How do i save leaderstats for every game?

Hello, I have set up a system with money. Now I can't seem to figure out how to save the money in the cloud, so the player can join any game, with the same amount of money that he had before.

How I set up the money leaderstat thingy

game.Players.PlayerAdded:connect(function(player)
 local folder = Instance.new("Folder",player)
 folder.Name = "leaderstats"
 local currency1 = Instance.new("IntValue",folder)
 currency1.Name = "Cash"
