Give player cash every something seconds

local amount = 5 -- Change this to how much you want the player to have
local timedelay = 4 -- Change this to how long you want the player to suffer and wait
local currency = "Cash" -- Change this to the name of your currency

while wait(timedelay) do -- An alternate is while true do and then the next line is wait(timedelay)
for i, v in pairs(game.Players:GetPlayers()) do
if v:FindFirstChild("leaderstats") then
v.leaderstats[currency].Value = v.leaderstats[currency].Value + amount
