It's not applicable to everyone yet... If you click on that link, and you are not one of the countries where it has been implemented, it will give you this message --> " Bing Rewards isn't available yet in your country or region."
This will make it interresting for the people who use Tor
I am in two minds about this... On the one hand, I am glad they started to use Bitcoin, but on the other hand... Should you use Bitcoin to dominate a specific market? If this sparks a competition between Microsoft
and Yahoo and Google, it would be a good thing. I just wonder why they do not reward in Bitcoin directly? The reward could be limited to a few Satoshi's a day and amount to a small amount a month. This way
poor people could benefit from this. This might even be funded by a Bitcoin merchant network in a specific area... and not from the corporate entities.
