How do I stop a GUI from reseting when a player resets?

So I have a textbutton that uses on click to give 1 point every 3 seconds:

function onClick()
    if game.Players.LocalPlayer.leaderstats.Score.Value >= 100 then
    script.Parent.Visible = false
    while true do
        game.Players.LocalPlayer.leaderstats.Score.Value = game.Players.LocalPlayer.leaderstats.Score.Value + 1
        local str =  game.Players.LocalPlayer.leaderstats.Score.Value
        local str1 = "Your income: "
        game.Players.LocalPlayer.PlayerGui.ScreenGui.Frame.Cashincome.Text = str1..str

wait(3) 
    end
    end
end
script.Parent.MouseButton1Click:connect(onClick)

This works great but when I reset it stops the while loop and makes the GUI visible again. How do I stop it from doing this?
