I like people to read insightfully, and if I were you I would surely have known this is the summary of part of what the OP states.
No. OP is not relating it to economy just as I stated before, he is relating it to individual and fiat.
Bitcoin is an asset just like any other asset, it has its earning and losing seasons, and it can never take the place of fiat and banks and cannot add to any economy due to its privacy and decentralized nature.
Bitcoin and cryptocurrencies can add to the economy. It is Nigeria government that do not understand how it supposed to be. I expected our government to have targeted crypto exchanges, other centralized crypto platforms and individual to start paying tax. Binance, Bybit and other exchanges are only making profit from Nigerians but the government do not make profit from them. They can even enforce all these exchanges and centralized services to have offices in Nigeria and employ Nigerians. Instead of the CBN to put light into this, it put more darkness when Nigerians continue to adopt bitcoin and other cryptocurrencies.
Indirectly, bitcoin and other cryptocurrencies will add to the economy. Example is if I invested $1000 in bitcoin and it increyase to $10000, my spending will increase. If the spending of people increase, that means more production. It is left for Nigerians government to look for ways that they will export than importing. If not bitcoin, there will not be anything called Bitcointalk, even if what we contribute on this forum is negligible, it is still part of increasing production as we earn money to spend more. It is not only this forum, I pointed to this because there are many ways that Nigerians are earning with bitcoin and cryptocurrencies in general, which will lead to increasing production in the country.
As for fiat, it is one of the ways people are scammed by the government. The government created a currency from nothing it is backed with and they are manipulating it. They are manipulating naira by devaluing it over time. If Nigerians are embracing bitcoin and other cryptocurrencies like stable coins as a hedge against inflation, I do not see nothing better than that. Only what crypto enthusiasts will see useful about naira is to convert your coin to fiat and spend it immediately. Nigerians on this forum will be crypto enthusiasts because naira does not worth holding.
