yeah i also think, it's better to begin to accumulate from 400 as a reward not now, because right now there will be more dumping

from +400 to -100(from 500 top) is the best time frame to accumulate, the price will hold there and begin to rise again under 400(from what will be before we touch it)

Trying to catch that very bottom is like playing roulette. It is friday so more examples of that, there is more where this comes from.

There is no point in holding when block reward will double in the coming weeks. That means at the end of the climb, block reward will be 500 coins per block for a very long time. Coin emission per day is still increasing. Perhaps there is a point to holding closer to when it's maxing out (say around 450 coins per block), but not right now.

But when their software is released. and not in the BETA phase anymore, the coin could skyrocket. (77 000 pre subscribers and 2000 beta testers). This is going to be bigger than Steem.

Accumulate for 3 months from miners, and sell with a huge profit in the rally that will come..

Could... a lot of coins could skyrocket... a lot don't as well, but now we're speculating.

That aside, the coin would have to double in value to make holding now worth it and even then, the price will more then likely continue it's downhill decrease for quite some time.

There is something called opportunity cost. It's the price of hanging onto money or spending money a certain way when you could invest it in other avenues. Say holding onto your coins for the next three months, what could you do with that money in the interim? On top of it, plenty of people also have bills to pay which accrue, including loans and electricity cost.

For instance, even though the 1070 series was great at Lbry, for a little over a month, a 480 has been great at Ethereum and was pretty decent at Lbry on top of it (especially if you purchased Wolfs miner). Now that the Lbry boost is over, I own $450 GPUs that earn as much as a $200 GPU that weren't even that bad even during the huge Lbry burst.

You can make arguments for efficiency and such, but 480s aren't that bad efficiency wise (compared to the older R9 series) and it'll take a looooong time for that to pay off... Considering the rate at which all coins are declining, that may happen sooner rather then later though as we start to approaching 50% electricity cost vs revenue.

Sadly, a lot of the markets that are currently getting pumped are all ASIC coins. Mainly Scrypt... Cryptonote would be neat, but once again you would have to get close to doubling the hashrate.

I buy private Nvidia miners. Send information and/or inquiries to my PM box.

That is why I sold most of my gpu's already. Small boy in me wanted to buy new toys but based om my own calculations it just was not worth it, 500€ in cryptoland was better spend elsewhere than in 1070.

Best thing that can happen with my rigs is that fan fails, I get a new one which is at least as good as old one. Easy to sell for a good price if not opened.

I kept some because it is a fun hobby and you still earn something.

i agree but i´m not dissatisfied with my 1070s. They were a direct replacement for my old 7950s. In fact i put 4x1070 replacing 3x7950, on the same rig with an 850w PSU.

I still prefer these $429 1070s against the +$300 overpriced 480s, which were always out of stock.

Opportunity cost is certainly something to always keep in mind. But the same should be said of holding/dumping GPUs (in addition to ALTs). The investment any miner is making on GPUs, could instead be made directly into any number of ALTs, BTC, whatever, off the markets instead of mining.

In a sense, most miners are speculators, in that they are weighing the hardware investment/aging cost against unknown future returns. Not always the case though, as lots of people simply mine for fun (casually neglecting minor earnings or losses).

To me, mining is mostly a form of supporting the altcoins that I believe to have a future (by adding to their nethash and slowly increasing my stake/position), mixed with the speculative opportunity of mining smaller coins, ones which I would avoid buying directly off the market as the price moves too much on little volume. Well, that and insta-mining ninja launches! Just haven't seen an interesting one of those in a while...

same as you because the 480 was doing 160MH or something in lbry so yes they were bad, because you would have lost a huge amount of coin when lbry was at its peak, surely that huge amount would pay for the difference between the two gpu even now that they earn the same

not to mention that another lbry will come one day, i'm also mining for the future, and i want to mention that the 1070 on ethereum is better than a 480 in efficiency so still not the same even on ethereum

$450 is overpriced... They're supposed to be $380 MSRP. You can find 480s for $200, they're just rare and you have to hunt, much like the first couple weeks for 1070s.

Look up Wolfs private miner, it's in the Lbry thread and his hashrates.


Not saying that 1070s will always be bad, just right now 480s are definitely winning out as a better purchase for mining.

LBRY will go back up. Just hold it for some weeks instead of dumping it.
Yes that's what it looks like sp... someone bought 50 BTC worth. Now up to 100 BTC  Wink
If people hold or sell at a higher price...

Somebody has been buying for 100BTC every day for the last month or so.

At the peak LBRY MCAP was bigger than Etherum @ 1.2 Billion USD. (www.coinmarketcap.com has the wrong number of coins)

There are 404 455 928 LBRY coins

(https://explorer.lbry.io)


That marketcap is utterly useless if you look at the coin distribution:

https://explorer.lbry.io/richlist

Normally, I'd also plan on accumulating LBRY in the near future but we're only playing with dust here while about 98% of coins are tied.

That shit is way too centralized to me to find it even remotely interesting.

Not your keys, not your coins!

Wrong thread to post about this?
I've pinged Epsylon3 anyhow, he should check it shortly...

Edit: Folks still mining LBRY, would you care to post your efficiency ratings for whatever GPUs you have? I've tweaked for a bit, and wondering if I should waste any more time chasing improvements. My stats: GTX 1080 @ ~340MH/s & 150W, so roughly 2.27 MH/W. I wonder also how the AMDs compare, but that's really just curiosity, I have none of those.

The power usage is as reported by the Nvidia driver. I'm wired up with a reasonably good UPS, which is actually reporting lower power numbers (after accounting for the rest of the PC components), and it includes any PSU efficiency losses, so, go figure... I know I have a wall monitor somewhere around here, so when I find the bugger, I'll have that as well to better confirm the effective power usage.

Happy Mining!

Happy Mining!

MY EVGA CLASSIFIED 980TI GETS 220-250MH/s--

I don't have a wattage reading, never bothered to check.  Likely more than your 1080.  My EVGA 750ti cards get 50MH/s each.  No wattage reading again, though.

Right now I am going to re-arrange cards and power supplies. The plan is to populate the 750ti rig with RX 460 cards, and reload Linux from scratch on a 32GB SSD.  The 750 ti cards will move onto a uATX MB and a 128GB SSD in a 4 card rig.  The rig will have Win 7 x64 and dual boot Lubuntu 16.04 with CUDA 8.0.  That way I will be able to auto switch in Win 7, or compile the latest CCminer in Lubuntu.  The RX 460 cards can mine Ethereum (ETH) at 10-12MH/s each, as fast as a GTX 960.  My 960 cards are destined to move to a 4-card rig as soon as it is affordable.  Energy-wise, the RX 460 cards are between a GTX 750ti and a GTX 960.  EVGA Precision-X 16, their overclock utility, works with a maximum of 4 cards.  SO, 4-card GTX rigs; smaller motherboard, smaller power supply (PSU), better stability and control.  A 600 wat PSU is more than enough for 4 750ti cards.

I still have that "cpu bug" with lbry, never a found reason for that. Tdp limited 8-pin 970 does 13% more when running cpuminer at the same time with ccminer.

150-153MH/ gpu, cannot test power usage because it takes almost half an hour to get everything synced and running. 160-170 watts maybe?

That's a weird one and counterintuitive, but I think I'd call it a feature rather than a bug. Wink
I would expect the extra load on the CPU would cause scheduling delays for other processes like ccminer, although
it wouldn't affect the GPU hashing at all.

The only thing that comes to mind, very speculatively, is thread affinity. With some CPU cores fully loaded CPU mining
the ccminer threads are more likely to always run on the same cores possibly improving cache performance.

1070 G1 with only +50 Mhz OC at 100% Power limit: 270Mhs/178W so 1.48 Mh/W
90% PL: 263/162W so 1.62
80% PL: 252Mhs/142W so 1.77
70% PL: 243Mhs/125W so 1.94
60% PL: 226Mhs/107W so 2.11
50% PL: 202Mhs/91W so 2.21

Take the numbers with a grain of salt as I didn't wait much between readings and the power consumption figures are from nvidia-smi.

Anyway, if you do the math higher hashrate trumps efficiency as it almost asways do (if you have average electricity prices). In fact, I've yet to run into a situation where lowering the power limit would have lead to more profit...

With $0.14 kWh LBRY would have to be priced as low as roughly 7k sats for higher efficiency to matter more than hashrate - at which point people would not mine it.

I still have that "cpu bug" with lbry, never a found reason for that. Tdp limited 8-pin 970 does 13% more when running cpuminer at the same time with ccminer.


That's a weird one and counterintuitive, but I think I'd call it a feature rather than a bug. Wink
I would expect the extra load on the CPU would cause scheduling delays for other processes like ccminer, although
it wouldn't affect the GPU hashing at all.

The only thing that comes to mind, very speculatively, is thread affinity. With some CPU cores fully loaded CPU mining
the ccminer threads are more likely to always run on the same cores possibly improving cache performance.

That rig has i5 4690k@default.

I am not sure about this yet but it might find blocks more often than it should againts rigs with more hash+weaker cpu.

1070 G1 with only +50 Mhz OC at 100% Power limit: 270Mhs/178W so 1.48 Mh/W
90% PL: 263/162W so 1.62
80% PL: 252Mhs/142W so 1.77
70% PL: 243Mhs/125W so 1.94
60% PL: 226Mhs/107W so 2.11
50% PL: 202Mhs/91W so 2.21

Nice. Thank you for the details there @bathrobehero.

I'm a bit more focused on efficiency than raw hashrate, as my electricity cost is at €0.20 kWh, as well as many times I am mining at loss (or rather, not strictly mining for a BTC output, or mining for low key hoarding).

But the other thing I would highlight, especially with the larger cards (1070/80, 970/80), is that sometimes, and only to moderate extent, you might lower your power usage without any loss of hashrate. This is a function of operating temperature, clock & voltage controls.

The default clocks for my cards (factory OC'ed), achieve roughly ~340 MH/s @ 180W, with the cards running in the range of 70°C.
I can't overclock them much at this range, without hitting temperature and/or TDP throttling. A little increase is possible, but marginal, and with a good deal of power usage increase.

My tweaked settings run at the factory OC, then +140 clock, -1000 memclock, and 85% TDP, which comes out a temperature of 65°C (fan settings unchanged).
The hashrate stands exactly the same as the factory settings, yet my power usage is down by at least 15%.

Obviously results will vary across different cards, vendors, power circuits, ASIC quality, etc. But the gist of it is, that most times, for any given absolute max hashrate at default settings, you can usually get away with better settings to produce the same hashrate at lesser power usage.
I haven't ventured in similar testing for memory intensive algorithms though, I only ever tweaked to any meaningful extent on compute heavy algorithms.

In your case, the 1070 G1 with +50 Mhz OC at 100% Power limit. Would probably be perfectly stable with a tighter power limit, lowered memory clock, and higher core clock - again - producing the same hashrate, but with lesser power usage. It's not something that would interest everyone though... Things will quickly get messy as one changes from algo to algo, with the cards behaving quite differently from one to the other, and sometimes requiring significant reconfiguration.

Enough mining chatter, weekend here I go! Cheers  Grin

I agree. There's also seems there's a big difference in efficiency between the 1080's and some high factory OC 1070's.

My 1070's at +50Mhz are runing at ~1949 Mhz and I tried lowering PL and increasing the OC but then my rig crashes eventually and I have yet to find time finding the cause.

Anyway, have a great weekend!
