That type of sharing could be amazing for some people or could be horrible for some others. If you have a clan that plays the same way, like group of people who love martingale on dice let's say, they can build a clan called "martingaledice clan" or whatever, and they can pool their resources together and gamble that way, even automatically, and even if they lose their money, they would end up with a bigger return considering the bigger wager.
So, it's good if you could get all the people who think the same way together, it would be a smart decision. However, if you end up getting people who are not working together very well, then it's going to be a problem.
There are different clans which you can join or if you don't like any of them you can create one of your own to gather some like minded gamblers but it's not like everyone is gambling in the clan and only one person will gamble on your behalf and you could have discussion as well in the clan chat to make some strategies on how to gamble if you wish to do so otherwise play solo as regular gambling.There is free choice to leave anytime and get your funds back so no need to worry as you are not into signing some contract that will lock your fund in clan pool.
