What is KYC?

What's a pending period?
The time a withdrawal waits before the casino processes it, during which it can be reversed.
Gambling should be entertainment, never a way to make money or win back losses. Set limits before you play, and take a break if it stops being fun. Free, confidential help is available 24/7.
