BitZuma is an online learning center where newbies in the area of cryptocurrencies, mining, wallets and even exchange. This course was developed by 4 people in 2014. Initially, they had only published 11 videos which were later cut into 60 more comprehensible videos. The courses here are acutally very simple with consie and accurate explanation, by well experienced people in various aspects of cryptocurrency. As Bitcoin is the main topic of discussion, hence topics like: Bitcoin mining, Bitcoin Storage, explanation of bitcoins amongst others topics, I have actually taken alot of things from this lectures by the organizers. I didnt need to sign up as their videos were easily accessible on Youtube. This course should actually focus more on other cryptocurrencies apart from Bitcoin. Currently they have a lot of views on YouTube but this views can still be increased if they broaden their topics on cryptocurrency and how they affect human lives. Apart from YouTube I would suggest that they have a website where there us a sumnary of every course taught this will further increase users comprehension
