I would tend to disagree with this statement, at least from the events of the past. Haven't really seen the expected uptick of adoption by major techies. Honestly, a guess here would be a stab in the dark - most of the giants (i.e Newegg, Amazon) have said they are 'looking' into it but I'm not that expectant that they'll follow through. Even if they do - it'll be converted back to fiat.
newegg
amazon
thats 2 companies that dont use bitcoin right now
tigerdirect
overstock
aria
thats 3 companies that do.. just off the top of my head.. but then we add:
https://bitpay.com/directory to the mix and have 20,000+ that do aswell.
so what lack of uptake are you missing?
