Instadebit casinos will give players a casino bonus when they use this funding method to add credits to there casino accounts. It is a simple way to purchase credits where the limits can vary depending on the online casino you play at.
For normal users they do have a standard max amount which you can deposit using instadebit but VIP players may have higher limits as the online casino can raise your limit at that certain casino. Some give as much as 10k per day worth of deposits. If you want higher limits contact the online casino support in which you play at.
The bonuses you may get will vary from one place to another as they all do not have a set standard. Often they will give specials on days of the month to boost up purchases in the casino so you will want to log in often to see if they have a new offer to opt for. Most users do like the extra bonus you can get when using different wallets to purchase with but you may also want to look at just a purchase offer that they are giving that will have nothing to do with methods. At times they are much better than a 10% that you might get otherwise.
