how to give a player 1 point after every 60 seconds?

while(wait(60)) do
    points = points + 1
end

Change "points" to whatever variable or instance that's storing points for whatever player you're looking for. You could put this in a script and parent that script to a specific player and find the points value based on that parent player.

Your script has some minor issues like some typos Make sure these are in the serverscriptservice:

Leaderboard script:

game.Players.PlayerAdded:Connect(function(plr)
    local stats = Instance.new("Folder",plr)
    stats.Name = "leaderstats"
    local money = Instance.new("IntValue",stats)
    money.Name = "Money"
    money.Value = 0
while wait(3) do -- change this to whatever time you want
money.Value = money.Value + 60
end
end)

Datastore script:

local DATA_STORE_NAME = "Config"
local DATA_STORE_SCOPE = "MyGameName"
local KEY_NEW_FEATURE = "NewFeatureEnabled"

local DataStoreService = game:GetService("DataStoreService")

local dsConfig = DataStoreService:GetDataStore(DATA_STORE_NAME, DATA_STORE_SCOPE)

local function checkFeature()
    local isFeatureEnabled
    local success, err = pcall(function()
        isFeatureEnabled = dsConfig:GetAsync(KEY_NEW_FEATURE)
    end)
    if success then
        print(KEY_NEW_FEATURE .. ": " .. tostring(isFeatureEnabled))
        if isFeatureEnabled == true then
            print("Feature is enabled!")
        elseif isFeatureEnabled == false then
            print("Feature is disabled!")
        elseif isFeatureEnabled == nil then
            print("Feature is not set!")
        else
            -- Some other value was found in this key
        end
    else
        print("Failed to load feature! Error: " .. tostring(err))
    end
    return success
end

local function onFeatureChanged(isFeatureEnabled)
    print("Feature toggled: " .. tostring(isFeatureEnabled))
end

-- Listen for changes
dsConfig:OnUpdate(KEY_NEW_FEATURE, onFeatureChanged)

local function setFeatureEnabled(isFeatureEnabled)
    local success, err = pcall(function()
        dsConfig:SetAsync(KEY_NEW_FEATURE, isFeatureEnabled)
    end) 
    return success
end

setFeatureEnabled(true)
checkFeature()
