If my idea proves to be correct, will the government of the country accept it?
The government to accept crypto?, nah not yet,I don't think they will ever accept it, since it is a decentralized currency since they can't track or have control over it, they will never allow their citizens to freely use crypto in their country.
3. If the government can't keep track of people's legitimate money, won't corruption increase?
Corruption has always been there, even before cryptocurrency was introduced, scammers have been using the fiat for a long time to commit several money laundering and theft, just that since transactions done on cryptocurrency can not be tracked, alot of scammers will see it as a safe heaven to hide their stolen funds.
