Betpanda doesn’t request kyc from player's that they dont suspect of any wrong doing, or have not reached the set withdrawal limit for none kyc accounts..
More like they being suspicious of the user's activity, from playing small to mid amounts, then become huge and then winning straight, plus huge withdrawals. Actually, it's almost the same pattern for all of the reputable casino. That's why it's weird for some that KYC is being asked uoon registration.
