141  Bitcoin / Mining speculation / Re: Did difficulty just go up again? on: December 19, 2017, 07:20:48 PM
The blocks are solved on average every 10 minutes, if they happen quicker than that difficulty goes up, if it happens slower then difficulty drops.

So, you can see how adding more and more hash speed to the network makes the difficulty go up.

Ok Ya I can see that now. So if the price of BTC plummeted and miners started pulling the plug because profitability was no longer there then the difficulty level would drop compensating for the reduced amount of Hashing.

Yes, BTC would have to drop to under 2000$ though. Not impossible, but it seem improbable to me, now.

Could you explain why you're posting this on the market board? I do not see the importance of this post, but if you feel it is relevant, maybe post it in Meta board, which is discussion about event on and about this forum itself.
143  Bitcoin / Mining speculation / Re: What are the odds of actually getting an S9 from Bitmain when they are released? on: December 19, 2017, 03:59:39 AM
Ill keep saving and watching. Ive never ordered from bitmain before so I didnt know if it was going to be one of those good luck getting one sorta things.

Yeah its one of those good luck getting one, also good look getting it on time and finally good luck and not get any sort of defects.
144  Bitcoin / Mining speculation / Re: Did difficulty just go up again? on: December 19, 2017, 03:44:44 AM
I did. Thanks. I didnt know if anyone would have anymore input other than it goes up every two weeks.

It goes up every 2016 blocks, so 2 weeks more or less, more often less because hashrate go up. If you'd like more input, ask more questions.
145  Bitcoin / Mining speculation / Re: Is it worth buying a 180-200GH miner? on: December 19, 2017, 03:19:16 AM
I'm considering buying the Antminer S1 used on ebay for 99-120$. The S1 has 180-200GH and I think that this would be a good entry level miner. I do not pay for electricity so power consumption and efficiency are not factors in my decision to buy this miner. My only concern is that 180-200GH's is not powerful enough to actually output a significant profit. The mining caculators suggest that I should receive about 150-180$ per year but could this miner being slow prove some problems for me. Thanks!
-Todd

Also that is a crap miner sold at a ridiculous price. I can't imagine it being worth more than its weight in scrap. You should be able to buy a S3 for that price. But no its not a problem per se, except reaching minimum payout from pools. Or a minuscule chance of finding a block solo.
146  Bitcoin / Mining support / Re: Do ASCI miners consume a lot of bandwidth? on: December 19, 2017, 03:17:14 AM
Hi, In australia the internet is quite rubbish. Just curious the bandwidth input/output say  an s9 would consume?

It depends a bit on how much data the pool is making you upload, and other minor factor, but a hundred devices would probably still be in low mid 2 digits kbps. If that become a problem, you can use a local proxy, but it's in most case, not a problem. The bottleneck is usually active connections handled by consumer grade routers. For example i have one device atm using an average of 0.4kbps with U/D combined.

If you have money for a massive farm, you can probably afford a 70$ router using custom firmware or a used industrial grade one.
147  Bitcoin / Mining speculation / Re: Network difficulty up, mining profits down by 15% in 24h – Will it recover? on: December 19, 2017, 03:09:49 AM
Hey there Fanatic26,

Thanks for your honest feedback, you are right, we should be prepared for the worst case scenario.

Not knowing the formula behind these calculators though makes it more difficult. Do you or does anyone have a clue of what formula does Antpool/Cryptocompare use?

And in the current uncertainty context, would you, as per your experience, consider it a wise choice to make such a bet by paying now for miners that will be delivered in April?

In these circumstances, I think it may be best to just switch to a different cryptocurrency, unless we're forecasting a massive raise of BTC value which may compensate for the insane increased difficulty (we should be forecasting a similar growth trend in the long term).

Cheers

I already told you the formula, if it doesnt make sense you may want to do some more textbook research on the terms used, until what we told you click;

You can't know what the difficulty will be, but you can expect it will go up.
No it will never, and never(until the BTC mining phase is over anyways but you dont have to worry about that for 100 years or so) will "go back down to go back to X" and normalize or whatever. To go back that much, like you asked, about 33% of the network would have to be taken down. Why in the world would you hope or expect 33% of all machines to be turned off by people profiting from them?

You asking this repeatedly seem to show that you do not understand what I and others have told you so far. Pay attention;

In general the difficulty will keep going up as long as its profitable to do so. More profit, more people get in, everyone get less BTC because everyone share the same pie. Simple, logical, make sense right?

Why does everyone make less? The BTC reward is fixed per block until halving every 4 years ish. More people mining = more people sharing the same reward limit.

So if the network double in hashrate, the reward is effectively halved, because it will take twice as much time to find a block. It's simple mechanics to grasp, easy to build a model on. But the prediction of actual values is hard to grasp and impossible to foresee with accuracy, just assume 10% growth average constant, forever, if you want an idea.

Again. Is it very profitable? Yes = Everybody and their grandma, just like you, want said profit, they jump in on the wagon. Consequence, more people share the same reward = less BTC for everyone.

Regardless, be careful because your approach seem to forget the most important factor; actual value of BTC (fiat/purchase power). It is more important than difficulty. I shouldnt have to explain that one. Smiley

148  Bitcoin / Mining speculation / Re: Network difficulty up, mining profits down by 15% in 24h on: December 18, 2017, 10:21:45 PM
*cropped*
I'll be glad to update you once we go ahead with the process, but what machine we use is irrelevant to the question I outlined in my post.

- So, about the network difficulty, I understand it's a gradual thing, but 15% in 24h, does this mean in one week it won't be profitable anymore?

To give you an idea of the situation in USD, yesterday my forecasted monthly profit with 800TH/s was 71.5k$, today it's 60.7k$. And that's considering Bitcoin at 19.15k$ (it has actually gone down 1k$).

If network difficulty keeps going up at this rate or BTC goes slightly down, I won't even be able to recover the investment in months.

Cheers

Indeed, its not relevant, but what i said refer to very low chance of seeing any of the hardware at the expected date, hence vapor, for now. Moving on, difficulty jump;

It happens every 2016 blocks, target 1 block per ten minutes average and is based on effective network hashrate, 15% per day is inaccurate and impossible it would mean the whole world's mining operation tripled in 8 days.

So for explanation sake, if the whole world was using only and exactly 100 000 Antminer S9, and you online 10 000 more immediately after new diff change, and they remained at 110 000 S9's you would have a 10% ish difficulty increase over a bit under 2 weeks. Now scale that up to current massiveness of the whole network and that's how it works, but with many more actors.

So if you want to guesstimate growth, look at the past and forcast future deployments as best as you can.
149  Economy / Service Discussion / Re: Do you trust the Chinese shippers on AliBaba? on: December 18, 2017, 09:33:57 PM
You're covered pretty much like ebay, just make sure to contest if the seller is trying to weasel you in any way before the timer expires. From China a lot of packages are late, simply ask to extend until you receive the package and contest if they try to weasel you.

I believe that they only get the money when you confirm good received or the timer expires.
150  Alternate cryptocurrencies / Mining (Altcoins) / Re: Is gaming motherboard ROG STRIX Z370-H GAMING ok for 6 x GPU mining? on: December 18, 2017, 09:28:22 PM
Hey, I've got this motherboard and was wondering if it's fine for 6 x 1070ti GPU mining rig? There's only 3 slots that I can use with risers to bring GPUs up like everybody does and then 3 cards should be put on the motherboard? Just wondering if it's fine or I should buy motherboard like everybody else uses.

https://www.asus.com/Motherboards/ROG-STRIX-Z370-H-GAMING/

It's got:
2 x PCIe 3.0 x 16 SafeSlots (Support x16, x8/x8)
1 x PCIe 3.0 x 16(at x2 mode)
3 x PCIe 3.0 x 1

Probably, but i'd go for cheaper/mining boards, like the TB85 for like 60$ on LGA 1150. They're a strait upgrade from H81 etc pro btc boards.

You shouldnt plug gpus directly into the motherboard, go 100% usb risers.

Beside your mining hardware speculation on currently vaporware your difficulty estimation fairly reflect how it is. Yes diff go up, reward go down, thats how it is.
152  Bitcoin / Mining speculation / Re: Japanese company GMO announcing new hardware and mining operation on: December 18, 2017, 06:32:06 AM
I'd love to see some fine Japanese engineered ASICs, their standards are much higher. I'll wait and see, with a healthy dose of skepticism and refrain from any hype.


How to buy chips or boards from GMO?

Does anyone have contacts with the company that produces the chips within the GMO consortium?

Did you even read the long post you unnecessarily quoted in full? Tongue Its a company announcing (or optimistically stipulating) that they will/want to make this, next year. Tongue
153  Economy / Service Discussion / Re: Is Bitcoinware.shop a scam? on: December 18, 2017, 06:17:14 AM
Just found https://bitcoinware.shop/ and they have great pricing on the Antminer S9, but something just seems off with these guys.

It's almost a carbon copy of another site called bitcoinware.net

Is it a scam?

Yeah looks quite scam. 3 months old domain, hidden origin, but listed as Canadian website. Its mirroring stuff from bitcoinware.net, which is not a scam, but the guy running it... doesn't provide a good service. Considering the 50-100% minimum markup on the listed products, you'd think he'd hire staff if he find his job is too hard to do. Please ignore the following;

rant;
I've had multiple problems with him, last one is buying ASICs and not getting any sort of reply or feedbacks when asking why the devices due for 6 weeks before hadnt even been shipped, or he didnt have 2 minutes to update his website to let people know the batch was delayed due for whenever x new date. You can check his website now he still has pre order for November batches.............. >.>

In the end i told him i did a charge back and hoped he would have enough complaint registered to open a fraud investigation and lo and behold near immediate response and full refund. Sorry dude if you're reading this, but as a customer, your service is worse than cheap Chinese websites. When you're worse than Bitmain, it ought to send you a wake up call or something. Anyways.

154  Economy / Service Discussion / Re: Any newer reliable distributors/online shops for ASICs for Canada? on: December 17, 2017, 06:26:16 AM
ASIC market is insane right now. S9s on eB going for triple retail and up. A few resellers on Amz same thing. Bitmain is selling out months before they're built,  people w/$$ buying lots, 10, 50, @1600, resell @ 4-5k ea. If you see one for 1600 be very VERY suspicious,  unless you too have enough $$ to bulk buy direct and it's the manufacturers site. I Expect the logjam to break in February/March but even if I'm right it's soooooo far away. Cheapest s9 I've seen last 30 days was 3800 USD. Good luck and be careful,  scammer count goes up with bitcoin price.

I heard you ^_^"

I have never (successfully) been scammed here, you can see scammers coming miles away, in hordes, and even if they dont look it, escrow is gold.

We'll see for prices, i also saw bid wars on S9 PREORDER for Jan batch going to 5k USD. WTF.

I seem to see a few china suppliers that would sell to me, but i'm thinking of staying away from Bitmain ASICs. I would buy it from a shop that guarantee the service for the 3 months, because i've only had bad personal experiences with them in that regard, and the forum is overflowing with Bitmain Warranty horror stories.

Personally i may be more inclined to buy ASICs for other algos but that's a discussion for another board.
155  Economy / Service Discussion / Re: Any newer reliable distributors/online shops for ASICs for Canada? on: December 17, 2017, 03:49:12 AM
Yeah like I said, the A821 is coming.

It has not yet had an official announcement and release details.

Which mean i can't buy it.

157  Economy / Service Discussion / Any newer reliable distributors/online shops for ASICs for Canada? on: December 17, 2017, 12:09:04 AM
I ask because i haven't really been paying attention to ASICs sellers for a year an a half, i grown my farm enough to re-include ASICs and sourcing units seem difficult at the moment. Worse case scenario i will use alibaba..

But if you know any sellers in Canada or USA that sells/ships to Canada, i'd like to hear what you have to say, just don't say Bitcoinware.net. Smiley
158  Bitcoin / Mining support / Re: Setting up 2 antminer s7's in apartment on: December 15, 2017, 02:08:24 AM
NOPE. I'm well versed in the art of mining out of an apartment, S7 are loud as fuck. Imagine taping an air dryer to each ears. Other than that...

The best way to do it is to buy a good bang for buck 30A/40A PDU(60-100$ shipped), and change it's plug to fit the outlet you have, adapters and adding length, i would not recommend.
Rewiring is easy, if you insist on using an adapter, make sure its short and rated for more than you will use, more than the usual 80%. From the PDU, i had C19, so i plugged a strip bar that has a bunch of C13's.

Easy, just make a box and do a hot aisle cool aisle by having the ASIC push its own air directly outside. I did that with Falcons, Antminers S4 and S5 back then. I didn't even need to use a box fan to do exhaust.
