I'm just curious when can I start buying my dream cars with altcoins, I mean can huge automobile companies like Toyota, Ford and Nissan start accepting cryptocurrency as means of exchange
You can do it today if you have enough BTC,for instance if you live in USA there is some car dealers who will gladly accept your crypto.For Europe it seems to be only one one car dealer in Italy for now,but somehow it seems to me that this information is incorrect.
However it will take some time that payments with cryptocurrency become commonplace practice,maybe in next 5-10 years you will not ask such question
This person is right about car dealers already accepting crypto currencies in exhnge for their cars and again it is not globally accepted yet. But again, if you're state side then you can definitely do it if you have enough coin that is. But you'll have to settle for the car companies indicated above.
