a few years ago I was very lucky to invest 250-500 gold and make a profit of 11-13k gold in the trading post.
It was a one-time deal based on a tip from a trusted guild member.
That was three years ago. Since then I haven't invested in anything and only spend money.
Do you have a long-term investment strategy so that I can at least cover my expenditures?
For me it should be safe and take little time. I only play a few hours a month.
Even a net growth of just 1-2% per month would be sufficient for my investment.
