Doge Tipping App:
Do you see BTC in the supported list? (
"...and more" includes BTC?)
Could you imagine Facebook with DOGE plus other alts and no BTC?

Ever since the Winkelwii went public about their Bitcoin investment, Mark Zuckerberg is trying to destroy the digital currency. Adoption of Doge might be a step towards that direction.
Zuckerberg holds a grudge, that said I guess he had no issues with anything the Winkelwii are not holding right now
As for the Citibank report they need to learn more and I agree with the opinion below.
What Citibank wants would turn bitcoin into everything Satoshi disliked about modern financial systems. Its clear that the general public still doesnt entirely understand Bitcoin, and as a result, bitcoin still has a long way to go until it sees widespread adoption.
