Yes quite disappointing eh? I was hoping the difficult would get reduced by like 25% or so, so my 8GB would be more profitable however. The E3 and 4GB GPUs going offline has done absolutely nothing .

I guess globally there must really be millions of GPUs out there mining or some high tech ETH ASICS that the E3 shutdown doesn’t make a blip in the hash rate charts.

Might still go down when epoch 382 hit in 2 days. However I doubt it will even cause hashrate to decrease by 5%. I guess bitmain had a supply constraint of the DDR2 ram chips and couldn’t mass produce the E3 miners.

Can someone post their config for miningpoolhub? I can’t get it to start mining under that pool. It connects but doesn’t do anything after. No error or anything so no idea if it’s the wrong pool, port or username, wallet.

I used ethermine before and it uses an ETH address but MPH uses usernames instead and I think this is what is causing these issues. I tried using

—user
—username
—wallet

If someone can post their working config file I would appreciate it. I used the same configs displayed on MPH for like Z classic but with my own host and port and still didn’t work.

My 4GB GPUs stopped mining on epoch 381 which started 2 days ago. However there are reports of some GPUs going until epoch 382. I think it’s the same with the E3. Some are still hashing while others are down. I think the final nail on the coffin will be in 3 days when epoch 382 starts. No more 4GB GPUs (unless they run that lolminer software) and E3 will cease to mine.

Will hash rate decrease? Honestly I don’t think it will change much. When epoch 381 hit, the hash rate went sideways. And assuming same for epoch 382. I think many knew this was coming a long time ago and upgraded to be prepared.

I actually was hoping to see a hash rate reduction when 4GB went offline so the 8gb would be more profitable but doesn’t seem to be the case here. Newer ASICS are vert advanced and efficient and so are some of the GPUs that were released in the last year.

It’s because your 4GB are reaching the dag limit on ETH. Basically you have 2 more days on epoch 381 and when epoch 382 will start they will no longer be able to mine at all. There is another miner that if you search lets you mine for another month or two but I don’t want to mention in this thread since it’s not phoenixminer specific.

I would just however remove those 2 GPUs from the rig and sell them on Craigslist. Then add some money and buy an 8gb version and you will get your 30mhs speed back. Nothing else to do. You can mine etc at half the profit however I don’t think you want to do that.

No unless the difficulty is fixed however on many pools the difficulty varies with hash rate. Shares carry a different weight. If you send 1 share of 1000 difficulty it’s the same as 10 shares of 100 difficulty. Why do they do this?

It’s to prevent server laggy and reduce variance. Each pool wants to maintain a certain shares per minute and adjust the difficulty until it achieves that desired result. Hence why your shares per min are similar on your 2 rigs which hash at different speeds. If a faster miner sent too many shares it would just slow down the pool. And if it took forever for a slow miner to send a share there would be huge variance at the beginning.

No the mining isn’t real. There was some popular coin in the past, I think it was called like Einsteinium or something like that. Basically it was fake mining but you got paid rewards anyways. It was pretty popular actually. However in the real world, you just cannot make a coin that is purely based on proof of work using mobile devices.

Reason is security. A phone is very low power and doesn’t really have much computation compared to a high end intel or amd processor. Hence one high end processor can emulate maybe hundreds of phones. And someone can easily rent some AWS servers and do a 51% attack and the coin would be in trouble. Hence why it’s been over 10 years of Bitcoin and there hasn’t been a single POW algo based on mobile devices.

Another reason is safety. If you mined 100% on your phone, you would cause it to overheat and might damage something or heat up the battery and start a fire.

I was also wondering this and thanks for doing the grunt work. However can you calculate how much profit mining would of yield if a miner just mined everyday and sold at the market for US dollars. I think the reason why the other topics are getting heated is because there is a big difference between mining and holding and mining and selling.

Obviously it would be a different story if ETH was at $55 now rather than $550. So if ETH went to $55 it would of obviously been more profitable to mine and sell rather than hold which would of resulted in a huge loss.

I think that $19.9K or whatever the official price was might be the high of the year. The market is getting really choppy and many forget that with the holidays coming up there will be less activity. Most will spend time with family, especially with all the crazy things that happened this year.

The proof in this is news such as Microstrategy buying $500M, another insurance company buys $100M, tether prints, and price fails to rally. It really should be at ATH right now but its not. Also there is lots of deposits into exchanges from miners and large whales.

So I think top is in and best case we dip to $15K before ATH again or lower to like $12K before ATH again. Don't see us going below $10K. If we do get to $10K, will buy as much as I can.

Is it really greedy buying over $500M worth of Bitcoin on debt? Well it seems like it but if you think about it. What else is there to buy really?

Real Estate is a bubble in most places and lots of work to maintain and rent out.
Dollar is tanking every week with all the money printing
Gold doesn't seem to want to appreciate as much as stocks/bitcoin
Stocks are all overpriced with PE rates going forward 10 years.

Hence maybe he is buying bitcoin because there is really nothing left to buy.

Yes this is the post he is referring too. Basically for some reason my rigs stopped on Epoch #381, while for others it should work until #382, strange. It seems that the speeds are "ok" until Epoch #385 which hashes at 82% from full speed, which is around year end. Epoch #390 and on are just not worth it at hashing 50% speed. So I would say you can use it for 3 more weeks and then think about getting 8GB gpus because its going to be highly unprofitable by then.

Here is the post
https://bitcointalk.org/index.php?topic=5281830.msg55389967#msg55389967

Best time to mine is basically when its unprofitable.

1) You have less stress because if your rigs crash in the middle of the night, you don't really care about setting alerts on your phone and lose sleep. Would you let your rigs crash in the middle of the night during the days when each GPU made $10/day? Probably not. Mining is really stressful when its profitable.

2) Its very difficult buying GPUs when its profitable. You basically need to speed to the Craiglist sellers house to buy the GPU before they up the price or remove listing and mine themselves. Or you got a Limit 1 or Limit 2 quantity at the computer store with a 20% mark-up. This leads to longer ROIs

3) Difficulty is very low because alot of people shut down their gear and moved on. Hashrate now is 295TH/s while when ETH was $100 it was about half this value.

4) You don't need to worry about getting returns if your sell your gear on eBay. During a bull market, many buy their gear on eBay which is the worst time to get screwed. Sell a GPU, 3 months later you might get hit with a return because buyer wants money back because "mining profits are lower". Instead they say its because "Not as described".

Finally got my 4GB back in action again mining ETH. I assumed it would be troublesome and not worth the hassle but that lolminer program really works even with DAG >4GB. The speed I got before was like 29MH/s and now its 28.5MH/s. Power usage is slightly less probably due to the slower hashing speed.

Program seems stable and hasn't crashed yet. Pretty easy to set up, nothing to configure really just use the provided *.sh files and put in your own pool and address. Only thing is certain feature like ttli, or remote monitoring either aren't available or I can't get them to work.

Only issue is that this program will be good maybe for another month or 2 and then the speed will just be way too slow. I think by March or April it will hash at like 50% of the normal speed. But till then might as well use it. Hope the overall hashrate lowers even more with 4GB cards shutting down and E3 going offline.

I am using Ubuntu. And I don't set the core/clock/voltage with software. They are hard-coded into the bios. So the core engine clock, memory clock, and the voltage are all identical. But the system is for some reason using too much wattage and one of the GPUs quickly crashes after 5 mins or so.

The speed is almost the same as PhoenixMiner, maybe 0.50MH/s or so slower per GPU but overall the speed is good enough but is there a way to throttle the GPUs so they don't overheat, or at least a way to lower the intensity? Also how do you disable some GPUs in the terminal? Is it possible what about in the config file?

Decided to try out this miner since DAG #381 no longer worked with phoenixMiner. Was pretty easy to set up however I am wondering if it has some features such as Claymore and Phoenix.

One featured I liked was the -ttli, where it throttles a GPU if it goes over a certain temperature. If it doesn't have this is there a way to reduce the intensity of a GPU?

Another question is why it uses more power than Phoenix/Claymore using the same voltage and clocks? My rig used 700 Watts and now it uses 800 Watts.

Well woke up today and my 4GB old rig was down. Decided to reboot it, and it fails when loading the DAG. Apparently #381 is the last dag that works for 4GB under Linux/Ubuntu. So I guess this was the end of the road for the 4GB cards. Bought them in Summer 2016 so they lasted many many years. Only issue I had was dead fans.

Maybe or maybe not I will try that lolminer however I don't think its worth the hassle anymore. Unless the hashrate is reduced alot and the slower speed is caught up with the lower difficulty. Will keep checking https://etherscan.io/chart/hashrate and see how the next couple of days will go.

If you check a pool hashrate, https://ethermine.org/statistics  it looks like there was a dip but it quickly went up again, only loss was 1TH/s of hashrate.

It seems this is like 2017 again where people are buying crypto on their credit cards, lines of credit or mortgaging their house to buy BTC. Except this time its the institutions that are doing this. Isn't this similar to what MicroStrategy is trying to do. They want debt to buy more bitcoins, over $550M worth. I guess this is mostly due to the fact that the interest rates are low, inflation is high and everybody is dumping the dollar.

So its all fine and dandy until there is a massive correction. However I am pretty sure most instituions with debt can easily wait it out unlike the 2017 crypto investors who had 20% APR credit cards due and also huge capital gain taxes to pay. So I would say its overall bullish. Lots of bullish news this week but BTC still fails to break ATH. Not the signals I was hoping for.

I think there are buyers but the buyers are high leveraged traders using derivatives and they got tight stop losses or they are over-leveraged and a 2-5% move can liquidate their entire account. This is observed because usually when this happens there is a massive price decline followed by a huge volume spike and usually right after it resumes its original intended move.

There can be also spot buyers who are nervous and want to buy either at $19K or $18K but they don't want BTC to go back down to $10K so they buy and use a stop loss. So the people that bought at $19K probably got stopped at $18K and so forth. However the institutions are buying up all these bitcoins which are sold under panic.

Anyone know if GPG is included in the Live CD of the Ubuntu OS? Was going to switch over to a keystore however did some searching for linux based encryption software and GPG is included as a standalone app in certain Ubuntu releases?

From what I can tell all you do is type "gpg -c SEED.txt" and enter a strong password. To decrypt just type "gpg SEED.txt.gpg" and should ask for password before it decrypt. Wondering if anyone had any issues using gpg in the past to encrypt their documents and seeds. Are failure points I can run into? Is there an encryption option I can select such as 128bit vs. 256bit? or is it just some standard ?

I've owned the Radeon 6990 before. Its basically a monster of a GPU. Its dual GPU and I think that beast can pull 600 Watts or so. The guy I bought it from mined actual BTC with that GPU and I've mined LTC, X11, ETH, ZEC, and XMR. That GPU basically refuses to die. Runs pretty much at 90C day and night. Blower fan running at 80% for maybe half a decade and still has good fan bearings.

That GPU and Radeon 7990, are actually limited production GPUs. They are rare and hold decent value. If yours is in mint shape you should hold it for another year or so and some collector will buy it on eBay. Currently the 7990 is going for $200 or so. Which makes no sense since its basically 2 of the Radeon 7970 (R9 280X) gpus which an overclocked RX 480 can pretty much beat.

The rest of those GPUs however are nothing special and you won't get much coin out of them.

There are miners out there that basically mine and as soon as they get a pool payout sent to their exchange wallet, they market sell whatever that figure is. I don't know how accurate this is,
https://bitinfocharts.com/comparison/ethereum-mining_profitability.html

But it shows you the profitability per USD/day for every 1MH/s of hash. Now if you use Jan 2018 as a start point and yesterday as an end point, you can see that the average for the past 2 years is like 0.027 USD/day per 1MH/s. So an RX 480 which hashes at 30MH/s made an average of $0.81 per day for the last 2 year, if power is $0.10 or so, thats a net profit of $0.50/day.

There were many weeks or months where if you had to pay for power, you were pretty much making almost nothing. So after 2 years at $0.50/day is around $365 per RX 480. If they retailed for $200, you net $165 and now you can resell them for $80 so a net profit of $245.

The real money was made however in hodl'ng those ETHs and selling at the peak last week at $600 however.
