For me to compare bitcoin in fiat, gold and other source of currency, bitcoin still has a lot of space for improvement bitcoin hasbit's disadvantage and advantage of course bitcoin only rely in the internet but it make transaction much more easier but fiat on the other hand is tangible it means you can see it with your own eyes and hold it with your own hands and that's what i think why a lot of people still not interested in bitcoin because what they want is the tangible one.
I would not say the reason why fiat is more tangible is because you can see it with your own eyes. It has always been the traditional means of payment for a very long time and just very few people know about bitcoin which is why I agree with you that bitcoin still has a lot of room to grow and develop.
Bitcoin is very useful and also not easy to just come by most especially these days and it is normal because assets too are always like that and the early adopters are always the ones to reap most of the benefits. So, I would rather say, time will tell, because right now, everything is evolving.
Like you said ; time will tell.
Thanks for your comment.
