In my point of view, If toyota, honda, ford or nissan or any car dealers will accept bitcoin or altcoin as a payment it means that its a great opportunity to us. Because bitcoin and altcoin has making its name in the business as a payment mode. I hope it will come true but not only in cars but also in many business stores would accept bitcoin and altcoin as a payment. As far as I know there are some country that already accepting bitcoin as a payment in their goods but I do not know if there are countries also accept altcoin as a mode of payment.
