Vault is not suppose to be something that you keep gaining money, it is suppose to be something "if you are a gambler, and you are not currently gambling, you can put it in here" type of deal
Its kinda similar to rakeback that is very common in most sites but the the amount of the 'rakeback' you will get from the vault will be depending on the amount of The Vault and your share of that vault ( percentage of chips you owned ).
I cant fully agree if you say the vault in chips is similar to rakeback in most other sites as it is completely different.
Rakeback is something fixed, calculated based on the rakeback percentage and wagered amount by players while vault in chips is not fixed as the amount will always depending on the vault balance.
Vault may give someone bigger amount than rakeback when the vault balance is big but it may less amount than rakeback when the vault balance is small or even negative.
That's true, plus in rakeback you have to keep gambling to earn money back, whereas if your money is in the vault you just earn something, what you earn changes of course but you earn something, that is the important part. That is why I do not think that it will really be something similar with rakeback, they are totally different. This doesn't mean that rakeback is better or vault is better, they are both good or bad depending on where you are looking at and I do not see any big difference in favorability for me, it is totally the same value for me. Doesn't matter if it is rakeback or vault in the sense that I do not like one more than the other, once again I do agree that they are totally different things, but just because they are different doesn't mean that one is better to me, which is why I do not see any problems with either of them.
