You actually just spoke the exact truth my friend, regarding the reason why our government hasn't fully implemented a defined rule or terms and conditions about cryptocurrency usage in this our country. Since we all know this politicians haven't figured out a way to directly benefit from Bitcoin just the same way they share money in the National and States assembly, hence, delaying to pass bills to law that will favour common Nigerians, than themselves. But on the contrary, I must confess I'm 100% satisfied with the current policy regarding Bitcoin and crypto transactions. Since we have got certain exchanges who offers direct buy and sell of Bitcoin with our Nigerian Naira fiat currency, who has been seamless and effective over the years. Because if we are to have an open regulated policy about Bitcoin transactions, we should be rest assured of been taxed heavily, most especially during this current Tinubu regime. 
All the national assembly members and our senators are all old fashioned and careless about Bitcoin or crypto in general and are not really interested in discussion like that. They're used to the commercial banks and they do know how to cover up their tracks, they like something they can control and not something way beyond their control; politicians hate things beyond their control and that's why most countries are still struggling to accept Bitcoin as legal tender. 
If they could control Bitcoin, I'm confident we'd see twice as much adoption as we do now.
