It is more easy than you think.. 20k satoshi is around ~$0.10, so to make 10.000 exchanges he need 100 users who will do 100 exchanges each, to earn $10. ($10/$0.10=100)
The question is whether it makes sense that 100 people is working to earn $10
People sometimes have crazy ideas!
you went wrong with calculations, these ppl are not going to work for me but for personal goal
first part of offer is to attract ppl
second part is to work as team and we can skip even part 1 to reach target
calculation:
can you imagine how long it takes to make 10K exchanges to get reward 10$ if site provides only ~50 tasks per day?
but now lets say 30 members team comes in and everyone upload 10 traffic exchange links that makes already 300 extra tasks
10000/350=28 so 30 active members will make 10$ each in 28 days
plus i didnt mentioned yet, you can also sell residual credits on site
plus if your own traffic links will be ptp, you can earn another extra
