They need to get rid of the ability to change requested GH as well. This is silly, there is an entire column of place holders right now on x15 operating at .05 GH when a hour ago they were operating at infinite or 4GH. This really fucks with the difficulty on coins as someone has obviously wrote a easy auto-script to decrease GH at a certain price when difficulty goes up. Why is there even a API allowed for Nicehash? It just encourages manipulation and completely flat lines the market, much like microtransactions/arbitrage for normal coins. There is no investment here, it's just scripts wrecking prices.
And Posting this again:
There really needs to be more crossover between nicehash and westhash pools. Over the last week or so there has been one buyer running a script or spending a butt ton of time pushing everyone out of the x15 market simply by constantly changing their order and out bidding other people. Since there is so few miners on westhash, orders below them never get filled and despite their order having relatively little amount of bitcoin (to reduce cancellation fees) and ghash (so they only take the miners and not extra by having the pool auto-switch to them as most profitable) they can control the market. As soon as the other order leaves the market, they drop theirs down again. It starts all over again.
I assume it's automated as it seems to be going pretty much steady as long as I've watched the x15 market. This isn't good for nicehash, miners, or buyers.
I understand the idea of 'efficiency' by separating geographic locations, but I've been buying on nicehash using NA pools and it doesn't make THAT much of a difference. Since Nicehash is cloud based, it's entirely possible to sort miners based on their geographic location and appropriate them for a pool close to their location completely transparently to the buyers and the miners (such as a quick ping to the miner and the pool from two or three different geographic locations would locate the address approximately or with a IP lookup). Obviously there would be some cross-over, but since prices are already the same for both nicehash and westhash, it doesn't matter.
Whoever it is, is devastating the market though and solely controlling it. That obviously also influences prices on Nicehash.
I've read the 'reasoning' given already and the tiny little differences in prices due to going over the oceans is downright silly. When you have people wrecking the entire economy and you complain about a little bit of efficiency loss because your OCD demands it, it doesn't help anyone out. As I outlined above, the pools could take care of most of the differences between geographic locations by intelligently allocating miners to orders with a bit of automation behind the scenes. The rest would be a wash, but it wouldn't amount to anything significant.
Due to the amount of hashing power nicehash has under its thumb, the consequences of what is happening here are far reaching. It affects every algo nicehash supports, which luckily still excludes some profitable algos (for miners).
