The screenshot may speek for itself but I'll explain further. In today's crate rush you can gamble to spend A-coins for the chance to win Legendary Sniper pilot - Morphio. There are 30 posible awards and as expected the chance of winning the pilot is the smallest known to human history. 

In my experience usually the game will give you the pilot LAST or 2nd before last. I know because I have 2 legendary pilots won from crate rush but with credist. Both of them ending up around 1 000 000 credits. So there is a huge chance to play the roulette 30 times. 

30 x 250A = 7500 coins for a pilot that is in no way different from the other 2 legendary sniper pilots which can be bought directly. 

Happy spending!
