From many months i am thinking about what if " we remove fiat system , and change things into crypto " .. What are the main difficulties we will face ?
1. Internet every where is not yet done.
2. Awareness with Crypto ( but its not a big thing, as most are aware of how to use currency. )
3. Bitcoin is only 21,000,000 and world population is more. ( This can fix by other altcoins same like USD/RUB/CNY etc )
What other difficulties we can face ?
#1 - This is the main hurdle. Even in the more advanced countries, there are still areas that lag behind with regards to the internet infrastructure because of the isolated location, you can just imagine how it would be in poorer countries like mine. Using mobile internet has been a solution for some people. I believe there are also plans for "balloons" that would extend mobile signals, and hence internet connection.
#2 - With the recent hikes and then futures, bitcoin is in many people's mouths now so they'd probably be more receptive to learning about it.
#3 - This is the reason why each btc is divisible into really smaller satoshis, up to 8 decimal digits. Try looking up the value of a satoshi in a converter, it's still negligible despite the $17,000 exchange rate.
