How to give players through the server money at the end of each wave?

Hey! I've been trying to make td game for a while now and my friends keep telling me to implement money after each round. I've tried and tried and since my money system runs on the server, not the client, I can't just say game.Players.LocalPlayer.Gold.Value += 200. This is very annoying and I need someone to help please! I'll leave all my code down below.

The serverscript handling the money:

game.ReplicatedStorage.Events.GiverCash.OnServerEvent:Connect(function()
    for i,de in ipairs(game.Players:GetChildren()) do
        if game.Workspace.Ready.Value == true then
            de.Gold.Value += 200
            game.Workspace.Ready.Value = false
        else
            warn("Ready value isn't true")
        end
    end
end)

The localscript firing the event

while true do
    wait(0.1)
    if workspace.Ready.Value == true then
        game.ReplicatedStorage.Events.GiverCash:FireServer(game.Players)
    end
end

The serverscript handling the round system and setting the value to true after each round:

local SS = game:GetService("ServerStorage")


local mob = require(script.Mob)
local tower = require(script.Tower)
local map = workspace.Baselands

local info = workspace.Info
local gameOver = false

map.Base.Humanoid.HealthChanged:Connect(function(health)
    if health <= 0 then
        gameOver = true
    end
end)



wait(5)
for i=15, 0, -1 do
    info.Message.Value = "Game starting in..." .. i
    task.wait(1)
end

for wave=1, 15 do
    info.Wave.Value = wave
    info.Message.Value = ""

    workspace.Ready.Value = true

    if wave <= 2 then
        mob.Spawn("Zombie", 3 * wave, map)
    elseif wave <= 4 then
        for i=1, 3 do
            mob.Spawn("Zombie", wave, map)
            mob.Spawn("Noob", wave, map)
        end
    elseif wave <= 7 then
        for i=1, 3 do
            mob.Spawn("Zombie", wave, map)
            mob.Spawn("Noob", wave, map)
            mob.Spawn("Mech", 2 * (wave * 0.5), map)
        end
    elseif wave <= 9 then
        mob.Spawn("Mech", 2 * wave, map)
        mob.Spawn("Noob", wave, map)
        for i=1, 2 do
            mob.Spawn("Zombie", (wave * 0.5), map)
            mob.Spawn("Mech", (wave * 0.5), map)
        end
        mob.Spawn("Teddy", 1, map)
    elseif wave <= 10 then
        mob.Spawn("Zombie", 40, map)
        for i=1, 2 do 
            mob.Spawn("Zombie", 2, map)
            mob.Spawn("Mech", 5, map)
            mob.Spawn("Teddy", 1, map)
        end
        mob.Spawn("Teddy", 10, map)
    elseif wave <= 11 then
        for i=1, 3 do
            mob.Spawn("Shock", wave, map)
            mob.Spawn("Teddy", wave, map)
            mob.Spawn("Mech", wave, map)
        end
    elseif wave <= 12 then
        for i=1, 2 do
        mob.Spawn("Shock", 2 * wave, map)
        mob.Spawn("HardShock", 7, map)
            mob.Spawn("Teddy", 3 * wave, map)
        end
    elseif wave <= 14 then
        for i=1, 2 do
            mob.Spawn("Shock", 2 * wave, map)
            mob.Spawn("HardShock", 7, map)
            mob.Spawn("Tedyy", 10, map)
            mob.Spawn("Molten", 5, map)
        end
    elseif wave == 15 then
        mob.Spawn("Shock", 5 * wave, map)
        mob.Spawn("HardShock", 2 * wave, map)
        mob.Spawn("Molten", 10, map)
        mob.Spawn("SpeedyMolten", 4, map)
        mob.Spawn("MoltenBoss", 1, map)
    end

    repeat
        task.wait(1)
    until #workspace.Mobs:GetChildren() == 0 or gameOver

    if gameOver then
        info.Message.Value = "Game Over"
        break
    end

    for i=5, 0, -1 do
        info.Message.Value = "Next wave starting in..." .. i
        task.wait(1)
    end
end
