The game is inflated beyond belief.
Starting with devs listening to kiddies screaming about how they need more money, over making combat bonds permanent, to CGs like the Golconda one, where people were able to earn a fleet carrier in a single play session.
There's players out there with hundreds of billions, no matter what feature you bring in to allow to sink cash into, it's going to be broken immediately.
If you have 20 billion and you're thinking "Oh my, would love to be able to buy a megaship, or station, or planet", you must remember that there's thousands of players able to do so, and dozens who could buy like half the bubble.
Inflating a game currency like that is a death spiral, and we can clearly see that the devs lost track of the different values and payouts a long time ago.
Fly to the other end of the galaxy and scan an alien life form in a Lagrange stormcloud for a 50k payout, then go back and oneshot a Thargoid scout for the same amount of cash. Or take part in an unbalanced trading CG making billions in a single day, while some other player hands in his 20 blackboxes for 40k credits.
