Check with bank factions.

If you find a system then there are plenty of people that would fix you up with a loan.

Just be careful who you ask and how much details you give out about the location.

There are plenty of people who would pay you to slab it for them and then divide up the slabs later.
The closest controlling faction is usually a good bet as they'll probably be the first people to join in on the slabbing.

Does every empty sector have a hidden system? I scanned a whole sector and found nothing...although I may have missed a few spots.

Nope. At some point, perhaps. But currently there's roughly a dozen hidden systems left to find.

How much could you sell a system for.

That is an open ended question. Has too many variables to consider.

What Kendall said. Plus the chances of you finding a system and getting it slabbed before its made public and other factions jump in is next to nothing. Actually the chances of finding a system alone is next to nothing.

Especially since you are competing against Factions that have entire teams scanning for systems

Someone said you fail 99.99 percent. Hes lucky. If there are only 12 systems left the odds of finding one are .0025% meaning you fail 99.9975? of the time. Wowzers forget my small escapade inbetween job shift.

In short, it's not the best option for your get-rich-quickly scheme. Try trading.

Trading has some more complications.(getting stuck with rubbish goods and scamming and discovering your items our docked). Also is there any short of food or drink in this game.
