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 ?
There are a lot of difficulties that those people who are not updated with technologies or there's no trace of innovation in their places and those people who'll be affected are the ones who are living mostly in remote places.
1. Internet every where is not yet done.
Biggest concern, we can't transact to those places that doesn't have connectivity.
2. Awareness with Crypto ( but its not a big thing, as most are aware of how to use currency. )
Lately everyone will be educated to crypto just like this year to many investors came in.
3. Bitcoin is only 21,000,000 and world population is more. ( This can fix by other altcoins same like USD/RUB/CNY etc )
Not a problem, we can buy and spend bitcoin in fractions.
