Would you buy Tesla using your Bitcoin or you will wait to $100K? 
I don't think so.
I'll use my BTC to borrow the $.
Borrow twice the amount needed. Half for the Tesla, half to buy some more BTC.
6 months the BTC will double or more.
You just got a Tesla for free!
Likely Tesla is going to own Toyota.
(unless Toyota performs a solid state battery technology miracle magic)
Right you cannot even sell a used Prius. Gotta pay someone to haul it away.
