That could happen, but honestly, I doubt it. The reason is that the barriers preventing the use of bitcoin as a currency today are government and ourselves.
The government does not like the idea of a currency that is not under its control becoming popular. Meanwhile, most investors do not want to waste their bitcoin. Everyone just wants to accumulate and hold it long term with the expectation of making a profit.
Everyone is happy with the current situation and nobody wants to change it.
Years ago, in early years of Bitcoin existence, governments did not have regulations like now and will have more and stricter regulations in the future, so in the past, the main barriers is ourselves. In the present, main challenges are both, ourselves and governments, while people can change themselves and accept Bitcoin, they will have to face with and surpass barriers made by governments.
Sometimes, some people just want to leave in their comfortable zones and don't like to do things they feel risky especially if governments set up some barriers including legal ones. Governments will never automatically accept Bitcoin, and give freedom to citizens but in long term, I believe that with Bitcoin snow ball effects, its adoption growth will become big enough so almost no governments globally have regulations to ban Bitcoin.
