Yes we all need the knowledge of how to make money both online and offline, because we have all realise that with the economic situation one can not depend on only one source of income as it doesn't seem to cover all the expenses we make looking at the rate of inflation in the country. So I strongly agree that we look out for other ways to help each other to make money legitimately. I will only advice anyone interested in working as a crypto currency trader to acquire more insight because there are somuch opportunities open for those that have a very good insight of trading.
Then as for offline business i would suggest we look at supplies, one could go into supplies of rice in large quantity it is very profitable. Again if you can drive one could drive for uber and make good money aswel.
