what's going on on buyer's side? ( scrypt, last two days, mainly on nicehash, not westhash )
there is one bot which places one order for every amount ( 0.23 , 0.24 , 0.25 . 0.26 etc .. ). he always uses a limit of ca 10-13 ghash.. then he sets the limit for high prices to 0.1 ghash.. so he always gets the cheapest hashrate.. if a place an order, i am always overbidden automatially within seconds.. he always invests a maximum of 0.05 btc or so.. and refills it once a minute or so.. as these orders stay for 15 days, he is always the top bidder for every amount...
come on nicehash, this can not be allowed! pleace introduce higher fees for bids / introduce fees for refilling / set an order down in the queue if refilled!
addionally:
during the day often 75% of the scrypt bids get dead simultaneously.. so the price drops to 0.07 or so ( much under value, ltc = 0.22 )
all my pools still work on westhash, but the very same pools on nicehash are shown as "dead"
BUT: the orders of this creepy bot stay active
that can't be a coincidence!
he gets hashrate for 0.07 and i am dead!
so it would be nice, if nicehash would comment on this..
( proof: please check order #122027, #122151 , #122024 , #122149 , #122148, #122022, #122767 , #122020 , #122766 , #122019 , #122010 , #122009 , #112716 , #121358 , #122008 , #121357 )
To mitigate these issues we added another rule in orders sorting:
4th Rule: Changing limit hashing speed to lower value resets your position to the bottom of sub-list of same-priced orders. This rule penalizes low-limit place-holder orders.
