Do I need to paste the definitions of fact, vs prediction, prophecy, belief and opinion in here?

I remember hearing similar pronouncements presented as 'ironclad fact' after Mt. Gox, and after the DAO hack, and even during the Bitcoin Cash debate. The field is more full to the brim of people presenting opinions as fact than I would ever have believed. Even if you were someone I'd heard of and respected, a known expert; if you claimed your opinion in this space as fact I would yawn and put my respect for you down a notch.

And, the discussion wasn't about market cap, top 100, or anything like that - just verifiable technical characteristics.

The scam talked about in this thread wouldn't work in Nano, because Nano doesn't require mining or fees. Many other coins have the same characteristics, Nano was an example. I would bet that any other example would have been just as triggering to people.
