Bitcoin can be used as an investment and a hedge against inflation but it cannot be used to have financial freedom unless you have invested in it in the past and have gained like 100x return or more.

There’s also the issue of government regulations. The Central Bank of Nigeria has taken a cautious, sometimes hostile stance toward crypto, which creates uncertainty for investors and users.
With all the government hostility in the past, Nigerians were still able to trade bitcoin.
