I think the subject of this post is quite baity because it is an article written where the author expresses his opinions and we can see at the top: "Opinions expressed by Forbes Contributors are their own." So it isn't Forbes actually saying it is a Great Scam.

Forbes recently published also this one: https://www.forbes.com/sites/ktorpey/2017/12/28/will-bitcoins-lightning-network-kill-off-altcoins-focused-on-cheap-transactions/3/# where the author seems to know about bitcoin (unlike the first one).

So, better think twice before putting those headings and not commenting anything else.
