Don't you check your account? 10 tron is already in your account. When you reach 25 tron, it will be automatically sent to your tron account.
I have invested 71.21 mBTC in Stake casino so far, but my account on GiveMeTron still says that I only have 10 TRX (this amount was added more than 6 days ago after I invested about 32 mBTC in Stake casino).
On GiveMeTron I did not notice that anything was changed except that this text was added next to the reference link to Stake casino:
Sign up with our referral link. all your wager earnings will be automatically reflected in your account at 03:00 gmt. You can gamble with any cryptocurrency and your earnings will be automatically reflected as tron.
Stake Earn %:
Wager * 0.015 = Your Earnings
Just continue until you reach the minimum wager amount so that we can conclude if this service is really paying or not. The OP is active in the forum in daily basis so probably he will credit your balance once he became online again. This service is not automatic and not following to the timeline on the faqs that he stated on his website. Probably he is doing everything manually without any help that cause this delay on payment.
