It depends on what is good quality for you. Free content usually has a bit lower quality, since plagiarism is a crime. We'll see how cryptoflix will deal with it. As far as I understand, they plan to introduce educational content later, after the main platform will be ready, right?
Students (and even non-students) will appreciate high quality educational video content. Right now the only source for those is youtube and you don't even find what you're searching for most of the time
There are educational subscriptions sites like udemy and other services. Full course and training
Educational videos would be a nice addition. There is still no plattform with both on it.I'm not that much into theoretical learning but if I had the access to such videos on hand - sure why not have a training lesson inbetween.
