How can I transform my leaderstats script?

I have a basic leaderstats script. I want to modify it to save things that are not numbers and not in leaderstats. How can I do that?

Script:

local dataStore = game:GetService("DataStoreService"):GetDataStore("MoneyData") -- MoneyData is the name of the DataStore.Change it to reset all data.
StarterMoney = 50 -- This is the amount of money new players will have

game.Players.PlayerAdded:Connect(function(player)
	local leaderstats = Instance.new("Folder")
	leaderstats.Name = "leaderstats" -- DO NOT CHANGE THIS NAME.PLEASE!
	leaderstats.Parent = player
	
	local Currency = Instance.new("IntValue")
	Currency.Name = "Money" -- Change "Money" to whatever your currency is named"
	Currency.Parent = leaderstats
	Currency.Value = dataStore:GetAsync(player.UserId) or StarterMoney
	
	while true do
		wait(math.random(2,3))
		Currency.Value = Currency.Value+math.random(1,4)
	end
end)
game.Players.PlayerRemoving:Connect(function(player)
	dataStore:SetAsync(player.UserId, player.leaderstats.Money.Value)
end)

PS. The script is in ServerScriptService and I want the script to be in the same script.
