The news regarding Starbucks is quite huge and its possible impact could be significant to the market.
There is no point in exaggerating this event. It's not going to change anything because nobody is interested in spending their coins.... this is nothing more than an effective way to generate cheap and easy exposure.
I have yet to see an instance of merchant adoption translating into price appreciation.... even more precise, merchant adoption actually hurts the price as coins are being sold to accumulate fiat to pay merchants.
The far majority of the merchants accepting Bitcoin through a payment processor don't care about Bitcoin at all, they just look to generate additional revenue in fiat, which I can't blame them for.
