I propose some features to improve the game.
1. Warp time feature that allows to spend satoshis to decrease the cooldown. It could allow people to skill faster and it could allow some additional usage of satoshis. Warp time should be balanced to not be able to use during wars. For example if one has a criminal status he cannot warp time.
2. Allow to borrow some money from the bank for the new players. Make it reputation based. The more GPD reputation you have the more you can borrow. Those satoshis could not be withdrawn from the game. You can hint new players as well to improve your credit rating make new missions for GPD.
3. Make some minigames like gambling or ingame faucet that people can do while they wait for the cooldown. The more faucet the better. Call them like additional jobs to clean up the mess in galactic beurocracy, that was caused by the war with AI or so. You can call them something funny like - captcha office or so lol.
4. Make an auction for a unique expensive items for rich players to auction for. Make it mysterious with some awesome names.
5. Do not allow to invest if you wish, but the premium account should be bought with the invested sathosis. And promote the premium account more that way or so.
6. New unique items does not have to be inventive. Just make energy beam mk 4 or 5 shields mk 2 or 3. And so on and so forth.
