Entrecard has doubled their paid rates. In order to be fair to existing customers, they have doubled our balances. This is fair enough and makes sense to me--I'll still get the same number of clicks.
I probably won't run another campaign--4 cents per click is a bit steep for me. But I don't blame EC. They are simply following the rules of supply and demand, and 2 cents per click was a steal.
I think the more profitable Entrecard becomes the better it will be for the users.
