By the way, you asked about benefits that justify the premium on MRR. As a rig owner, I have the ability to remotely manage my gear on MRR. I can setup profiles to quickly move my hash from coin to coin and pool to pool. As a renter on MRR, I can evaluate the available gear and decide whether or not I wish to rent it based on scores, average hash rate, location, etc.
As a miner: using MRR as a gear manager only adds up extra latency to your target pool which results in more stale shares. There are plenty of rig managing software solutions, even for free - local proxies, or no? How is extra latency added a benefit, we cannot understand.
As a buyer: on NH/WH you don't have to evaluate available gear, because you always get only 100% verified shares and always pay only for speed that was sent to you. On MRR you loose time, because you need to do evaluation of ratings. Besides, if rig does not perform well, you need to fill in ticket (means extra time). Aditionally, at MRR you cannot cancel contract. At NH/WH you can cancel any time.
Considering all these facts, we don't see any premium features at MRR - the reality is opposite - NH/WH offers premium features over all other renting services.
But lets keep this discussion open - let us know what features would you like to see added to NH/WH. We have some cool never-seen stuff planned, but let's hear community now.
As a gear ownerUsing any mining rental site will add latency. You can't state that MRR does, but you do not. That's simply a false statement. For example, if I choose to use WH, I have to point my gear to your pool. When my gear is rented, it's still pointed (at least from my end) to your pool. You are redirecting the traffic from there to whatever pool the renter has chosen for his order.
When my gear is not rented, my gear is pointed to whatever backup pool I've set. With any BitmainTech miner, I've only got 3 pools I can configure via their web interface. If I'm using WH/NH, 2 of the three slots are taken. Therefore, I've only got a single pool to which I can point my miners if/when my gear isn't rented. If that pool happens to go down, my miners are idle. That's unacceptable.
With MRR, I have the option to set up to 5 pools that my miner can point to. So, I can set my miners to connect to MRR's servers and still have two possible backups that my gear will fail over to. Further, I can easily change to which pools my gear is pointing with the click of a button from anywhere. I can do it while I'm sitting at an airport waiting for my flight. I can do it from the hotel. Wherever I want. And, I don't have to setup any kind of proxy server at my home and expose that. The convenience of being able to easily remotely monitor my gear and change things on a whim by clicking a button is a far better level of service offered by MRR.
As a gear renterWith MRR, I have the ability to see exactly from where my hashing is being sourced. If I'm going to mine on a pool that's on the east coast of the US, I don't want gear in China providing the hash because I'm going to have to deal with the latency of hash coming halfway across the planet. I can also see descriptions of the rigs that will be providing my hash, so I'll know that if, for example, I want to mine on p2pool, I won't pick any Neptune or S2s or Avalon tubes because they either flat out don't work with p2pool or hash at lower-than-advertised rates.
Further, and this is in regards to canceling a rental, sure, you can cancel a rental on WH/NH at any time. Your rental can also be stopped at any time because somebody decided to pay more than you did, so the gear that was hashing for you is now hashing for somebody else. With MRR, you've got a contract for a specified time. That gear is yours. If I rent gear for a week, I want that gear to be under my control for a week, not wonder if it'll mine for 3 days and then stop and maybe pick back up again 5 days later.
