Does require a KYC to cash out? and how much the transaction fee in BTC?
No, we do not require KCY for withdrawals. However, KYC maybe required for our Jackpots currently at (1.2 million $) for regulatory reason.
We are working with our lawyers to improve our terms and policies to minimize as much as possible required information's if any.
Hi, Welcome to Bitcointalk Forum.

I just checked your website. It’s great to look at, great design. Though I am a dice fan, I really like your Blast game because of the UI and background music.
Thank you

We will release 16 unique skill games including a custom dice game just like Blast. We hope you enjoy it.
