RS gold operates on a supply and demand service. Due to the release of old school RS and also the announcement of rs3 there is a drop in demand for rs2 gold, so the price drops. Imagine how much bots produce a day, and then think how much will get sold, and then the amount of sold gold that goes back into gold shops. The more money made by bots, the worse the economy will get unless there is an extreme spike in players which lets face it, isn't going to happen.
