I totally agree with Kano and his detailed mathematical analysis of the nerdminer.
Any online calculator will tell you the same thing, it isn't rocket science, anyone with a few brain cells knows what are the chances of hitting a block with such hashrate, in fact, even with those GH range miners your chances are slim to nothing, even using the BM1366 chip we are talking about 1 in 760,000,000 chances per block, in other words, 15,000 years, that's indeed a lot less than the 130,000,000,000 years needed by 50KH miner, but arguably even the 0.5GH is a waste of time and money.
Nerdminer is a concept that is good, the ability to control ASICs such as BM1397 is in the pipeline, you could argue that nobody no should be mining with 50KH miner which I have said myself dozen times, but you can't dismiss the whole project and accuse it of being a virus or accuse the devs behind of being cons who "sell" products that don't work, it's open source people do whatever the hell they want with it, if I manage to flash Cgminer to my 10$ calculator and use that to mine
BTC -- it doesn't make Cgminer stupid.
Take home message is that the Nerdminer and Bitaxe, are completely different opensource projects. They should not be clubbed together and cause confusion.
Why not? both are open-source mining projects, slightly different concepts, and largely different hashrates "at the moment" but that doesn't mean they shouldn't be clubbed together.
See I don't even advocate using industrial-grade miners at home, I think mining "treated as a business" needs to be done at an industrial level, a separate building/farm with dedicated industrial ASICs miners, anything short of that is either gambling, learning or a hobby, yes that makes no profit, you probably lose more than what you will ever earn, but doesn't make people who use it stupid, it also doesn't make people who make those projects scammers.
I can bring forward a dozen people who know their chances of hitting a block are next to nothing yet they do it for fun, How many people can you bring forward to claim that they are certain of hitting the block with 50kh/s? It's naive to assume that everyone else is stupid, It's fine if you want to give advice here and there, but it's rude to assume that everyone else is ignorant.
