6301  Alternate cryptocurrencies / Mining (Altcoins) / Re: Is it still profitable to run a mining pool? on: July 17, 2019, 09:28:15 PM
It doesn't take any electricity to run a mining pool. All you do when you run a pool is basically have the wallet open and you accept shares from your miners and when a block is found your split the reward based on the equal share count for every miner. This only uses some CPU power and not much else. It might be more dependant on larger SSD and RAM depending on what type of coin pool you want to run. From what I heard Ethereum will require more resources than some new alt-coin based on a Bitcoin clone.

It used to be profitable to run these back in the day but these days people just stick to the big pools. And usually won't switch to a newer pool due to trust issues and the fact that if there aren't enough miners it will take a long time to find a block.

I assume that you live somewhere in North America with 120V power.

There are a few ways you can get 240V. One way is to use the stove and dryer plug. Those are always 240V.

Another way is you can probably just join 2 seperate breaker outlets which are 120V. Now you should consult with an electrian first before you do this because I don't know if its going to be up to code and everything. So do this under your own risk.

But I believe the Stove and Dryer plugs which are 240V are basically 2 separate 120V joined together with a larger fuse. However the wiring is probably a different gauge so you will be stuck with a smaller 15A instead of the 40A which are used by Stoves/Dryer.  Again I am not an expert so ask an electrician first.

Im using M2G Android Miner to mine Monero. But you need a lot of cellphones to achieve pc-like results.
Eg my S6 gets about 15 h/s, but my S9 gets 40+ h/s.


Its pretty bad that an S9 can get 40H/s when an RX 470 gpu gets like 1000H/s. The RX 470 can be had for like $50 on eBay and an S9 is still a pretty expensive phone. It also has a battery inside that will most likely explode due to the sheer constant heat of the mining. And right now its not profitable to mine with the RX 470, so mining with an S9 is even worse.

If you really want some money and got some spare phones, just put them on Craigslist and sell them for cash and use that cash to buy crypto instead. Not really worth the headache and like the above poster have said, its a scam fad and the other phone miners are fake mining and you won't actually make any profit.
6304  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: July 17, 2019, 08:28:04 PM
The original poster of this thread back in 2015 should go back and change the topic of this title. Because we are getting the same questions asked over and over again and it creates alot of confusion when it says "Puzzle" in the topic while this in fact is not a puzzle.

A puzzle is something that you can solve with a pattern, kind of like solving some mystery.

However the way you solve these private keys is mostly by brute force and its no different than solving for any private key the only difference is that these are low entrophy.

So instead of this being a puzzle its more of a test of human coding skills and available CPU and GPU and FGPA hardware.

Honestly, who plays 0.25 btc hands on blackjack? That is literally 2.5-3 thousand dollars each hand, that is a huge whale move if I have seen one, normally in real life you sit on a blackjack table and you will realize the biggest is usually 50 bucks per bet, I rarely ever see a person betting anything more than that, keep in mind this is a regular casino blackjack table, not Las Vegas big 5 star hotel with insane entertainments type of table, which means this dude is betting so much that if he cashed it out to dollars, go to Vegas and bet on blackjack he would be treated like a huge whale even there as well among all other whales. If you are attracting that type of customers to just sit at home and gamble on a website than you know you must be doing something right.

If you think that this is a big amount, then you must be wrong because there is more than just 0.25 btc play on stake. It is a big amount for us but this is just some tiny pennies for big whale so it does not really looks big for them. You should checked on their few pages back there when someone bet huge amount and got profit here. It seems that you are new to gambling industry that makes you amaze on this kind of bet  Grin
0.25 btc per hand on blackjack actually very high amount and i'm sure it was not all in bet which mean the players playing with plenty of bets use 0.25 btc for every hand and imagine if the players playing 30 times bets or more with it then i'm sure this players can be called as the whales in online gambling industry

I can make an assumption here that he is indeed a middle whale, because there is no way that I could bet 0.25 btc per games. This is too much for any normal players here. They can even bet this huge because of it is stake, I do not think that someone can bet this huge amount randomly on other sites. It must be really painful if they do not get paid. But on stake with really huge bankroll and with the same roof as primedice make this possible Grin


Its pretty much no different than any regular casino. Most of the people that go to a physical casino usually gamble a few hundred, maybe less than 5% or even 1% or so gamble in the 5 figure range.

Most people usually get paid on a Friday and blow their entire paycheck by Saturday. However the casino maybe makes $500-$1000 off those types of players. When some rich businessman gambles its usually in the 5 figure range and they usually have a special room for those betters. And it comes with huge perks whether they gamble or not. From what I heard they get a free hotel stay, free dinners and free excusions.

The casinos most revenue however is from the 95% that gamble less than 5 figures, because there are many of those people and since they are mostly gambling with scared money, they usually are greedy and fearful and the casino makes a profit off them. Someone who bets in the 5 figure range usually has a net worth of 7 figures and they gamble without greed or fear and usually end up winning, if not they do it for fun.
6306  Alternate cryptocurrencies / Mining (Altcoins) / Re: Is buying used R9 290X worth it? on: July 17, 2019, 08:06:45 AM
I was just looking for something related to these cards, in terms of price performance and capacity I am undecided

In my area I found some "offers" in the informal market (already used for mining, of course)
r9 290 4GB 65 $
rx 470 4 GB 75 $
R9 390x 8 GB 70 $
rx 570 8 GB 100 $
rx 470 8 GB 100 $

Some vendors say they have been used only for "games", come on ... I do not even think so. I would be encouraged to buy if any will go down for around $ 40 ...

they are usually double the price mentioned I suppose they will be desperate sale

In my area the pricing is pretty similiar. The RX 470 4GB resell value is very low probably because AMD made millions of those GPUs and almost all got bought by miners and now nobody wants them anymore.

The 8GB always goes for more because it has more memory and in certain newer and more intensive games it performs better. It also performs a little faster with ETH mining due to the faster ram.

The 290/390 pricing is similiar since they are power-hog type of GPUs and miners don't want them. And gamers might want them but due to the power issues they are noiser than say an RX 580 or some Nvidia 1070 GPU.
6307  Economy / Speculation / Re: 2017 Crash DejaVu? on: July 17, 2019, 07:59:52 AM
In 2017 we had 30-40% pullbacks that were around 4-5 weeks or so. And it eventually engulfed those drops and hit a new ATH shortly after.

The reason why the pullbacks are so severe is mostly due to over-leverged longs. Basically a few days ago when we were at $13000 there was over $1.1 billion in open interest and today its only $700, so its a crazy amount of longs which were liquidated that lead to this severe drop which happened so quickly.

It looks like the $9200 area held, so see if we can test the $10000 area and close above it.
6308  Alternate cryptocurrencies / Mining (Altcoins) / Re: Are core wallets programmed to freeze??? on: July 17, 2019, 05:26:14 AM
Its been years since I've actually run an actual Bitcoin core wallet but I remember a few years back I was getting freezing issues also. From what I've heard they might of been resolved by now.

I am not referring to the staking or mining with the core wallet but just running the wallet just to send and receive coins. The issue is mostly from not having enough system RAM and an SSD. The CPU doesn't really play a role, it only plays a role in the initial sync. But after you get it sync'd and if you got an old regular HDD and low amount of ram, it will freeze when it tries to open the wallet.

This is why most use online wallets or wallets like Electrum these days.
6309  Economy / Gambling / Re: Stake.com | The Most Popular Bitcoin Casino | V2 & New games out now! 👽 on: July 16, 2019, 08:31:49 AM

Not a fan of alts for gambling either. It WAS fun and seemed like a good idea at one time, now we all need to define digital money a lot better.


If you go to many of the gambling sites out there, people actually do place bets with coins other than Bitcoin. And right now its fairly cheap to send Bitcoin transactions, in the last 24 hours you could of sent a transaction with 1 sat/byte so basically a typical transaction could be as low as 250 sats if its 1 input and 2 outputs which is about 3 cents. However people still are using alts.

Gambling sites are realizing this and this is why they are adding alts, not because the bitcoin network is expensive to transact but because there are people out there that own coins other than Bitcoin.

So say there are 2 gambling sites, both featuring dice and say that one accepts Ripple and the other doesn't. Some gambler has a stack of XRP and doesn't own any Bitcoin, which site do you think they would deposit to? This way Stake would gain a customer.

This is the customers that they are targetting for. Many people sold their BTC since it quadruppled since the beginning of the year but many are still holding alts which didn't move by much.

6310  Economy / Speculation / Re: Bitcoin Dominance rising again. What is happening? on: July 16, 2019, 06:26:07 AM
There were 2 major price hikes in the history of bitcoin. One was the 2013 year and another was the 2017 year. Ethereum plays a major role in today's alt market since most of the shit coins are created out of ethereum network. 2013 weren't much affected with the shit coin losses since Ethereum was created only in late 2013 - early 2014. So people who came to know of the cryptocurrency market followed bitcoin and updated themselves with the tech in the later time. But the real problem started with the development of Ethereum and the formation of EEA. This was probably the reason which triggered various companies to learn a little bit of solidity code and create their coins out of thin air.

The event reached its peak by end of 2017 and probably people who came to know of cryptocurrency jumped onto alts in the verge of catching an earlier train. This fueled various companies and scammers to start their own coin. Once some of these companies collapsed, the 2017 newbies started realizing the real potential of bitcoin. This paved way for major selling in these shitcoins and the transfer of all their money to bitcoin.

Alts have the potential unless the start-ups don't scam and run away with investors money and similarly Ethereum is a good platform for bringing business into the blockchain if they are utilized in a proper way. The speculation of alts being the next bitcoin should come to an end and if that happens we would see the real potential coins which can solve the real world problems through blockchain cherishing over the period of time. People should become more educated and must have the capability of distinguishing a product based alt with a payment processing coin like btc.

I completely agree with this statement and it deserves a merit.

Basically the complete dump of BTCUSD to $9850 which happened yesterday was mostly due to ETH in my opinion. I was watching the charts and when ETHBTC started breaking yearly support areas, all hell started to break lose.

Most likely due to over-leveraged longs waiting for "alt season" there were 2 massive spikes in ETHBTC, which caused a dump in ETHUSD which caused a flash crash and this most likely contributed to the selling of BTCUSD.

Now it seems to have stabilized however there might be more dumps if ETHBTC breaks the 0.02 ratio.

Taking into account probability, you are better off starting the search from the middle of the range and spreading it outwards, however its not always the case.

2 Years ago when I tried to find #54 or #55, I tried it the same way and basically eventually gave up because ETH/ZEC mining was more profitable and when the key was finally found (by LBC if I recall) it was somewhere towards the end of the range, so I would of most likely never found it anyways.

Best would of been some type of pool for this, where if the key is found its equally distributed for all the shares submitted.
6312  Alternate cryptocurrencies / Mining (Altcoins) / Re: Is buying used R9 290X worth it? on: July 16, 2019, 06:11:18 AM
From what I recently learnt from a similar ancient GPU thread,
https://bitcointalk.org/index.php?topic=1540107.0

You can still mine ETH with the Hawaii GPUs however it won't work under Windows and/or with Claymore.

You need to use software like SMos or PhoenixMiner and you will get the full 30MH/s that everybody got in 2016/2017. I didn't realise this and pretty much almost got rid of my R9 290, however most likely in the winter months will power them up again.

6313  Economy / Gambling / Re: 🔶 YOLOdice.com 🔶 - fast and fair dice game - BTC LTC ETH DOGE on: July 15, 2019, 05:57:24 AM
Sometimes I play on yolodice. I noticed that yolodice supports some different cryptocurrencies, BTC ltc eth and doge.
I was thinking, why not xrp support? Xrp transactions are cheap and fast. Is it an upcoming feature? Are there other sites that support xrp to gamble?
It would also be nice to be able to exchange btc-xrp in yolodice plataform, as it already support somes exchange pairs
Hey there, according to Ethan in our chat the other day, he's not interested in adding any other coins at the moment, he said he's happy with the four we currently have, and would rather focus on new features in the future rather than more coins.  This is just what he said, I suppose he could change his mind, but I think his interest in XRP is very very low.

I think unless there are crazy bitcoin transaction fees like we had in Q4 2017, I don't think all gambling sites need to list many alts. Back in Q4 2017, it was very bad because I remember I had to pay $50 just to send 1 transaction which had 1 input and 2 outputs and it took probably 2-3 hours to confirm.

Right now bitcoin seems to be going mainstream again with the Trump tweet and the Facebook crypto-coin and the transaction fees are very low. You can probably send a transaction at 5 sats/byte if done on the weekend. This was not possible back in 2017.

I don't think its Segwit, I think its more of the transaction spamming that stopped and seems not to have an affect this time like it did in the last bull market.
6314  Economy / Speculation / Re: Bitcoin seems to drop faster than rises on: July 15, 2019, 05:45:41 AM
Its not only bitcoin or crypto markets that crash faster than they rise, its almost all markets especially the stock markets.

Look at the stock market back in 2007-2008 during the recession, it took years for the markets to hit those highs and only took around 1.5 years for all the profits to vanish.

Markets goes up slower than they go down mostly due to fear. Basically when the market is up 5% everybody is happy, when the markets are down 20% or so, people panic and everybody wants to get out at the same time. So there is massive selling pressure that accelerates everyday and everytually there is a recession.

Then it hits a low and the cycle repeats. This is generally how the rich and other institutions make their millions. Off the traders who sell out of fear not to lose money.
6315  Bitcoin / Bitcoin Discussion / Re: Bitcoin puzzle transaction ~32 BTC prize to who solves it on: July 15, 2019, 05:41:58 AM
Where can i buy VPS with Nvidia Tesla or any other good GPU and hourly plan?
Found parsecgaming . com but not sure if is working, anyone tested them, can i use BitCrack on their servers?

Thanks

Bro i advise you to stop wasting you money, for fast bucks ( puzzel ) because  the hashing power which is required to solve one piece is very big, with the money better buy shitcoins, or rennt hash power for mining. But if you know how to use baby step giant step algo just buy amazon server with big amount of ram and go on it Smiley  Also feel free to send me tip xD (just kidding)


So how we calculate specific hex range for 64 for example and the possible variatons of 64 is calculated  2^65 - 2^64 = right ?

Edit: Is it have someone who have for example all 22 bit adresses generated and checked for funds ? Maybe have more puzzels or adresses  in these ranges with funds ?



Interesting, what speed you have on what video card? I have rx560oc and reach only 50Mkey/s acording my calculation if you scan all 62 bit range is so much years. Are you scan small pieces of 62bit range or all ? Thanks


Edit: Sorry for my bad english,it isnt my native language.

Do you know what speed an RX 570 would get approx with Bitcrack? I had no idea it worked on AMD, assumed it was Nvidia only.

I remember when this thread first was opened, I was using vanitygen to find the next key, at the time it was #55 or so. I had to manually update the code so the increments wouldn't be randon instead it would be incremental. And finally got it to work.

With my R9 280X, the most I Could get was like 20MH/s, if I overclocked then I think I got 21MH/s. So its pretty impressive that your RX560 can get 50MH/s since it has much less cores than an actual RX 570.

Vanitygen was not a good program because it wasn't meant for searching incremental private keys, it was used to find vanity addresses instead. Bitcrack was more geared towards this thread. However it was released maybe a year or 2 after this thread was discovered and was too late for most of the earlier keys.


Wow you get with r9 280x 20mh or 20 Milion Keys/s . I dont think you can get only 20mkey/s thats pretty small try to play with -b and -t  - p parameters  try something like this  -b 32 - t 256 -p 1024 and post results. Also my list have only 255 adresses of the puzzel and use -c ( compressed mode) its seems when you put so much adresses the speed drops hard. Also update you amd drivers to last .

Offtopic: Someone who know VHDL here , please tell me is it possible fpga adoption of bitcrack algo ? And if it possible with Xilinx Virtex-7 FPGA VC707  what speed can get ?

It was 20 Million keys per second. But this wasn't this Kangaroo hop program or Bitcrack, this was just with Vanitygen.

Basically the R9 280 and R9 290 both got around 20MH/s, if you had another GPU however in the same rig, it ran at like 15MH/s, and if you had a 3rd GPU it ran at like 10MH/s. It was very buggy also and crashed alot.

Basically had to download the source myself and mod it and probably didn't do a good job. But even 2 years back, or when the 55 key was being solved, it was more profitable to mine ETH or ZEC so I just switched to that.

r9 290/390 give 29-30 mh/s while mining on Ubuntu. For a serious increase in performance, you have to use Ubuntu version no higher than 16.04 (with new Ubuntu kernels these cards have poor compatibility). You have to install driver version 17.40 and AMD SDK kit. Switching to Linux-like OS gives additional 10 mh/s (50%). There is a guide how to do it (in Russian): https://www.cryptoprofi.info/?p=3313. Ubuntu will be useful for mining on all old cards including R9 280, 290, 295 and 390.

I will give Ubuntu a try for these old cards. But how about rx 470 / rx 570? Will they also have higher hash rates with Ubuntu?
not just linux, it's the AMDGPU-Pro driver improving things. I was testing an old HD 7850, gets 10-13MH/s on windows and FGLRX on linux, but AMDGPU-Pro on SMOS got me 17-17.7MH/s. HiveOS just refused to use the 7850. SMOS and HiveOS both got me about 27-30MH/s for an R9 290, but only 19-20MH/s on windows. My RX cards were the same on linux distros in general. The RX Cards were the same on linux and windows with compute mode enabled*. linux was doing the same thing as the compute-mode by default, I believe AMDGPU-Pro is basically defaulting to compute-mode behavior for all GCN cards while windows only uses that behavior on GCN3 and up.

It depends what coin you are mining on Daggerhash.

You said you got 7850 running at 13MH/s, since every 7850 has max 2GB of ram you most likely are mining some extremely low DAG coin like Expanse.

So with DAG #0, an R9 280X can mine at 27MH/s and an R9 290 can mine at 31MH/s. I know because it was there when ETH had low DAG numbers.

However you can't mine ETH with an R9 290 at 30MH/s anymore, because sometime last year when the DAG increased the speed slowed down and you get like 15MH/s or less with the R9 290. With the Pitcairns or Tahiti's you can't even mine ETH.

You can mine those other coins but their profitability is way low. And ETH profitability is not that great either. So no point in using those GPUs. Just sell to gamers instead and get a cheap RX 470.
One of my R9 290s is mining ETC at 29.8 right now, on SMOS. 1040 core, 1250 memory. My other is doing 28.2 at 977mhz core 1250 memory (these are the cards stock settings from factory). edit: I do have ref set to 40 on both, but I don't believe it makes a difference with how much bandwidth they just naturally have, so have it set Just Because.
The 7850 was mining Callisto on SMOS at 17MH/s before it got just a little too big to fit even on linux, the 13MH/s I managed on windows was with a wildly OC'd core and memory with callisto. Expanse was about the same as callisto, Ubiq did better with its smaller DAG (I think its ethash is also a slight modification over normal?? Still don't know for sure). On ubiq I still got 17 on linux, but was able to pull 18MH/s on windows with a high OC.

Hmm, I did not know this.

So basically the Hawaii slowdown with the DAG is not related to the GPU architecture but to the operating system and drivers being used.

Thanks for telling me this, I might dust them off and power them up again if I can get close to 28MH/s. Really surprised nobody has mentioned this before on the Claymore thread. Tons of people complaining why their 290/390 is slowing down and nobody could figure out the issue. Most just eBay'd or Craiglisted their R9 290 and got an RX 470 instead.

If ETH can get back above the $300 area again then with the huge power hog that the R9 290 is, it still might be a little profitable. The Reference design is rock-solid built and very stable at any temps.
I'm using phoenixminer myself. I found it odd that I've only found 1 other person that seemed to realize the old GCN1 and GCN2 cards work so much better on (modern) linux for pure stock, and they were mining ubiq on a rack's worth of the same powercolor HD 7850 I have, tuned to ~90W and 17MH/s. I have yet to see how Tahiti cards do, but I really want to know now that I've seen Pitcairn and Hawaii do so well.

I don't know about the Hawaii but I do know that the Tahiti and the Pitcairn running under Ubuntu suffered the same DAG thrashing bug on Linux as it did with Windows. This was with the Claymore miner and using various AMD drivers.

This however was a long time ago, probably about 2 years ago and I haven't tested it since. Maybe out of pure boredom I will test out the Tahiti's using PhoenixMiner on some low DAG # coin and see what the results are.

90 Watts is pretty good however are you sure its accurate. I remember my Tahiti's back in 2016 mined at 20Mhs and used exactly 200 Watts each.

Expanse was about the same as callisto, Ubiq did better with its smaller DAG (I think its ethash is also a slight modification over normal?? Still don't know for sure). On ubiq I still got 17 on linux, but was able to pull 18MH/s on windows with a high OC.

Hmm, I did not know this.

So basically the Hawaii slowdown with the DAG is not related to the GPU architecture but to the operating system and drivers being used.

Thanks for telling me this, I might dust them off and power them up again if I can get close to 28MH/s. Really surprised nobody has mentioned this before on the Claymore thread. Tons of people complaining why their 290/390 is slowing down and nobody could figure out the issue. Most just eBay'd or Craiglisted their R9 290 and got an RX 470 instead.

If ETH can get back above the $300 area again then with the huge power hog that the R9 290 is, it still might be a little profitable. The Reference design is rock-solid built and very stable at any temps.

Where can i buy VPS with Nvidia Tesla or any other good GPU and hourly plan?
Found parsecgaming . com but not sure if is working, anyone tested them, can i use BitCrack on their servers?

Thanks
At amazon

But they allow this kind of activities also maybe google cloud? saw that i can install the drivers on amazon aws but they may request account verification, any other good option with windows and drivers already installed? Thank you

Last time I heard Google cloud doesn't like when you use their hardware for anything related to Crypto mining. Amazon AWS doesn't have issues neither does DigitalOcean.

However if you are a new account, you will be limited due to the issues they had in the past with fraud. So for a month or 2 there is a limit of how much servers you can rent. After a few months the limits go away, but you need to be verified because you need to pay by your credit card.

I find it effective to reduce stale shares is if you connect to pools within your region. Connecting to the mining server most near to you will reduce it.

I also find it effective if you use a CL15/16 type of RAM in your motherboard.

A SSD is also preferable than a standard HDD.

Lastly, if you can, avoid connecting your rig via WIFI donggle.

Your first point is correct but the latter 3 will not make a difference.

The type of RAM in your computer makes no difference what so ever, do you know how ultra fast RAM is these days?

The SSD has nothing to do with stales shares either, the miner runs off the memory pretty much.

The wifi could be true however WIFI is very fast these days and unless you got interference it won't slow you down by much.

Your point is correct regarding the region. Basically if you are in asia, find a pool located in Asia. If you are in USA, find a pool located in USA. Most pools have multi-regions these days so it shouldn't be an issue.

r9 290/390 give 29-30 mh/s while mining on Ubuntu. For a serious increase in performance, you have to use Ubuntu version no higher than 16.04 (with new Ubuntu kernels these cards have poor compatibility). You have to install driver version 17.40 and AMD SDK kit. Switching to Linux-like OS gives additional 10 mh/s (50%). There is a guide how to do it (in Russian): https://www.cryptoprofi.info/?p=3313. Ubuntu will be useful for mining on all old cards including R9 280, 290, 295 and 390.

I will give Ubuntu a try for these old cards. But how about rx 470 / rx 570? Will they also have higher hash rates with Ubuntu?
not just linux, it's the AMDGPU-Pro driver improving things. I was testing an old HD 7850, gets 10-13MH/s on windows and FGLRX on linux, but AMDGPU-Pro on SMOS got me 17-17.7MH/s. HiveOS just refused to use the 7850. SMOS and HiveOS both got me about 27-30MH/s for an R9 290, but only 19-20MH/s on windows. My RX cards were the same on linux distros in general. The RX Cards were the same on linux and windows with compute mode enabled*. linux was doing the same thing as the compute-mode by default, I believe AMDGPU-Pro is basically defaulting to compute-mode behavior for all GCN cards while windows only uses that behavior on GCN3 and up.

It depends what coin you are mining on Daggerhash.

You said you got 7850 running at 13MH/s, since every 7850 has max 2GB of ram you most likely are mining some extremely low DAG coin like Expanse.

So with DAG #0, an R9 280X can mine at 27MH/s and an R9 290 can mine at 31MH/s. I know because it was there when ETH had low DAG numbers.

However you can't mine ETH with an R9 290 at 30MH/s anymore, because sometime last year when the DAG increased the speed slowed down and you get like 15MH/s or less with the R9 290. With the Pitcairns or Tahiti's you can't even mine ETH.

You can mine those other coins but their profitability is way low. And ETH profitability is not that great either. So no point in using those GPUs. Just sell to gamers instead and get a cheap RX 470.
