I'm sure most of you will have noticed that the amount of auctions atm is crazy, at points it has reached over 1.8 million.
Many of these auctions are unpopular gold players both rare and non rare that are being sold with a max starting price of 150.
A quick technique to make coins is to search for gold players with max start price of 150 and bid 250 on normal gold players and bid 550 on rare gold players. Then simply quick sell them and make instant profit (or wait until an off peak time to re-list them at a higher price).
