Hi, Phil.

This is no mystery order, take a look at the bottom of the orders list: there is a link to FAQ with explanation. We marked it explicitly since we want to provide absolutely transparent service.

Additional information: As you know, NiceHash/WestHash doesn't have it's own hashing power, it completely relies on hashing power sellers. And of course, sellers are not interested in selling hashing power below a certain level of profitability (currently -8%) - we've received several feedback from miners with these concerns. Therefore to sustain a long-term relationship with miners (sellers) we have to provide them at least a decent sustainable price. Otherwise miners (sellers) will go away and there will be no hash to buy whatsoever, or when hash power will be too small prices will go higher. Hopefully you understand this.

It is of no intention for us to make any money with arbitrage orders (since we're not running our own Bitcoin mining pools we have to point arbitrage order to external pools and taking into account variance and external pool fees, therefore arbitrage order will always basically generate us a 0 profit).

Anyway, this might not be our final decision, we're testing out this approach, but we have to find a way for long-term balance between sellers & miners expectations.

Of course, as always, comments are welcome, from both sellers and buyers.

Thank you for using our service!
