if Steam games have a Summer Sale , G.O. will also have a -50% sale.
In last 2 weeks, operation Hydra pass will be -50 % price off. If now is 5 $ , at the end of operation will be around 2.50 $, a few days.
U can buy as many as U want / U afford. Soon or later U can sell the pass in Community market, or trade it in trading groups.for a better value.for a 5$ -6$ value. If U invest 50$ , U can double your profit.as U buy the pass with 2.50$ and U will sell / trade for a better value.
This is how I made profit, in last 2 years. if U know other tips to make some profit, feel free to share it with us.
