I tell you what, this will be interesting if Yobit starts to pay 0.0003 per post for all accepted rank (Sr+). This will make 0.042 btc per week. Run it for few weeks, pay regularly, promise a long term campaign - you will see a lot of them shamelessly will leave that campaign and join here.
Going from 50 posts/week to 140 posts/week for 12% more payment is hardly worth it. If YoBit does this, put your money where your mouth is and let's make a bet that no one will willingly leave from the campaign and switch to YoBit within X weeks.
Or better yet, I'll offer an alternative pay structure for ChipMixer that matches your suggested YoBit offer. It's even better because you don't need to promote a shady campaign. How much would you like to bet that no one will switch? If just *one* person switches, you easily double your money. Keep in mind that you believe that a lot of them will switch. This should be the easiest money you've ever made.
