Yes i do own the script, support is offered even after purchase and setting it up, I have created a discord server for vouches and to discuss everything together
Now why its for cheap? Ill be honest im gonna sell it for few times instead of finding 1 big buyer which might take time
After support is very important on a platform like Casino, do you already have a client now that has purchased your script? its better for him to give a testimony of your after-support.
Since you are selling it many times, are you going to customize every script that you are going to sell? If not, we will have a lot of duplicate casinos using your script, where the only difference is the domain name.
