It your account and you fix whatever price you want. But if you want to get a bid then you should consider what other members are suggesting. Those price suggestions are not fully correct and those are based on formulas. But for buyers you should consider to give an attractive price then you may get bids. Good luck to you..
You have still a point though but potential hero member on 0.1 is decent enough though hence collecting potential points in a longer period of time isnt easy at all. I suppose this account being sale is a farmed account for sure. If OP want 0.1 price then we couldnt do anything about it.
