Is there a prize for all participants?
There is a 30mBTC freebet or 90 mBTC (for 1 BTC + bankroll), as long as players have made the minimum amount of bet slips during the competition.
No, that is not true. Rules changed just after competition was already over !
I haven't received 90, but only 30mBTC, even I played with bigger bankroll

I will see if there is any problem, rules did not change. If you read the OP you will see they are the same.
