i do not know where all the good campaingns gone and why did any new camapingn is not openning. sigmature campaingn are the good way to earn money rather than fauceting for small amount of coins they saves lot of time and also where a good way people can discuss about their problems
Bitmixer & Bit-x are probably the only one who are running since long time and still paying however they are closed since they opened long time ago and have plenty of users .
Now why there is no new campaigns ? simply because It need a lot of investment , beside that you need to make something good to advertise otherwise It will be just a waste of money and there is a lot of competition (take Gambling websites for example , there is plenty of them , but only few like PrimeDice are getting "really" used) .
