Lockdown is a crown sink. It helps balance the game economy by managing crown inflation. The 30% of crowns skimmed off from lockdown matches are effectively destroyed.
This is a good thing, it keeps the crowns you have from losing too much value. If there weren't enough crown sinks, CE prices would go through the roof.
And if you win half and lose half, say win 25 and lose 25 (75 koins assuming no bribes), it means you win 2000 crowns and lose 5000. 25 * 280 = 7000 minus the entry fee of 25 *200 (5000) = 2000. Minus the 25 * 200 for losing = 2000-5000. But like I said in one of my earlier posts, I AM NOT HERE TO DEBATE THE POTENTIAL FOR PROFIT. I just wanted to know where the lost crowns go and why they go there. Please read my entire post before bashing me.
