I dont trust people who have LinkedIn tagline with any of these combinations.

Blockchain
Machine learning
Artificial Intelligence
Expert
Mentor
Advisor
CTO
Startup

account manager

What's left out?

@SoulSkrix you can be one of them but not most of it. Like even Bill Gates or Woz will be only good at one thing. Building operating systems and stuff. If you're good at many things you're probably not good at any of those.

How about anyone with „marketing” in his title?

As for the first three, the fact that they're used as buzzwords doesn't make them invalid.

Advisor and cto are good ones too I think...
