In that link there is no reference to actual transaction volume, it doesn't say anything about how much money is spent (aka dumped) on merchants accepting bitcoin with Bitpay, if this number has increased or if it's anywhere significant. also, it doesn't tell you who is dumping spending their bitcoin on merchants accepting them through Bitpay. Whales who already own plenty of BTC? a limited number of libertarians? or people buying bitcoin to use as a currency for its *amazing advantages* to fiat money?
I highly doubt it any significant amount of money comes from the latter group, and bitpay doesn't tell me anything about that.

Because that was my point, people buying bitcoin to use it for its supposed utility as a currency.
