I think it is a good thing.  What I think is interesting is that the growing adoption of BitPay is not seeming to have a downward influence on the price of Bitcoin.  I would expect it to as - for the most part - BitPay is converting Bitcoin immediately into fiat.  That means they are putting a significant amount of SELL orders on the exchanges they integrate with.  I would think the growing use of BitPay would force the currency down.
