You are wrong, not all Bitcointalk community waiting for new campaigns. I don't think that Bitcoin price have big role for number of active campaigns. Companies starting their campaigns when they think it's right time to do it. If Bitcoin price is growing, they start campaign with lover rewards or fixed in $ value. I can say that my campaign rates was always same, now matter bitcoin was worth $2000 or $7000. But I saw some old campaigns reduced their rates. And to my knowledge, campaign managers isn't responsible for payment rates. Company which run campaign decide payement rates, gives btc to manager and issue payments.
Instead of waiting for new campaigns, you should focus on improving your English and quality of posts, otherwise when new campaign will start, you won't be accepted. But you always can check bounties board - you will find many active campaigns, paying in tokens.
