That's the key, im constantly thinking about non licensed crypto casino, might even dex casino. with top 15 crypto coins deposit option and 0.5% house edge at maximum.
If you’re going to choose the traditional crypto casinos, it will cost you that much.
DEX will be the best option for you and a Web3, try to search about Moonbet gambling site and see their platform and how it works. You’re good OP for considering everything before going live, its not easy but once you get what you needed, I’m pretty sure you will succeed. I wish you the best and hope to see your good site soon.
^I am taking pictures as a scenario here like the gambling casino Roobet, from scratch to the successful casino we witnessed different strategies they used. First, they won't ask for KYC but later on, as a part of a successful casino, they have to change their policy and become a KYC gambling casino. Probably, DEX or non-KYC casinos will not help if you wanted to become a successful casino.
However, I like the OP's question, an open mindset like this that will be considering possible mistakes in the future will most likely become a successful casino owner someday, those successful ones start from scratch, this depends on how you will market your projects which means, it needs a lot of funds before you can compete with the existing one. Being generous of Roobet and they claimed the fastest growing casino, they are now one of the largest casinos here.
