Although this thread is not new, but it's a fact that Nigerian currency, naira, has been losing its value so much that now one USD is equal to more than 1500 naira. The devaluation of Nigerian currency shows that Fiat system is totally a failed system, and any time a currency can lose its value.
Now the Nigerian currency is losing its value, and who knows, in future, USD might lose its value as well. So that's why I believe Bitcoin is the way to go. While most of the Fiat currencies are losing their value, but Bitcoin is gaining value. So I believe it's the time to move towards Bitcoin.
