From my point of view, Bitcoin is not here to stay. The blockchain technology will get better and better ways to counter scalability issues will come up.

Will Bitcoin be able to cope with the rapid changes is up for debate.

Who remembers the first email client? Now we only know Gmail and a few new.

To get to your topic, I tried explaining Bitcoin to many people but failed to rise the interest of more than 10%.
People prefer government money as it is safer. The common man is not about hiding taxes. It is about getting money in the first place.

If government provide digital money, 80% will definitely use it out of constraints of the society. People don't want the hassle and the complexity of technology.

The most simple, valid, not corrupt and regularised will what the common man will take.

I believe that those who own crypto right now are those who know and understand the game changing aspects. The others are mere spectators watching to tell us:

"I told you so! Don't invest in crypto and now you have nothing."
