Can any one give me an explanation about this???
Greetings
Signature campaign one of the best way to earn bitcoins very fast and easy. You need to check the right campaigns in service section. campaign managers use to select the person according to their post quality. Please avoid poor quality posts as much you can and increase your rank to get scope to work in signature campaign.
I wouldnt say the best way, since youre hoping that the main campaign manager is to keep it going...
But its a good place to start, but never should be heavily relied on and used as a stepping stone for something else.
