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 ?
If it get to that point of fiat converging into an digital banking or billing it would be ridiculous to not have a paper money its kind of creepy lol. Well facing it now but by little. As you say internet isnt worldwide some locations dont have the signal or the authority to acces the full operated internet. Its disadvantageous to those who does not have that and it will be difficult to those who are old enough to not even recognize what internet us or what smartphones even mean.
