Only people who have a lot of money can achieve it, but it depends on their willingness to lose all the money.
We as gamblers, also have to think about whether it is worth doing because something impossible can never be achieved for small gamblers like us.
But it seems that the casino will not lift this limit because it should have been that casinos did not use high limits on their users.
After all, it could make users uncomfortable playing there.
The way out of this is to never deposit into such a casino and rather find another one that doesn't have such high wagering requirements that you shouldn't have any trouble getting there.
It has nothing to do with how much money we have in our pocket when it comes to wagering requirement for deposit because basically the more deposit you make, the higher wager you need to do.
So even if you have a lot of money, it does not a guarantee that you will be able to achieve the wagering requirement.
Your last suggestion is the best thing should be done by all gamblers regardless how big/small gamblers we are, choose the casinos with low wagering requirement for normal deposit.
