BTC is gradually gaining its grounds in the financial institute. Most people prefer using bitcoin as a medium of exchange.
I think you answered your question from the headline by yourself with these few words. It's happening for a while, +10 years, you know. Bitcoin is gaining trust from all sides, even with so many naysayers around... and what happened with some big naysayers around? They joined bitcoin after some time, they changed their mind about crypto after few years of watching how fast we are growing, by that I mean crypto community and all of us with it.
So what future holds? More adoptions, more development, more options, more of everything I guess, practically nobody here changed their opinion about bitcoin and bitcoin future once they joined, when you get hooked by crypto it's like for life I guess.
