Well, I'm not too convinced it is in good hands. Bean wanted to put mansions on captain (a private island that is barely built on). Plus, he tried to get me to sell it by telling a lie about my associate. Time will tell though.
Well theoretically you can bottle xp with slimefun. With flasks of knowledge you can withdraw 1 level of xp into 1 bottle of experience with a Major loss.
This is just not the way for it to be done, especially with the current system. If places like Cayman Bank were to open, this could be possible and be more realistic, but there isn't really need for it.
