how can i make different roles in roblox group earn different amount of points?

So i need to make it so that a different role, example: admin, earns a different amount of points in my game. Here is the script I am using,

local amount = 10
local giveTime = 300

while true do
	wait(giveTime)
	for _, plr in pairs(game.Players:GetChildren()) do
		local stats = plr:FindFirstChild('leaderstats')
		if stats then
			stats.Points.Value = stats.Points.Value + amount
		end
	end
end

If anyone can help that would be great!
