20x is very likeable as a wagering requirement and near to the current standard that's being asked for 30x. Beyond 60x could be too much and I think everyone is already aching if it's around 50x. So these are the estimates that everyone might think of the numbers given by the casinos as their wagering requirement. I remember at time that there's this 90x or 100x just for withdrawal to fill in the requirement. I guess that's too much but when we're too determined to do that, it can be done but at our expense.
Unfortunately, casino will not give us the option to choose what percentage or x of wager requirement we would be comfortable with when they give or want to offer us a bonus, so all that we are actually discussing here is nothing but for discussion sake.
Casinos don't give a general bonus without attaching some strings to it, it's not but a business which they plan to make profit from as well, so when ever a casino launches a bonus that any body can take advantage of, rest assured that what ever percentage they are going to place the wager requirement is one they have calculated well and are very sure it's going to benefit them more than it should benefit any gambler except it's a situation where the gambler is or was extremely lucky.
So, I think if we find a way to really understand this, it will help us as gamblers to know when and which bonus to say no to, cus not every casino bonuses come with good motive from the casino.
