Honestly, If you have to post questions all across the internet to learn how to secure your system, then a BitCoin gambling site may not be for you.

If I was programming a bitcoin gambling site I wouldn't share any of my sites inner workings anywhere online.


I would suggest asking specific questions such as, What is the benefits of writing to my database using PDO vs mysqli or mysql?

The other thing you could do is hire a professional to come in and secure your system for you.

Good luck.
