An expert is only an expert when defined by those with approved opinions, usually not experts themselves. The real pool of experts will have varying opinions based on data interpretation, so there's no shortage to pick from of experts that hold the stance that you agree with and as such it's more about narrative than reality.
A great example is something like the '08 crisis, there were plenty of people who made a lot of money using their expert opinion, which they shared openly, but few wanted to believe them. It was considered to be the end of volatility and those claiming there was a crisis coming were just quacks, but there were many of those quacks and today they're seen as experts because history proved them right. Now let's say I pick one of those prophets, such as Peter Schiff, and listen to him today, I'll probably be listening to one of those experts who will be proven wrong as he has been with his anti-Bitcoin stance and the like, but hey, he's an expert that doesn't like Bitcoin and is a gold maximalist, so if that's your cup of tea you can present him as one of the experts that agree that Bitcoin is rubbish along with Warren Buffet and others. You'll be wrong of course, but you can find enough big names out there to make the claim that experts agree while discounting contrary opinion as denialism or having conflict of interest to push a narrative.
