Topic: [Off-topic] Bitmain will be releasing S15 and T15 on 8/11/2018 (Read 194 times)

quote the part where i complained about bitmain ? mining WAS not like any other business, I roied on some Asics in under 2 months, what other business can do that? not even drug dealers can do that ! .

plus you ignored the real question which is how do you calculate profit for mining? i answered for you but you are just refusing to admit it. ok so let us keep this plain simple, you told us your power rate  5.5 cents. and we will be able to tell exactly how much will it cost you to buy the S15. and we will assume those miners you getting are A+ quality that will last 10 years . why don't you prove everyone  wrong and come back when you get your ROI ?

i am betting "whatever amount you willing to bet" that you will never make it. bitmain is feeding of noobs like you and that's pretty much the only thing that keeps them going , noobs who pay close to 200$ for shipping plus 25% tarrif fees and with high power rate try to compete in the mining market.

so prove me wrong and come back when you ROI. other than this whatever you say is just B.S like everything else you said.

Oh hey cool, so you do less than me then. I did all my own wiring including breaker pulls and meters and panel installs and the friggin' feed lines from the pole, and configured the entire router/VPN and VLAN setups myself (after building the router hardware and rebuilding the VLAN switch), and built the shelves and all the exhaust systems from scratch, and I also design miners around bare chips and build them in my own factory. Where my prostitutemother works, on her back operating pick-and-place machines which will soon be replaced by better ones I'm designing and building around custom motion controllers and also writing the management software for.

But whoopty-effin-doo. Thank goodness Junior Member here has come to tell us what we're all doing wrong and insult us to our faces while insisting that we're the immature ones, and idiots to boot. Apparently you don't need multiple science and engineering degrees coupled with diverse skill sets and work ethic plus five years of reputable service to the community to get any kind of credibility around here. You just have to be louder.

Full of hot air! Like Bitmain's miners! See, totally on topic.

Sounds like we got a little snowflake here that is all butthurt because the meanie Bitmain took his Kleenex money. Mining is like any "business". You operate at the lowest cost you can and create scale at thin margins. I am a full time "miner". I do my own build outs. All set up and infrastructure. I wire my own electric and only use 3rd party hires for complicated network issues and pulling power to my Breaker boxes. Everything else I do myself. It's called "bootstrapping". You insolent little twit. I do this for a living. You just blabber on and whimper about it on the internet. We are all sick of you crybabies crying us a river about the evil Bitmain stealing your Lollipop. Grow up. You're all pathetic.

first thing first you should invest some time in learning how to quote your b.s instead of calling people names, or bring their mothers into an asic miner discussion.

yes i pay LESS than 2 cents per kwh and I am not going to buy those S15s, how is that your problem ?

then you talk about " profitability" , you must be a newbie in this field, you take the hashrate of your miner, paste it on whattomine and then say waw this is the greatest investment i will ever make, ROI in 6 months !! and 200$ monthly ! i am going to ALL IN.

you realize 3-4 months ago, antminer A3 used to net 8-9$  daily and now it is a door stopper ? antminer S9 did well above 8$ a few months ago and now it hardly makes 2$.

so how the fudge do you go about calculating "profitability" in mining business ? just because I have very cheap power rate does not mean i should invest in Asics when i already have bunch of them. most of which have got ROI "thanks to my cheap electricity" but i do not put all eggs in one basket.  mining is no longer an easy business that a newbie like yourself would invest 10k and get 50k same month next year. things have changed , you now have to treat mining as a real business, things are only getting more difficult for the average folks. 2017 is gone and it's never coming back. you need to wake up and smell the coffee.


Dude some people will never learn, come back in 4-5 months when you see everyone complaining about their S15 missing hashboards , and how bitmain dropped the price over 70% , and how difficulty is increasing regardless of btc price. the same people cursing bitmain for selling L3 for 50 bucks when they they paid 2500$ for it and never ROIed will be doing the same thing about bitmain S15. you just gotta wait and see .

I've never tested below 98th percentile, so "idiot" is not likely accurate. Profit's not the main goal in my business, never has been, and my preferred form of altruism is more biblical than self-formulated. But my business is doing well enough that I've been able to help everyone who's asked for it and a few friends who didn't, while also building (not using, not brokering, but creating with my own hands and employing people in my community to assemble) devices to help small miners compete and helping keep general awareness and interest alive among non-industrial consumers (which probably helps with general adoption, which is essential for your profits, right?).
Not sure why you brought my mother into this, but between farming, teaching high school English and over a decade managing a medical NPO she's quite comfortable dealing with jackasses and can hold her own in a debate so I'm not too worried.
Honestly, America's culture of using profit as the only metric for success is the main reason we cause global market crashes every couple decades, the main reason we lead the developed world in both starving kids and obese kids, the main reason our education system is a shambles and why we're trashing the environment hand-over-fist...


Chips that are capable of 42J/TH doesn't mean a miner is capable of anywhere near that. The S5's BM1384 had a bottom clock efficiency of 0.24J/GH but the S5 ran 0.5J/GH at best. S7's BM1385 had a bottom-clock efficiency of 0.18 but the later versions were 0.3 at the wall.
All ASICs run at lower efficiency when hot, and I've noticed the smaller nodes are even worse about it. So though a chip might do 42J/TH cold, at running temp it could easily be over 50 especially if running temp is upwards of 90C at the die. (for reference, I've seen a hot BM1387 stick run 170% cold power draw) Couple that with losing 5-8% of your juice in the board-level main regulator and you're seeing maybe 53J/TH board-level. If you're running 10W to the controller and another 60W to fans, up against 1000W of boards, that takes the machine-level average up to over 56J/TH. Then you're losing another 7-10% in the mains supply, leaving you with a wall-draw efficiency about 62J/TH (and a 1200W miner).

And that's assuming we're operating at bottom clock efficiency. The curves for these tiny nodes are a lot flatter than what we saw for 28nm and up, but not perfect. Assuming 42J/TH is bottom clock but stock setting is more like 48J/TH, and that's the hot efficiency, we'd still be looking at a wall efficiency of 60J/TH. Better but not revolutionary.

why do you chose to insult him that way?

I agree that comparing a whore to a janitor may not be a good decision.

But saying his mother is a whore is a terrible thing for you to say.

This is without a doubt the most myopic, ignorant thing I've read in these forums. If you're making "business decisions" based on something other than profitability you're nothing more than an idiot. If you want to use some self formulated definition of "altruism" to govern WHAT TYPE of business you engage in fine. I have no idea why you brought your mother into this.

Some people use metrics other than profitability to make business decisions. Doesn't always make 'em foolish. Is it better to make minimum wage as a janitor or a million bucks as a whore?

On the subject, I'd be surprised if Bitmain released a miner at 1200W. They haven't put out a BTC miner with expected power draw that low in about four years. Maybe they're finally realizing the density levels are unsustainable.

Well if you pay .02 per kwh and no tax but "won't buy those ASIC",  then you're a fool. But go ahead and make your ideological statement. Brilliant.

you do release the world is much bigger than the U.S right? i pay less than 2 cents per kwh , and 0 tax on asics.  so my profit and ROI are pretty much different from yours , nobody pays 24% for miners except in the states " non that i am aware of". huge farms in china ship their miners in trucks  " next door to bitmain warehouse" it costs them NOTHING to ship and pay no tarrif + they get good discounts on bulk orders !! and they get cheaper power rate than yours.

and ya people still run S7 but can you with 5.5 cents ? not likely !

what i am trying to tell you is (every one has his own inputs of doing the math), it may work for some while not work for others !

I will not buy any of those asics nor any other asics even with the dirt cheap kwh i have. but it's a matter of couple weeks till you see thousands of them being shipped across the globe mostly to noobs that  will never ROI

i do think he may be off in hashrate aspect, but as for power cons i think you are off, i am guessing 1400 or less , you know bitmain needs to target people who have only 100-140 volts too. and i do not think bitmain has any sort of psu that can supply anything above 1500w for those people. and ofcourse they would want to sell their psus as well !.

but still we are all just speculating here, the real numbers will be there in 2 days.

Funny that's what they said about the S7. People STILL mine with them. If your source is right, add in the 24% tarriff and the shipping cost and your S15 costs $1500.00 to your door. At .055 per kwh it make $7.81 a day or takes 6.5 months to pay itself off. I'm no math whiz but for $1500 I can get around 7-8 S9i's these days that make $1.64 at that rate. My guess is that the S9's on ASICBoost will do just fine as long as your power rate is decent.

I think he is off. If the Watt draw was that low, why did Bitmain release a 1800 watt PSU? My guess is 32 Th/s pulling 1600 watts ATW.
