I ask you to always keep proof of your deposits when using any online casino. This shouldn’t be only for high rollers but also to those who deposit small amounts, because you never know when you get lucky and win an amount where the casino refuses to pay you out.
I suppose this will also be useful for proving the origin of the funds to the tax authorities, as I suspect these guys will want to get their hands on your hard-earned gambling money.

Let’s make it a habit to save a screenshot or copy the Tx Id of every deposit, and also your account history page. Ive seen many cases where players couldn’t file a proper complaint on platforms such as AskGamblers or even be taken seriously in the forum, simply because they lacked evidence especially after their account was closed.
You have proposed a good initiative, because there is no "card" weaker than an attempt to prove one's case without having "strong" evidence to do so.
I think its a good idea to create a folder or document to store this data. You never know when you might need it. For example, a casino may wrongly accuse you of something and lock your account without warning, not able to remember or provide any evidence.
Is it simply a mistake for a casino to accuse you and block your account? Or is it done deliberately to avoid paying out winnings to the "lucky ones"? Because the casino has more power in this situation.
If anyone has better tips or more methods for keeping records feel free to share them…
Maybe just shouldn't "play" against someone who has a "joker" (or 2 at once) hidden up their sleeve?
