Really, i don`t see a problem to bet 5x in casino. If you choose a casino for a long gambling you easily bet 5x.
Playing in a casino for long time is OK, but imagine of you have just made a deposit, played for a while and you win 2x-3x of your initial deposit and you cant withdraw it because you have not wagered 5x as per rule.
This rule will force you to keep betting until you meet the wagering requirement, which means that there is a chance for you to lose what you have just won + your deposit although there is also a chance for you to win more.
However if you are type of gambler who have a limit/target on every gambling session, this rule will destroy your target/limit on winning.
It is possible, but i think that such situation is typical for gamblers that gamble for short periods. For them it is awful requirement - it is true, but if they know about it they can choose other casino i think. We can choose casino for our own requirements.
However, choosing a new casino in such a way that it suits you exactly both in terms of the withdrawal option and how and how long you play is not at all easy.
If we look at the game from the side of the casino and at the complex of issues related to the transfer of money, especially in the case when the player has won, we will see that almost always the casino rules contain various tricky formulations in order to slow down the withdrawal processes in some cases.
Obviously, the casino always wins if the clients' money stays in the casino's pool of funds for as long as possible. And it is obvious that the actions of the casino are aimed at the longest possible preservation of the largest possible amounts of this pool.
And if you put your money on a deposit in a casino, it's always easier than ever. It is far from always very easy to withdraw money from the casino to your wallet. Of course, this is generally the general property of money - it is always easy to give it, it is always difficult to receive it.
I'm afraid that just picking the perfect casino, without sudden, unexpected KYC, without large commissions, with very fast processing of output transactions, especially if they are in bitcoins (especially now that the bitcoin mempool is completely crammed with stupid NFT transactions!) hardly someone will succeed.
Well, maybe only the lucky one!
If he gets lucky too.
