Interesting but I don't really see this being profitable, $888 for 6 Th/S isn't really all that good and for everyone with electric over .09 cents/KW this thing isn't profitable enough to even break even on the miner, then factor in rising difficulty and its really a total loss for most people. It's not like you can really resell this for much after, look at the S5 its selling for like $40 now.
Can't look at it per-miner. Gotta look at farm income. Give the age of miners I have running most are long ago paid off and making
BTC for upgrades. Even the latest s9 b18 I bought will paid for
by the entire farm in another 7 days.
Now, if starting from ground-zero with these, ja would be rough but I'd still take the risk.
For me running 18x s7's (and 9x s9's) it is a good upgrade value for the s7's I have running. Almost 2x the speed vs uv/c s7's at same power per-miner.
It's not overly difficult to start from the ground up. Purchased 1btc worth of s7-ln's used income from that to purchase another s7. Used income from that to purchase another s7...etc.
You just have to accept some of the expenditure as hobby cost and you reach ROI real quick.
Rarely will I keep all of my quoted bits when I reply but
THANK YOU! Usually this goes on deaf ears. Yes, ya gotta roll them bones and start somewhere.
#1 Rule: Even if going into this with ideas of a business, Consider your initial $$$ investment be it for 1 miner or 100 miners SPENT. Gone. Period. End of Story.
Do not EVER use money you cannot afford to lose or pay back! I hope it is needless to say, never take out a loan to buy miners... Look at it like planning a nice long weekend or vacation at you favorite casino. I for one have a good idea of how much $$$ we set aside for gambling losses for our time there. If we win enough to lets us play all day/night while we are there, Great. Fantastic. But still have the probable overall gambling losses vs money we brought in mind. We walk in the Casino considering that money spent.
After that, reinvest all possible
BTC income back into expanding the farm. Yes it takes time but over a few months it will get surprising how many miners you can get as it becomes more affordable from a farm income perspective

. My main limit has been total power I have available (for free at work) and care to pay for at home. Total is around 28-29kW.
Finally, something missing from all of the "ROI" calculators oft mention in the Forum: The plain and simple fact that since here in the USA the IRS wants a piece of ALL
BTC you convert to Fiat be it reported as Personal Income (and subject to Capital Gains Rules if earned from Trading) or reported as mining business + folks keep talking about ROI
then treat the cost of miner like the business expense it is! From a business perspective a miner is the same thing as an office PC and for Tax purposes is a business expense/writeoff. Last I recall the full amount can be written off in 3-years. Yes is a long time in Miner Years but - I have s7's still making money and some are from day-1 they were available so...
Since can't expand to use more power and limited miner availability restricts my s7 to s9 or A7 upgrades, um, BTC is starting to pile up again. Along with a growing pile of off-line s7's...
