It’s honestly complicated and can not be answered by a simple yes or no.

Yes it is possible and I can see it happening with how much interest and acceptance a lot of the people from different parts of the countries give to bitcoin. But does the government support this movement? A lot of them no. So it is really up to the government how much mainstream bitcoin can get.

Another thing is that bitcoin still has some improvements to make regarding the congestion of the network which proves to be one of the biggest problems bitcoin has faced so far. With advancing technology I have no doubt that we will see some breakthrough and finally solve this issue. Then we can think of having bitcoin adapted by a larger audience.
