After further analysis I'd HIGHLY suggest Nicehash disable their API, implement captchas for making new orders, remove the ability to modify hashpower, disallow people from refilling orders, and increase order cancellation fees to 5-10%.
Maybe you should also HIGHLY suggest to ban multipools (they are an essence of coin difficulty arbitrage) and coin exchange APIs (bots steal good prices!). Also, imagine there are exchanges running arbitrages themselves! This all should be banned!
Yeah, that's what arbitrage does - targets market inefficiencies and destroys them. You will have live with it.
(I am not running arbitrages of any kind myself).
Multipools can't be manipualted the way NH is being manipulated right now. They're two completely different things. Exchange API bots are here to stay, unfortunately, NH however is the only game that does what they do with the supported algos. This would be better if they were a multipool.
NH can stop this. Don't act like they can't. There aren't a dozen or so NH's floating around with the same amount of hashing power. NH is the only game in town and hashing power is a finite resource. It's all starting to pool here, if you don't kill off arbitrage the miners will go under as they'll push the prices down to power break even/shutdown for miners. Then no one wins, except the 2-3 people running arbitrage bots on NH right now.
As explained several times before already, we will not interfere with market in any kind.
You're already interfering with the market by allowing arbitrage bots into miner territory! Miners could actually profit off protocols, now you're gathering them all up and executing them. This isn't 'organic' and this sort of market didn't even exist before NH showed up. This isn't the same as rental pools such as MMR. MMR doesn't allow automated rentals and doesn't just feed out hashrate to bots.
Allowing a handful of people to complete rape the market is like willfully trying to destroy it and don't pretend this is natural and orderly. This didn't even exist up till recently and you're allowing them to manipulate your system to further destroy the market.
I don't understand where the lack of interference comes from either. I didn't say NH should be shut down, but BOTS, non-human entities that automatically push humans out of the market should be eliminated. You have all these rules setup when people setup their orders to try to make the system seem 'fair', you even talk about how Westhash exists so we don't get cheated out of a few fraction of hashing power, but then you allow them to completely manipulate, knowingly let them manipulate the market, which completely wrecks the whole thing.
Earlier tonight there were placeholder orders on .2 through .3, where one person was controlling all the hashrate. He'd top up his orders when they were low, so people wouldn't end up underneath. Eventually people simply canceled their orders, the price would drop through all the ranks of his orders as they set them to .05 GH of power, and then the bottom order above the next highest that wasn't them would be set to infinite or a really high number. This was on Nicehash too, Westhash has the same guy completely controlling x15 I mentioned last week.
I think you're confusing regulation for blatant exploitation of miners and buyers by automated entities. How is making a human set up orders regulating the market anyway? That's the way it's done in the first place. Making a penalty for people trying to cancel orders also encourage people to ride things out. Disallowing people from changing their hashrate prevents placeholder orders which are being used to push people out of the market (which otherwise would increase prices). There is even a bit about placeholders in the FAQ, yet it's broken and placeholders still exist.
