Content delivery seems to be totally released in France, so it really could be the same in many other countries like in the whole Europe for exemple !
As I have barely half the day with it on, I think they have a lot of places and you won't stay a long time in queue anymore.
On this screenshot you can see that the feature unlocked itself only 9 days ago, and during the 8 days I could use it, I shared for around 107 hours. Wich make an average of $0,107 per day added to the amount of data I'm sharing.
It makes that even when you don't share much data, you still earn more than $0,15 a day :
Here you can see $0,115 for content delivery, $0,055 for sharing Data and $0,037 thanks to referrals. It makes $0,207 for a bad day and once again without doing nothing or paying more for internet.
I received my withdrawal the 1st of October and I already have $2,50 in just two weeks.
You can see on the picture that today I'm not sharing a lot, that's because I'm somewhere there is no such internet so I turn it on just when needed ( like for writing this post ).
