Yeah many of the campaigns are getting down and it is not good news for us as it is the only source of earning bitcoins and if it keeps on going down it would be really difficult to earn bitcoins as we don't want to get into trading or gambling. So more and more campaigns with good payout should be started.
What are you even talking about? Campaigns affect little or nothing the bitcoin price or its stability, they are just a source of income in this server for some people but more than 70% of bitcoin users dont know or use this forum at all and 90% of the forum users dont even know or wear a signature to get profit.
Signature campaigns really can't kill Bitcoin.
