I had 6700 crypto, enought just for one battle so i decided to give it a try.
Entered at a player's table, he kicked me out and when i tried to open my own table i didn't had crypto.. 700 left, and no cr in my collection.
I assume that i lost the battle, but it was weird because he kicked me out..
Like larry said you are supposed to get a result message. If you didn't get that please contact customer support and you'll get reimbursed with your lost cryptocoins.
Also, you could sort your collection to 'date', maybe you've won a cr but didn't see the screens.
