Ask HN: Month self study program for data science and for blockchain developer

I'm looking for two (separate) 6 month self study programs: one for data science and the other for blockchain development. Goal: Be able to get an entry level job (~$75K in San Francisco). Do comment on the feasibility of this goal. Background: - Strong Computer Science background with advanced degrees but I went to school when there were green screens, and I have not written a line of production code in ~20 years. - I have 10-20 hours per week. Preferences: - I find that instructor-led programs are too slow and I get bored; hence, a self study program. - I want something with massive amounts of feedback. The best I've found is Udacity for software development and Dataquest.io for data science. Haven't found anything for blockchain. Biases: This is not hard. It can't be hard when a non-STEM major can go to a data science bootcamp (like Flatiron) and have an 85% chance of getting a $75K job. Hard is winning the Best Paper Award at NIPS. Response to "if you could self study, you wouldn't need to ask this question" and similar: Thank you for your input.
