However, I don't foster any negative feelings towards developers per se. A job's a job, and crypto isn't exactly as easy as your run of the mill CRUD application development.
By working in the ethereum space you've proven you can work with/around obscure tools, learn strange jargon, probably have some knowledge of cryptographic algorithms, and a willingness to do a deep dive in what you believe in. I'm no hiring manager, but to me that all seems like a bunch of skills that will transfer to many businesses outside crypto.
There's more to a person than what areas of business they have experience in. You can work for Big Oil, Facebook/Google/UmbrellaCorp, or Nestlé and be a perfectly good person just doing their job. Anyone refusing you simply because you worked in crypto at some point is short-sighted.
Even if you are a crucial part in the next big rug-pull-sold-as-ending-world-hunger, I honestly doubt you'll run into too many ethical qualms unless you screw up enough to actually break the law and get caught. It's not like Meta or Wells Fargo suddenly care about ethics if you can talk things straight enough, most big companies are morally bankrupt anyway.
