I have a very small amount of tickets, just 2... lol
I received only one ticket, and I was sure I was getting more because I played with more money.
And I played with doge coin and I received tiny bitcoin amount with redeemed ticket.
So, we don't allow players to redeem rewards in any currency they want. Each account has a redeem currency which is the currency you have used (wager volume) the most.
I think it is better to redeem in crypto coin that you have most in your account balance.
