... this is disappointing and a tad bit concerning.
Sadly I have to admit I get the same impression.
You shouldn't be concerned or sad about the hosting plan. They could have not offered one and if you have a better/cheaper way of hosting just do not purchase it.
Some people will find that it is a better solution for them and that's that.
Actually, if you go to their "About Us" page, they talk about how the hosting/renting options are one of the reasons why they stand out from the competition:
https://www.kncminer.com/pages/aboutus" Imagine if you could rent your mining machine or a quarter of a machine instead of buying it. Then you could get started with less money and you could easily upgrade whenever it suits you. You would then not have to bother about all technical issues to set up your own machine and you have it fixed sooner if anything [breaks].
Imagine if you could actually decide what Hash-rate you would like to use for the next period and only pay for that.
Or, if you already into this game you probably would like to own your own high performance machine, but you rather have it in a datacenter with high security and proper air conditioner, avoid your own electricity cost and assure you are up and running the day after your purchase of your product."
Plus, I think hosting with KNC is a safe way to ensure the product will work in the first 6-12 months and if something breaks, they'll be able to fix it onsite. It's almost like an extended warranty.
For many of us, a Jupiter on its own is already a large/risky investment. And having to fork up another large sum of money for upfront hosting is disappointing. I think many people agree that any investor in ASICs should be prepared to risk losing it all. I'd be more accepting if I lost $7k for a failed/indefinite ASIC Jupiter experiment, but losing another $2-3k to a hosting package is too much. I hope if enough people demand a month-to-month option, that they'll open it up.
