  • Set the bidding amount of a weapon as low as 700 M for normal or rare weapons. If the weapon is in high demand, you may get until 1000 M for bidding.
  • If nobody bids for 700 M, it's better for you to disassemble it to get 500 M.
  • Never put the bidding price over 1000 M for normal weapons since nobody's gonna buy it.
  • For epic weapons, 1000 M ~ 5000 M is a good start bid, depending on the weapon. Never set the Direct Buy price close to Bidding Price.
