Not only @OP but all we readers are learning from his experience. This thread will serve as a "warning" for people who value their privacy and probably avoid playing in FJ since the casino implements a mandatory KYC to be able to withdraw our funds. At some point, the email sent to @OP is somehow a borderline scam telling @OP that he has free money on his account but does not. I believe any form of trickery to entice a person to play and deposit money on their platform and give the player a hard time withdrawing their fund is a shady action and is a borderline scam just like the email received by @OP. The marketing personnel that create that kind of approach should be reprimanded.
It looks like @OP won't be doing any kind of KYC,
i would probably play the amount with my best strategy in the casino, and grow the money up to $5k if possible before doing the KYC. if all is lost then just get out of the casino for good. just hope for the best to happen.
they are the first casino that asks KYC with an account with so little money on it and if no other casino does this, FJis probably losing the competition in the crypto casino race. they had not advertised much since the time the Stake, etc arrived.
