There was this word from satoshi that we used to see on the banners that after 20-30 years, there could be huge transactions or none. While as of now, it's totally zero chance that Bitcoin is going to become extinct and it's here to stay.

With that statement from the creator himself just assures that anything can possibly happen. But looking on the situation, we'd definitely not going to see it any time soon that it will be gone.

Maybe in the nearest future, the interest might just be stable and not that be much anymore because of how things could change like having not that much fluctuation anymore.
