I think 1% is the lowest gambling casino's house edge can go. If they lower it than 1% then maybe the profit it will generate won't be enough for the website's maintenance and for salaries to its employees as well. If it's above than 1% then it would be difficult for them to attract new users.
That's right dude, casino is indeed a gamble but it must have a business system in it where developers and users are both benefited and not one-sided. If they apply a house edge above 1% then it will benefit developer and vice versa if below 1% it will benefit user. In my opinion, house edge 1% is standard of a casino and that is average of all casinos. If I find something lower than that, then I should be aware of the casino.
The income of a casino actually depends on the volume of money being wagered. It's nearly about house edge percentage of total money wagered in long run.
So the profit of a casino with .5% house edge is half of 1% house edge on equal amount wagered. Even a casino with house edge 0.5% can make huge yields if it's successful in bringing people to gamble more money.
anyone can wagger high amounts with a small balance as long as they will use appropriate strategy like 1.01x on dice with a higher amount of bet . i think the amount waggered is not a basis of thier income not unless if all of those who waggered big are loosers or have lost huge amount of cryptos . 1percent or lower than one percent , it does not matter but they can only earn big if they have a lot of costumer that plays on them . they can only do that if they have a good and fair service
