A wait until function?(still needs help)

So I have a script where a coin gives you one coin then destroys. Is there any way you can use something like a wait until function to do wait until part1 is destroyed then let the person be able to collect part2?

Ok, erm so what I'm going to say is gonna sound stupid in a way but it'll work.

So in order to do this you do:

while true do
if game.Workspace:FindFirstChild("part1") == nil then
game.Workspace.part2.Touched:connect(function()
[put whatever code you wanted here]
end)
break
end
wait()
end

I did this

while true do
if game.Workspace:FindFirstChild("part1") == nil then
game.Workspace.part2.Touched:connect(function()
script.Parent.Touched:connect(function(part)
	if game.Players:findFirstChild(part.Parent.Name) then
		local plr = game.Players:findFirstChild(part.Parent.Name)
		plr.leaderstats.Coins.Value = plr.leaderstats.Coins.Value + 1
	end
end)
local debounce = true
script.Parent.Touched:connect(function(part)
	if debounce then
		debounce = false
		if game.Players:findFirstChild(part.Parent.Name) then
			local plr = game.Players:findFirstChild(part.Parent.Name)
			plr.leaderstats.Coins.Value = plr.leaderstats.Coins.Value
+1
			script.Parent:destroy()
		end
	end
end)
end)
break
end
wait()
end

I don't know how to fix it
