In skyblock we all, or at least some of us, strive for the most amount of money. In solo this is just fine with your own 'Skyblock coins' in the scoreboard. But in co-op, you don't really have an idea how much money the island really owns. And on top of that, again in co-op, if your friends and you are going for a really expensive spawner/generator/… one of the x persons on the island has to get all the money as you can't share the money. So I propose a 'Skyblock Island bank/vault' where the entire island has access to. This is of course without removing your own coin 'bank'.
