You have raised some valid scenarios that are hard to ignore but most of the position you have maintained would only be possible if there is no human element involved in the process in that all of the processes are automated without human intervention but that is not the case as follows
Anonymity
When users play at a traditional fiat casino, they are required to provide the platform with a range of personal information. Moreover, they are expected to upload multiple documents such as a passport, proof of address and a copy of the payment method used to deposit.
On the contrary, online casinos that specialize purely in cryptocurrencies are not required to follow the same set of regulatory red-tape. In most cases the user is required to supply nothing but an email address, subsequently facilitating an anonymous gambling experience.
The bolded won't be there for long for one reason is the gambling world of crypto currency is everyday infiltrated by people who want to hide under the anonymity to perpetuate fraud because of this players would need protection and that would come as a result of ensuring the gambling sites have legit license to operate. In other to acquire such licenses, they would be forced to implement KYC rules and the users would be forced to settle with bad of two worse situations.
Speed
Although the deposit process at fiat casinos can be instantaneous when funding an account with a debit or credit card, it is the withdrawal procedure that really struggles. When a player makes a withdrawal request, it must first receive authorization from the platform's internal payments team. Moreover, if the player is yet to have their KYC documents verified, this can add additional time. Once the request is processed by the casino, the player must then wait until their respective card issuer settles the payment. All in - it can take up to a week before the player receives their winnings.
On the other hand, online casinos that specialize purely in cryptocurrencies are able to process withdrawals instantly. Ordinarily, the platform will process the request in an autonomous manner, subsequently allow the player to receive their winnings back in their personal wallet in just a few minutes.
Here, its not always the case every time and that is why there are always scam accusations of delayed withdrawals in a case of withdrawing huge amount after winning such. There is always a review of whether the funds was won the right way while some are locked for security reasons to ensure the platform is not used to launder crypto currency.
Trust
When playing software games such as blackjack, roulette or slot machines, there is no way to verify that the fiat casino is playing fair. As a result the player needs to trust that the odds on display are legitimate.
This is in stark contrast to a cryptocurrency casino that implements a provably fair protocol. Provably fair is supported by the art of cryptography - meaning that each and every gaming outcome can be guaranteed for its fairness. Moreover, this gameplay data cannot be pre-defined or manipulated by the casino.
This is where the issue is because gambling sites that claim to be provably fair are only believed to be so. No authority to actually ensure that this is what is really happening except once in a while that someone took it upon himself to use mathematical equations to test the provability that have been claimed.
