I saw a lot of skeptics of BTC and crypto in real life, and lots of enthusiasts who see crypto world through rose-coloured glasses. I must admit personally I am leaning towards skeptics, I surely believe that future economic relations will change thanks to what BTC already did, but all those who say again and again"BTC is future, fiat will die" just do not understand what they are talking about simply misunderstanding what experts want to say.
Here is an article, which I believe provide middle grounds for both sides and would be useful for everyone here, in case you missed.
https://www.nytimes.com/2019/04/23/technology/bitcoin-tulip-mania-internet.htmlRegarding how big I thought Bitcoin could get, I began as a skeptic. I remember thinking things like "niche currency" and "internet novelty" back in 2014. At that time, "tulip mania" seemed like a plausible comparison. Not anymore, though. I'm definitely more of a believer now.
I think fiat will eventually be replaced by a return to a fixed exchange rate system with commodities like gold and silver. After enough time, I could maybe see bitcoins being used along gold and silver in the same manner too.
However, I don't believe Bitcoin will "replace fiat" and I don't think government-issued currencies are going away. I think Bitcoin is just gradually joining the ranks of commodities historically seen as "money" and I also think fiat money systems will eventually be replaced.
