If they do it will be yet another place where Bitcoin can be spent to further reduce the price. I don't why this news excites holders.
You mean it would be better for Bitcoin if nobody actually uses it?

Get a grip. Bitcoin will only rise if it's being put to use, not if people are just sitting on it and waiting passively for something magical to happen. Then again, whenever you spend bitcoins, make sure to buy back on the market or exchange. That's how you spend bitcoins and avoid price reduction (from merchants dumping bitcoins) at the same time.
