It's probably something that would not happen in a few years, but I believe there will come a point where the number of users, who will realize the benefits of using Bitcoin, will increase at a rate never seen before.
I think though users bitcoin is growing and very much it would not make bitcoin replace fiat, it's a sure thing! but for a price of course there will not be people who know about it, maybe the price will explode
definitely. it's just too hard for bitcoin to replace fiat and even if bitcoin just almost replace them if the government just banned bitcoin because it may threaten their economy,then the efforts will turn into nothing. bitcoin is really suited to be an alternate option but not the main currency yet or even replace the local's currency
