can I join also?
Yes.
OP, the way you've put it is very confusing. Just put it into simple words: For instance, answer this one simple questions WITH A SIMPLE ANSWER:
If all 20 slots are taken and I make 100, 150, 200, 250 posts, what happens? Am I still paid, if not, why not?
He has made it pretty simple.
There are 20 simple slots and 5 overflow slots.
20 people will get the first 20 slots worth of BTC.
The first person to get 100 posts will get one of the overflow slots and will be paid his normal amount one more time.
If one person makes 300 posts , he can get all the overflow slots for a grand total of 6 times his original payment , but only if he does this before anyone else makes 100 posts.
TLDR; If you make 50 posts after being verified , you are guaranteed payment. The extra bonuses need you to post a lot and fast.Exactly. Thanks for the clarification
Hello Genesis-Mining, your rates are the highest i have ever seen so far but would you do a weekly payouts for example if i would do 12 posts in a week would you pay me 0.0375BTC for that?
No.
That'll be a super time-consuming process, to whoever is going to check to see who really DID make the extra posts or not... Because I think that they''ll be many users complaining that they were the first ones, blah blah blah.
Oh and @OP, I can also help escrow the funds if you wish

Yes, unfortunately. We will work out some better solution for the second month.
