No, they're practically right. Its simply, they are being "economists" at this very point, its not doubt, uncertainty, and fear. I mean anytime it could happen, the downfall of Bitcoin that is. Also, an asset, a product or currency itself or whatever you call it, that doesn't really benefit the economy, then its just worthless to them. And because cryptocurrencies are decentralized and volatile, people are taking advantage of it and most of them are retiring from their jobs to focus entirely on cryptocurrency. With that it will result a big impact to the economy; the loss of executives and employees, may also be workforce, skillful personnel etc., that's why it is a threat to them. They just intend to help the economy.
