Its difficult because you need to have a solid bankroll to start with and an exeptional reach.

First you need to buy a solution + license  and that costs +150k. You need to pay monthly fees to the providers and a revenue share with them.

You need to pay big money to a celeb or some big streamers, and they only want to go with you - of you can pay them more than they already get. Thats kinda impossible.

You need players from day 1 to survive in the competition or Else your bankroll will be eaten up by fees and monthly expenses.

Today new casinos opens daily but there is always the doubled who stops operation. 1 opens, 2 closes. We are sadly 3-5 years to late. Unless you get an exeptional idea that can make your casino unique. I just brainstorm but an idea could be to invite one of the streamers to get a share of the company instead of just being an affiliate. That could maybe open some Doors to a big audience quite fast.
