Or do these companies just treat anyone with a computer science degree to be an expert? (Heck, I'm a computer science student. Can I be a Bitcoin expert too?)
a degree is necesary to become an bitcoin expert but you also need to know about the ins and outs of bitcoin like what is bitcoin and how does it works . i know a few bitcoin experts but those people are famous . i guess being popular also plays a vital role of becoming an expert because people will easily recognize and believe on what you are saying .
