Im not sure if its worth to buy a Mercury device ?
Why not? They all return at the same ratio.
No they obviously dont.
Mercury means higher price per GH.
Couple hundred bucks. It's barely a difference.
$200 per device, plus 2-4x shipping depending on what device you wish to mirror, plus your elec.
Is that more affordable than hosting?
Your device hosted presumably is fixed on site immediately if faulty so minimal downtime and no shipping costs going back and fourth.
Go on then, I have to ask. How do they immediately get them up and running? There is no way that can happen.
For example, mine will be sent next day delivery (what I paid for anyway) ...so unless they're hosting them at the factory they should get onsite about the same time, or later if they are efficient and send batches.
When mine arrives onsite it will be unboxed and I'll not stop until it]s hashing...there won't be 400 other machines sitting there awaiting my attention which is exactly what's going to happen at the other end with hosted machines. I won't go home for tea at 5pm and sort the rest out the next day either. Unless they have a hell of a lot of staff working 23/7 a lot of rigs will sit around a while waiting to be set up. IT's 1/1 human to rig when mine comes. When stuff breaks and no customer's there it rarely gets immediate attention in my experience, although it's going to be much easier and faster to get it back up hosted than offsite for sure.
Hosting is expensive, these machines will be old in 6 months...maybe not even earning their power bill. You have to consider what you'll do then. Assuming you probably have a next gen if all goes to KnC plan. Continue to pay hosting (for both)? Have it sent to you? Neither great options when it's not producing much. Scrap it? Ebay it? Set it to another task? Maybe another currency?
Nothing is as straightforward as it would appear. Always we need to make a best guess.
