So, you are trying to sell Gambing Script huh? So let me tell you something, After someone purchase the site and run it, what if the player registered on the site is you? Wouldn't the site owner on deep sh*t/red after you playing for a while?
They are trying to sell their gambling script to earn few penny nothing else. I do not think this script will be anything effective. It will be just wasting a few money.
Script are used for the bets to be automated. So scripts are effective in saving time and effort. Same as automated betting offered by ol casino sites it is just that what they offer are simple automated betting. It is not wasting a few money if you used it and it was effective (but it may do the otherwise ofc)
