Change the device day. Remove automatic date and time from your device and set it forward one day while you are playing. By doing this you will collect 50 diamonds and some bonuses. In the meantime, the factories that produce the materials to upgrade you will fill to capacity. Take everything and put it forward for another day and you can repeat the operation as many times as you want. The important thing is that you always move forward 1 day. The Speed hack works too.
