Restrictions on the number of participants is only in the campaign signatures?
As I can see in first post number of participants is limited to 100 for signature campaign and to 500 for twitter campaign.
Why it is forbidden to write in Russian forks?
I don't see that rule.
Thank you for your answer
Indeed it's quite difficult to calculate the stakes now.
But in other bounties is mentioned for example that 1 token=1 $ and 1 token=5 stakes
It's not. Just go to spreadsheet, count all stakes, divide total bounty reward/all stakes and you will see how much tokens each participant will earn(ATM).
