I think it just means that Bitcoin is now at a stage that it is no longer undeniable especially if some of the biggest critics like Mr Schiff have folded and joined the bandwagon 
I will repeat myself again, Peter Schiff is a nobody. What a loudmouth nobody critic thinks is not important. Even if he joins the Bitcoin bandwagon it is as meaningless as his critics, stop giving useless idiots attention. He is not a nobody let’s don’t go that far eh?
Yes he might be a nobody among the crypto people (actually I think some crypto people love to hate him for some weird reason which I can’t explain) but he has hundreds of thousands of followers on various social media platforms.
He also predicted and shorted (meaning he actually made huge money) the mortgage bubble 2 decades ago and that’s the reason why you know his name today. He is not some random gold seller. There are many other gold bugs posting doom and gloom videos all day every day on YouTube but they have only a fraction of Peter’s followers and there is a reason for that.
