Now that the Credit exchange and Ship Market have been running for some time, I notice a number of, frankly, daft listings seem destined to clutter up the pages for evermore : seriously, 1000 credits for a very early number howker may not be too outrageous, but 9997 for a recent build level 1 howker is just taking the mickey. Barring an outbreak of ridiculously over-funded cretins showing up in the game, (which would be a most happy event for many) such will never find a buyer. Just about every category of ship has a similar range of over-priced offers. 500 credits for a SoW52 ? Cheaper to buy a poor MoW and leave most the guns off it.
Not sure how this silliness can be combated, save by some laborious coding on the devs part to limit the price range you can use : far simpler would be a weekly game-imposed drop in prices listed (say -10% or -1 credit whichever is the greater, a minimum of 1 credit would remain) and force the price down until a bid occurs, which may, of course, drive the price back up to its more realistic level.
The Credit Exchange is also filled with unrealistic bids and offers. Come on folks, nobody is going to sell you 500mil worth of credits for 20gc each, and nobody is going to pay much more than 300k for one either, unless they are manipulating the market for other reasons.
Storing your unused credits in the market with such unlikely prices does little harm : after all, it dont really matter where they are. But we do see 100's of millions in gold coin pretty safely stored in the other side of the market, the 25gc per credit offers, and this is much closer to upsetting the game balance, bypassing bank deposit limits, saving on burials and the costs of moving coin in and out of safety.
That side of the problem does, in my view, warrant addressing.
