I started my path as BE 5 years ago and now I run a blockchain company.
My strategy was: 1 - learn just the basics on each vertical (bitcoin, EVM, smart contracts, consensus protocols, game theory) - it wasn't difficult having a background as engineer 2 - get a job as PM/PO to be in touch with as many projects as I can 3 - get a deep understanding of the market needs 4 - start working as low level developer on a particular (selected) project, to understand the core and become an expert 5 - manage my own team to sell services (outsourcing) to other entrepreneurs 6 - scale num.5
I share with you a doc I wrote a time ago, describing the roadmap I propose to learn the basics: https://medium.com/rather-labs/the-roadmap-to-become-a-block...

I wish you the best on this exciting path!
