Where to start earning?
I tried selling things, but nobody is interested yet
Not just selling things because not everything is sellable so just as another member said, sell what is demanded and not just anything, this forum is a place to meet and discuss about Bitcoin and other cryptocurrencies so is a good place to market your goods and services and to make income.
Also try getting a real job, because online jobs are only for those who have skills and experience and also if you have extra cash flow, another best way to earn is by investing first, and investing I mean buying Bitcoin and holding them in your own controlled wallet's.
