It's basically a scam business model.
No sane company is going to give money
away, and that's exactly what it would be doing
by selling you fully managed hashing power that's
profitable.
Duh.
And furthermore, I would say most turnkey mining hardware
sales are scammy too. Sure, you pay electricity,
maintenance, storage,etc..but it doesn't make
sense for a company to sell you gear and give
you any substantial margin when they could mine with it.
Seems like the real winners in mining either
make their own chips or at least buy chips wholesale
and assemble.
...Except it's disingenuous to call it a scam business model.
When you purchase hash power, two main things happen: 1) Yeah, you submit shares and get a reward, but 2) the whole reason for doing so is to secure the network. The business model is providing a service to let you secure the network if you don't know how to do it from home. If a person thinks that there's some magic company with infinite money that will allow any person to give them money and receive more money in return, that's a bit absurd.
I realize you basically said the same thing as I did in my previous sentence, but I think that just places the responsibility back on the consumer rather than on the business. If you make the argument that targeting noobs and others who lack the knowledge to know that the prices are crazy expensive is scamming, then that could also apply to a lot of other similar-looking business models. A good example would be car leasing offers.
Although, I bet we both agree the prices are ludicrous pending significant coin-value increases.
