Hello,
I discovered Roobet recently thanks to a Guess campaign promoted by Hhampuz. i was very luck and I was able to win a prize.
It is a nice website and I just made my first deposit.
I would like to make a small suggestion. I saw Roobet is still working with Legacy Addresses for bitcoin (addersses which starts with 1). Those address are more expensive and slower to pay/receive payments. I will suggest that you add the option to use segwit addresses.
Thank you very much and congralations on your successful project.
