I probably wouldn't buy a ready-made project, as the likelihood that something is wrong at the code level is very high, in my opinion! 🙋

Imagine you've created a gambling business, and you're up against a player and the software code of your own casino. You'd go broke very quickly.

I'd start by exploring offers on sites like

https://www.softswiss.com/

https://www.softgamings.com/

https://slotegrator.pro/

You don't have to make a purchase decision right away. In my opinion, it's much more productive to talk to representatives of different companies, compare their offers, and analyze the strengths and weaknesses of each solution. Only after a thorough analysis can you make any serious decisions.

Also, keep in mind that purchasing the software is just the beginning. You'll also need to build up some cash reserves (in case your first players have incredible luck). You'll also need a sufficient budget for promoting your online casino.  The competition in this area is very high.

I'm not sure how well those bought scripts actually do from here. There's likely a professional service that offers this sort of service that can tack on crypto payments or a crypto API.

If you've no development experience and don't want to hire or partner with someone who does then you're taking on a lot of risk.

If you have capital and good technical knowledge, you can start it, but crypto casino isn’t a business that someone is going to rush into. There’s Competition, there is also regulations and security challenges and trust is a very essential factor. If you want to buy an existing casino, make sure you do a proper research about the platform and why it failed before putting your money into it.

The risk that is attached with copying a code when you don’t have an idea how it works or how to detect if hidden permission is inside is on another level, which no one in their right sense should be thinking of. Even hiring someone with the experience when you don’t have a clue is not advisable; the op should look at this before making any decision.

Imagine a closed source computing programs and coding, you think the privacy will still be trusted when certain individuals had been running it before handing the project over?
Of course not, the trust already begin compromise because you don't know the past or hidden deeds from the history of the casino site.

You may also try as much to scrutinize the system and may find no error but the critical thoughts about human and trust will always be a disturbance to be rest assured that the platform is not vulnerable after other parties had operated it before you.
So I either dont fancy buying already used or made casino site.

That is the problem with most of these online stuff, since it's not an offline one could get filtered quickly and if they do not have the right contact or direct contact to which they would get then there would always be problem.
For me, online is all about luck and if they get the right contact then fine, but however I believe there would always be a trusted user here who may offer such services to them without getting scammed.

Well, I am not sure how many offers you will be able to find here on the gambling section of the forum.
Why don't you put some effort on your business and start from the ground up with your own brand, your own team and your own experience to give to this ecosystem?

If you are trying to save money by acquiring something which is already done, then you may end up having a bad experience in the end.
There are no shortcuts with comes to building a casino, you know.

This user seems genuinely curious on what he is asking here. Most of his post is related to casino built up and he is truly trying to develop his own casino based on his first post in the forum https://bitcointalk.org/index.php?topic=5535568.msg65180516#msg65180516

It’s normal to seek public opinion if you don’t know how a transaction like this proceed especially for a user that doesn’t have experience on casino operations.

We are lucky to have sirjohnvon here. I’m honestly surprised on the minimum amount involved for white label services. I thought it was way cheaper before.

Beyond the technical advice others have given, there are some hidden costs and operational aspects of the casino business that you need to be aware of. First white label providers not only charge an initial setup fee, they also typically charge a 10% to 20% share of your casino’s Gross Gaming Revenue and a fixed minimum fee (usually $2,000 to $15,000) per month, which you must pay even if you don’t have any players. Second because of the sub license, you can’t integrate your own custom payment gateway or any other unofficial game provider.  So I would say that if you’re starting out on a tight budget, using crypto iGaming API Aggregators instead of full white label can be a cost effective and smart way to go.
