I want to be clear the extra feature are on the multi chip units
4 chip btc miner has 2 fan jacks and the ethernet jack
Those features are on the bc04 I tested and demoed
https://altairtech.io/product/hammer-miner-bc04-home-bitcoin-miner/I also owned and tested these both have 2 fan hook up with ethernet cables
and the dc04
https://mineshop.eu/hammer-miner-dc04-210mhsand the dc08
https://www.hammerminer.com/dc08.htmlI am working on getting the newer chip bm1373 models
but frankly for me the BC04 , DC04 , DC08 models are really nice gear.
I am getting the futurebit soon .
I will compare it with these and of course show the modded t21
A grand total of :
4 from hammer miner
1 from futurebit
1 diy 2 board t21 using parts from zeus (the fan) and altairtech (the controller)
all of the above on hand
and hoping for some bm1373 chip miners from hammer.
All of the above are what I define as hobby gear. which under USA law means that over a five year time period you lost money in all five years or in four of five year you lost.
to be a business under usa law you need to make a profit in at least 2 of 5 years.
my 10 big bitmain miners getting hosted at corx make a profit and are a business miner.
there is a place for hobby
there is a place for business
when it comes to mining.
For me right now in my home the modded t21 is too costly to continue to mine
my summer power is 28 cents a kwatt and I can not justify mine and spend that much power.
but mining the BC01 at 17 the BC04 at 70 the DC04 at 47 and the DC08 at 94
is only $1.51 a day in power in the summer
and $1.13 a day in power in the winter.
I keep the BTC miners on solo and just mine and stack the scrypt miner coins.
so I could hit a solo block and holy freaking shit I score
or ltc /doge could spike and I do okay
