Just predict WC's result in comment and get some SCR to your account. The rules are

 1. Write in comments the first three teams of WC-2018 for example "1. Croatia 2. Belgium 3. England".
 2. Vote for this post and and don't cancel it during 7 days
 3. SCR would be sent on July 18, 2018 in next size:
 - first accurate finalists prediction - 10 SCR
 - first winner prediction - 20 SCR
 - first top-3 prediction - 30 SCR.

Good luck!
