one of the biggies, Ebay, Amazon would be a great boost and awareness would go through the roof
Hopefully. Amazon or eBay would be huge. Maybe Facebook or you tube will implement or accept it in some way too.
i doubt they will, ebay has stated without hesitation, that it will not accept bitcoin, and it is one of the reason why they splits with paypal
amazon are not interested either , and with their huge volume how can 1MB limit sustain they TX per day?
forget about those, the next big one that will accept bitcoin, is an our internal friend, Open Bazar, will make obsolete those merchants, if done right
