Knowing the rules is an obligation, it's the same as; eating, drinking, and breathing.
Reading the rules and regulations may seems to be most annoying or boring thing, a gambler faces in an online gambling casino. However it is equally important to read the rules so avoid any unexpected thing or surprise in the future from the casino. Most of the time we dispute with casino and later found out it was already mentioned in terms and services.
The most thing that makes me crazy about online is delay in withdrawal and kyc requirements, ie failure to verify kyc details when submitted to them and lastly delay delivery of deposit. What I don't really like is after winning and they published your winnings like not secure while dealing online so everyone casino should limit how to publish people's winning.
This is what can make anyone to be crazy about online casinos, their is nothing else that can make someone to be mad if not delay of payment, finding it difficult to complete process to withdraw.
If casinos can make withdrawing process so fast , I don't think people will have any hard feelings concerning online casinos.
At which casino do you play where the withdrawals are delayed? There are many trusted casinos where you will get instant withdrawals.
I think if delayed withdrawals are a major problem for you, better change the casino. However, before playing at any other casino you need to see the reviews and what they say about withdrawals.
