Your cut-off line for withdrawals from online casinos should be in respect to the amount in the account and not over ten thousand at any given time especially not closer than 24 hours together. There are several reasons for this but the biggest reason for not taking everything out of your casino account is if the casino is planning on cheating you this is the time to do it. Take half out though and they may decide to pay you expecting that you will lose the other half back to the casino which is a loss that they are willing to take in order to keep a player of your proven status. It really depends on your past proven playing history how much you can get away with taking out and not losing the casino's interest in keeping the relationship in good standing.
I would suggest when taking out that you get one withdrawal well through the casino process before starting the next one. Online casinos know that any transfer of currency over ten thousand on a given day from any one entity will require investigation from the US authorities and since they know that will happen they first do their own investigation which automatically will require proof of identity from the player such as a fax of both sides of your drivers license, a copy of a recent utility bill as proof of residency (where you live) and in some cases a copy of the card that was used to deposit into the casino. So keep those withdrawals under ten grand and you should be okay at the online casinos although keep in mind they randomly check every withdrawal request and if your number comes up there is no getting around sending in the requested information short of not getting your money out of the account.
I've done this process and withdrew money from hundreds of online casinos and IF they truly planned on paying me I have never had any problems arise from sending them my information. And much of that was back in the days when you could use credit cards to deposit and I never had any unauthorized charges to my account, nor have had any reason due to online gambling to cancel a credit or debit card. Of course I have taken the necessary precautions to protect my bank account by acquiring an ewallet online banking solution so that the only private information I am giving out is leading back to the ewallet and not to my more affluent banking account at my brick and mortar bank. As already mentioned I am careful about how I access my online account.
