You`re right about new casinos. They try to get new gamblers with all kinds of rewards and it can be a good choice for bonus hunters, but the same time new casinos can be a scam. For gamblers, that wants just to gamble - old casinos with good reputation can be the better choice due to their account bounty program. For gamblers that want to play for a long time it can be better decision.
Anyway, we can`t change the casino politics, we can just choose the casino we like most than others.
If we talk about which casino will be the best for you, then of course you should first of all consider casinos that have been operating on the market for at least several years.
This is a guarantee of their conscientious work. As for the questions about the profitability of the casino, I agree with those that our colleagues answer here. Indeed, the design and, in general, a pleasant and convenient arrangement of controls on the screen of your computer or mobile phone are of great importance. In such a casino, you want to play more and more. And even sometimes it does not make sense to switch to new casinos with an unusual design for you.
Perhaps such an ideal casino for you in a sense can be considered the most profitable.
There are lots of moments that we are looking at choosing a casino. Design, RTP, bonus programs - for different types of gamblers have different worth. I can`t talk about others but for me, as lazy gambler, the most important are a guarantee of stable work without problems with deposit/withdrawal and pretty design. And i think that for someone, who spend lot of time in gambling - RTP and bonuses may be more important.
