Well, to be honest a few lines in the article got me thinking.
Not about shutting down bitcoin (lol), or that miners might use txs for drugs crime terrorism...that's the usual crap.
We need a system which allows us to send free tx, unlimited transactions and high security with no chances of a 51% attack on the network.... a bit too much to ask unfortunately right now.
And of course ripple which is a bit too much pumped in this article isn't even close to being a solution.
I don't even think the author is stupid. He probably just really needed to write something controversial about crypto and this is the most original thing he came up with.
