What a great article! Interestingly enough, I was reading another article earlier today that applied to the bigger picture; current development of the marketing domain within blockchain: blockdriven.com/blog/marketing-blockchain-careers. Let me know if this also helped clarify somethings up.
One article that is not direclty related to crypto trading, but was extremely helpful with regards to blockchain development in general and from a more focused product management lense: blockdriven.com/blog/product-management-blockchain-career. I suggest you give it a quick read.
