Hi Paddy
Although Bitcoin has a lot of attributes of a scam, there really is no evidence at all that Bitcoin was conceived as a scam. I don't know one way or the other. But I have not seen any evidence.
Some of the other ICOs are pure scams. But then again, if I show you a bag of hot air and tell you that it's a bag of hot air, but other bags of hot air are selling for $20,000 each, and you pay me $100 for my bag of hot air, is that a scam? If I sell you a gold bar for $1,000 and in reality it does not exist, or else it's gilded base metal, that is a scam.
The rest of the article is very good.
