The orders go up and down exactly 23-24$ from the current price in 3cents intervals. So there should be around 600 bids and 600 asks. This is the work of a bot. But I don't really see a sense behind this.
Can somebody explain to me why exchanges chart a relativ amount of fee and not a fixed amount (+ relative)?
With Bitcoins divisibility, you need to be able to buy/sell pieces of a coin, so you can't charge a flat fee because then it would cost 7 or 10 or $24 to buy/sell .01 BTC. That would be ridiculous. So for smaller orders, a percentage based fee is much better. On the other hand, the fee is higher than your typical stock brokerage for a large order.
I see it that way: Like on the block chain every transaction cost the same ressources. Ok, you have to consider outputs. If you buy up 100 tiny 5$ sell orders this requires more ressources than to buy up one 500$ sell order. But this is not the fault of the buyer.
I can understand the problem that you would have a higher fee on small volume transactions. But this is intended. This is the same with every transaction service in the world. You could make on Bitstamp 1$ dollar fee(or let's say 50cent) plus 0.15%. This would prevent all these tiny bids and asks and is not a problem for long term buyers of relative small amounts (100$) and no problem of real day traders (volume above 200-300$ per trade, I would guess).
Break even would be at 0.5 + x*0.0015 = x*0.002 -> $1000
Edit: So no, 5$ per trade is way to much. 50Cent or 1$ are enough. (or 30Cent)
