The merchants only takes very small amounts like 1-10 while you have 1m+ Items to sell. So it's hard to get that awesome 2min 15% speed boost. (useless)
The gambling is really great, every game that should help make money after heads or tails has a 90%-98% chance you loose, mind you those are not even the ones with the warning on them that they can loose. Once you fully upgrade them it's still nearly impossible to make money.
The fracture is done really fast, just upgrade dmg since that gets doubled per level while the other upgrades give like 2% per level.
After that is the drone workshop, you get a helper that only asks for more drones because 95% are used to drive resources around while the workshop is full and can't work because only 1 drone is removing stuff from the output. So your output is always blocking the everything else.
