My though is rondm pin code for each withdrawal is better.
Wtf? Think about if you phone would have random pin every time you use it, how could you use it at all?
Or have you misunderstood the difference between captcha and pin code? Pin code is 4-12 digit
password.
No,you misunderstood my point.
we will make the script generator a random pin code for each withdrawal as Withdrawal Verification.
And if it is shown to you when you try to make withdraw, then it is just a captcha.
