How many do you think would have read the article "Coinbase moves its coins to a new wallet"?
I think the same. This news was made by an author who wanted to do an article that people that are not that educated in the bitcoin space would read and that seems plausible. If you read more deeply in that topic you will find out that its just speculation that can never be proven. Still the author got what he wanted and thats your click and his ad revenue.
