 12bil of debt of the balance sheet too. Bitcoin has no debt on the balance sheet..
More significantly, TSLA is trading at a normalised P/E ratio of >700. For comparison, FORD is about 14. This says that unequivocally people believe TSLA is far, far, far more valuable that the sum of it's parts. Just like bitcoin.
