Well, there are sites where you could earn and this is not limited to Ghana or any geographical region. This forum Trendri is the right place where you can start your earning journey. I'm also a new member here but from the reviews I saw online, I had to acquaint myself and try my odds by sticking to the laid down rules. You can earn about $2 and this is solely dependent on how well you can dedicate quality time, comments and threads which is about 12 comments depending on the word count and 15threads as well if you aim to earn $2 on a daily basis. The one thing I like about the forums payment system is that, it has an array of choices and even has the bank wire transfer system.
To earn substantially online, it would be best or to your advantage of you have the needed skills because the market is already competitive. In freelancing, you can edit, proofread, ghostwrite, write articles for blogs, journals and magazines and you get paid for it. You can also explore popular sites like; Fiverr and Upwork where you will set up your profile to attract customers. All these would be more achievable if your skills are reputable.
