|Udacity Blockchain Developer|
What to watch out for? Udacity tends to be experimental. Being in the first class may mean better price tag, but potentially extremely hard-to-follow incoherent content. I definitely had the issue with Machine Learning nanodegree when it first came out.
It does seem like one of those startup prototypes: standard format, basic content, with some industry professionals supporting the course including: Coinbase, factom, madhive.
Definitely worth it if your company pays the bill. Otherwise, wait and see better results.
