Honestly, if a player's intention is purely playing on the casino, the wagering requirement for withdraw shouldn't be a problem. It is mostly a problem for people who wanted to mix their coins to remove traces of their history.
I believe that a 1x wagering requirement is sufficient to prevent money laundering and coin mixing, as many reputable casinos with excellent services have high requirements. During my research I discovered some casinos that only require a $20 bet size before permitting withdrawal using the same deposit method which i think is an excellent approach to prevent these issues and gain more players. A 1x wagering requirement is also reasonable and equitable since depositing $100 necessitates playing at least 10 times with a $10 bet size.
There are many legit reasons why a player would want to withdraw his funds immediately after making a deposit. Some of those reasons are: not being satisfied with the quality of the service, needing money for an emergency, don't want to keep your coins on a custodial wallet..
On the other hand, requesting a minimum playthrough requirement before withdrawing is understandable to prevent money laundering. It's just anything above 2x is simply not fair.
BTW, thank you OP for compiling a
list of casinos with highest no-bonus wagering requirements.
Not only immediately after depositing but even if a player makes a profit within the first few bets after making a deposit with these types of casinos they are likely to lose their earnings and even initial deposit while attempting to meet the imposed requirements. Given that several choices and casinos with similar services are now available I don't believe anyone would choose a casino that demands more than a 2x wagering requirement for a no-bonus deposit, logically speaking
