A quote from the article:

“At current transaction costs/speed, Bitcoin is not useful for transactions. For every given transaction, there is a better cryptocurrency and often a better fiat-based transaction mechanism. As a “coin,” Bitcoin is not currently useful ”

For anyone out there dabbling in crypto-currency, this is a pretty good article that discusses “value” in the context of “usefulness.”
