If you have finished with badging for reds, silvers and yellows etc maybe there should be an option to change them into credits

You haven't seen how much credits you get later on have you?

i have but for example high levels no builder are always neeing credits since there upkeep can got to 20bil+ so they would be searching for credits all day long

Max upkeep is just over 18billion but at high levels your mining "should" cope with this. If not you need to re-evaluate your planet choices and ship build/profession.

If they're in that much need in credits though then they haven't been paying attention to their mining.
For example, as biz said, maximum upkeep is around 18B a day. At that high a rank I estimate that they get around 20-30 billion a day.
Now unless each badge gets you around 5B per badge I think adding this would be a waste. Would be better to simply add new badge items.

Around 25k mining is needed to keep up with upkeep and give you some wiggle room when it comes to colinisation and upgrading planets.

While not this, I would like SOMETHING.

I rest my case.

Be the designated base scanner. You'll burn through them in no time.

Wow, 10 Dark Badges, impressive! If you want, you could always buy the mods, and scrap them for CTP. It's a pathetic rate, but at least your putting them to good use lol
