I have read few posts about how crypto and BTC can change the country for the better, and I fully agree to this but what if the leaders of the country are all corrupted? In this case I don't expect Bitcoin to help a bit, the leaders will find ways to start using crypto to their own advantage, maybe embezzlement of the country's fund.
This is one of the misconceptions some are having towards bitcoin, this is not a digital currency that is aimed at perpetrating illicit activities like financial fraud and it's clear that it's not a safe haven for scammers to hide, despite that there is high demands for one's privacy with the use of this same currency.
Another thing you may have to consider here is the nature of how bitcoin network operates, it can't be centralized because its working under a decentralized network, everyone interested to invest in bitcoin on his own can willingly adopt it use and invest without having to go through central authority.
