Generally, people with advanced degrees in economics do not bloviate on Internet forums, and even if they did, they don't have much reason to share their credentials or their identity. Degrees or any other such qualifications are generally hard to prove, anyway, so why bother?
People with degrees are too busy making money to roam on some little BitCoin forum.
By the way, I have a PHD in Economics, Computer Sciences, Cryptography, Mathematics...
