It not easy to predict this, we do not know what the future will be, but more companies will accept bitcoin for making payment. Just that before bitcoin can become a dominant currency, the government needs to adopt it, but which they are not ready to do. Bitcoin does not depend on the government and it may be the dominant currency, but I do not think there can be a currency that will dominate USD for a long time.
Now the big major companies these days like TESLA for example are making big transactions with bitcoin making btc look viable and acceptable for exchange
Tesla accepted bitcoin in the past, but it is no more accepting bitcoin again for now. But there are many companies and sites that are accepting bitcoin through payment processor.
