So far, whale casino is the most popular on telegram casinos as far as I know, and it's only a while they started operating, so, I believe it's too early to begin to think that they would really want to get into any trouble with any customer which could daint or worst still, damage the reputation they are currently building.
I've played on this casino in previous times and had no issues with withdrawals, though my withdrawal amount was way less, but still, it came through all successfully all the time I requested one.
So, I believe the cancelation of the user's withdrawal request isnt something to worry about, like you said, it happens often times when traffic is high, maybe the system is built and programmed to automatically take such action in such circumstances, which is understandable, so let's hope the request will be successfully completed on this second trial.
New casino will not want to damage their reputation because that can impact to their business in the long run. They will maintain their reputation to be better so they can grow their casino among the other casinos. And when the casino ask him to try to withdraw again, that means they care with their members and suggest to try. If everything is okay, he will receive his money without taking too long. We do not know when the traffic is high or low so we must make sure that when we want to withdraw our money, the traffic is not too high so we will not have to wait for long.
I was able login and really create an account this time
However, when I just logged I was requested many sensitive data.
---
My suggestion would be to disable those required fields, unless you want to verify the account...
I understand there could be some legal obligations, but I have used a lot of other casinos and I wasn't forced to give all that information.
Whenever I use Whale on Telegram, that box also pops out as well.
TBH, I have doubts on whether I will put my personal information on it or not especially they are asking some sensitive information like you said.
I wonder why the Whale team asks when you're just logging in when you can just give your personal information to them if you're withdrawing huge amounts of money like what other online casinos are doing. I second the suggestion though or maybe put an "Optional" option beside it, or just completely remove it and ask it when withdrawing certain amounts of money.
Maybe they want just to make sure that we really want to use their casino. They want to know who can do the basic KYC in their casino. so they ask us to fills the registration with some personal data. It is up to you whether you want to give it or waiting for the next update. Maybe waiting for the next announcement will be better so we know what is happen. But what we see is the basic KYC that we must fills.
