Knowing the future is knowing your past and present.
Read your daily news and be on alert and ready with funds to purchase domains on forums.
Knowing what to buy is important. Read through the Marketplace boards for the past 6-18 months, focus on the prices and what is selling and what is flopping!
The most important thing you need to know, is knowing that Domaining is for long term investors.
Short-Term investments are based on few factors.
1. Getting lucky (the owner of iphone_com settled for few millions)
2. Flipping domains every 2-12 months.
3. Buying expired domains and selling them for 50%-150% profit fast.
the list goes on..
The point is, know what's selling now, what sold in the past, and what will sell next!
Spend a good 3-6 months observing.
