Necessary/requisite skills for theoretical/practical understanding of bitcoin?

[sp564]

Hi all,

New here and very much interest in trying to understand the blockchain technology on both a theoretical and practical level. I have no previous experience with coding, and was wondering what you guys would recommend. I'd like to eventually be able to become a developer and also understand how everything works theoretically so that I have a better understanding of the implications and possibilities for my own line of work (healthcare sciences).

I've been following Codeacademy's introduction to Java and Princeton's BTC and Cryptocurrency MOOC -- what else would you guys recommend?

Thanks in advance!
