I'm pretty sure it's not possible. Back when I started, I sweated until I made 5 ped, then shot stuff, repeat. If I broke even, I did a 2nd run. Took like 4 months to max an opalo this way. I don't believe I made a profit hunting until I found some SuUuUUuper secret mobs that regularly gave high MU items, but when the MU on those dropped, it wasn't worth it anymore. I also did well in the land explosion a few years ago with the daily/monthly tournaments.
Random advice:
Go to entropiawiki and look at the various weapon types, sort by DPS. Pick one endgame weapon and only use that weapon type forever. If you spread your skills too thin, you'll take that much longer to skill up. In general, it is agreed that the best weapons in the game are the EWE-EP Mercenary Modified (Mod Merc, or MM, laser pistol,) the DOA series (BLP rifle/carbine) and IMP2k (forget the full name, something something mark 2 improved, laser carbine.)
Deposit enough to get Gremlin armor, later get 2A plates, then 5B plates. Whatever you do, do not get the manufactured armor available in shops, especially ghost or phantom. Decay on ghost and phantom will run you into the poor house twice as fast. Pixie is generally recommended for newbies, but remember that protection decreases with decay.
Get a combat fap and a resting fap. The combat fap generally heals faster and more hps with higher decay, while the resting faps are generally slower with less hp but higher heal per pec. As a general rule, combat faps tend to look like first aid kits while resting faps tend to look like pokemon balls.
Use a finisher. I used to use the TT pistol, but changed to the TT sword to gain strength. You want to be able to carry at least 150-200kg. When you feel you have enough strength, use the opalo or something similar to finish off monsters.
Don't try to get fancy. The most eco monster to kill are chirpies, because you take zero damage and zero armor decay. However, you also gain zero evade, courage, etc. It is incredibly vital to raise evade. If you have extra money to depo, it is virtually unanimous to put it into evade rather than upgrade your armor/fap/wep etc.
If you are team hunting, a VTOL is your best friend. If somebody is getting beat up or runs out of ammo, just jump into the ship.
Spacing: you can reduce the amount of damage you take in teams by spacing out. The best team I was ever in was 3 of us vs the original prots. We made a widely spaced triangle, and the prot would spend about 50% of it's time running between us. Whoever was getting attacked just started fapping while the other two kept shooting.
This might seem like a no brainer, but make sure you team with someone you trust and you have pre-agreed rules about loot splits. Items will not be fairly split by the computer. The one that worked best for me was that all items would be split by TT value equally among all team members that participated in the loot. Because I usually did the majority of the damage anyway, I would take 50% of the MU as a finder's fee, and split the rest. For example, we found a pistol once with an MU of 110%, I calculated it at 105% and split it evenly. For ESI's, we split it based on -100% of daily MU to cover auction fees of the seller, so a 10 ped ESI at 600% would be split as 500%.
