Too Long; Didn't Read
I explored a lot of Blockchain courses in Udemy, Blockgeeks, etc. Some of these courses are good. But, there is a room for improvement. It can be made much simpler, interesting and engaging. I recently came across <a href="https://cryptozombies.io/" target="_blank">CryptoZombies</a>. It teaches you to write a smart contract by building a game. It was on top of <a href="https://news.ycombinator.com/item?id=16113133" target="_blank">HackerNews</a>. There is a good demand for such platforms. I would recommend you to read the book <a href="http://amzn.to/2BZO4VZ" target="_blank">The Innovator’s Dilemma</a>.
