Is there any first deposit bonus with less wagering going on?
There's no first deposit bonus, but they do have a
level-up bonus for their VIP program.
What about KYC? Is it mandatory? if yes, what are the documents required?
You'll only need to complete the lowest level of KYC where you'll fill in the basic information (Name, address, etc.).
Cashouts are instant and automatic or not?
From my experience with small amounts, it's usually near instant.
