Life would not have been difficult without crypto in Nigeria. There are a thousand and one Nigerian youth who are making a lot of money everyday, month and year legally who are not into cryptocurrency. Have you heard of Amazon KDP, Forex trading, SEO specialist, virtual assistant, drop shipping, affiliate marketing, Copywriting, Facebook ad specialist just to name but a few? These side gigs pay young Nigerians in hard currency. As you can see cryptocurrency is just one of the ways that made life a little bit easier for Nigerians but it is not the only way.
Bitcoin directly and indirectly helped me. Bitcoin and some other cryptocurrencies helped Nigerians. Some people could might have been poor if not for cryptocurrencies. There are many other ways to make money, but because of the existence of cryptocurrencies, some people are getting online jobs, even in areas you mentioned above and some people invested. Although, we have to be very careful, because cryptocurrencies also make some people got scammed. As for trading, people should know that it is very risky.
