A Bitcoin "expert" is literally just a label that people put on someone else. I want to believe that companies would have a bit more of a refined definition of what an "expert" actually is, but there's a decent chance that it's anyone who can describe the blockchain and has some tech/coding experience. There isn't a way that you can define an "expert" when there's no benchmark that they can be measured against.
I'd put money that anyone who can walk into a company and accurately describe the blockchain system while also flexing a Comp Sci degree or something similar can be regarded as an expert, whether they deserve it or not. I don't think that there are many experts out there, but it's a completely subjective definition.
That's what I suspected. Being a blockchain developer today is like being an aerospace engineer in 1910 or a web developer in 1992.
i don't exactly know what PwC is but with a little search it seems like they have a foot in financial services. so it is possible that "blockchain expert" in their definition translates into a person who has been making speculation in the cryptocurrency market. and we all know how stupid that kind of people are and they are far from experts but we have a lot of them.
it certainly wouldn't be the first time a company does this though.
They're a big accounting firm based in the UK. They tend to be more involved with consulting/advising/auditing the financial matters of a business rather than market speculation. Their clients are usually large businesses and corporations.
