Hi,
First of all, I don't have any issues like lost coins, etc, I'm just looking for some detailed information:
1. Where exactly are private keys and other application files stored (Android 4.3)? There is no /data/data/de.schildbach.wallet/ folder on the device (looked for ../data in device storage and sd card).
2. When this app is uninstalled from a device, does it make complete cleanup, deletes all private keys, etc?
Thanks for answers.

Hi, I'm selling 4x AntMiner S3+ ( no PSUs!). Bought directly from Bitmain approximately 1 and a half years ago. In excellent condition, fully working at full speed, they were all hosted in a datacenter. I prefer to sell them all 4 together, but will also sell them one by one. Will only ship to Europe, no other continents, in original package. PM with your offer. edit: SOLD

So ... In about 7 days (today is Feb. 11th 2016) we'll see a next difficulty re-target, probably with approx. +25%. The last seven re-targets were 9+18+11+9+6+20+25 (including the next one) which brings us to approx. +100%. That is, Bitcoin mining profit will be halved compared to just November 2015. Price in November 2015 was just about the same as now is (approx $400). This is a nice market and mining indicator. My prediction is that the reward halving, coming this summer will most probably have no significant effect on mining difficulty nor the prices. Sure diif will probably swing up and down a bit, prices as well (mostly because of media attention) but nothing big. The "halving" is happening all the time  Just my 5 cents

We at NiceHash.com are always striving to give you innovative and cutting edge technologies. Now we present our finest innovation: NiceHash Best Profit Auto-Switching Multi-Algorithm Mining. BPASMAM represents a new era in GPU mining. With the recent expansion of new algorithms GPU miner finds it hard to track which is the most profitable algorithm. Also, switching between various mining software and configuration files is very time consuming and inefficient. On the other hand there are many cloud mining users who would like to mine various coins, based on various algorithms and are willing to pay premium price for on-demand cloud mining with massive hashing power for a particular coin. NiceHash brought a solution to GPU miners as well as cloud mining users. Our best profit auto-switching multi-algorithm mining mode provides careless operation and highest profits for GPU miners and on-demand cloud mining of a particular coin for cloud mining users (buyers of hashing power). NiceHash BPASMAM calculates the currently most profitable algorithm based on current orders at NiceHash.com. If GPU miners uses our auto-switching ports, then sgminer will automatically switch to the most profitable algorithm. With this new feature hashing power buyers have the opportunity to actually reconfigure GPU miners by submitting best-paying orders of a volume high enough for a particular algorithm – and miners will gradually be reconfigured and switch to best-paying algorithm and thus fill the best-paying orders for a particular algorithm. Profitability recalculation is done on a 10-minute interval. You can get more information here: https://www.nicehash.com/multialgo/

Hi, At NiceHash.com (I'm sure you've already heard about us) we're running a multi-algo cloud mining service and multipool. Thus we're striving to get unified and feature-full GPU miner. That's why we've sponsored the integration of sph-miner + keccak (from cgminer) + x11_mod (from lasybear) + NIST5 algo and some more stuff into unified, runtime-kernel-switching new version of the original official sgminer. sgminer has since then been redefined from "scrypt-miner" to "GPU OpenCL miner" and thus strive to support wide range of algorithms for GPU mining. New algorithms are added over time as well as some new features. For the record: I'm not a developer of sgminer and haven't contributed any coding for sgminer, but was active in proposing and coordinating new features development. All the credits go to the many sgminer developers, listed here: https://github.com/nicehash/sgminer/graphs/contributors. NiceHash organization took over the initiative to continue development on this widely spread open-source mining software, therefore the most recent source code and releases can be found in the information below. SOURCE CODEIf you wan't to pull the source code from GIT you can do it with this command: git clone --recursive https://github.com/nicehash/sgminer.git RELEASESBinaries downloads are available here: https://github.com/nicehash/sgminer/releasesHere you can see the major changes: https://github.com/nicehash/sgminer/blob/master/doc/configuration.mdhttps://github.com/nicehash/sgminer/blob/master/doc/kernel.mdNews: https://github.com/nicehash/sgminer/commits/masterPlease note: sgminer is still in development, you should regularly, so there are might be still some open issues and minor bugs present. Here is an example of multi-algorithm configuration (you can add many pool-specific options): { "pools" : [ { "name" : "NiceHash_X11", "url" : "stratum+tcp://stratum.nicehash.com:3336", "user" : "btc_addr", "pass" : "x", "nfactor" : "10", "algorithm" : "darkcoin-mod" }, { "name" : "NiceHash_X13", "url" : "stratum+tcp://stratum.nicehash.com:3337", "user" : "btc_addr", "pass" : "x", "nfactor" : "10", "algorithm" : "marucoin-mod" }, { "name" : "NiceHash_SHA3", "url" : "stratum+tcp://stratum.nicehash.com:3338", "user" : "btc_addr", "pass" : "x", "nfactor" : "10", "algorithm" : "maxcoin" }, { "name" : "NiceHash_Scrypt-N", "url" : "stratum+tcp://stratum.nicehash.com:3335", "user" : "btc_addr", "pass" : "x", "nfactor" : "11", "algorithm" : "zuikkis" }, { "name" : "NiceHash_Scrypt", "url" : "stratum+tcp://stratum.nicehash.com:3333", "user" : "btc_addr", "pass" : "x", "nfactor" : "10", "algorithm" : "zuikkis" } ] "failover-only" : true, "failover-switch-delay" : "300", "queue" : "0", ... other configuration settings ...
Of course you can choose any and as many pools you prefer, NiceHash.com pools were given just as an example. Your miner will be able to switch to different pools using different algorithms at runtime, without any interruption and without sgminer restart. You can also set GPU settings and some other settings at a per-pool level to get optimum performance on various pools with various algorithms with a single configuration file. Now you can mine Litecoin, Dogecoin, Vertcoin, Darkcoin, Maxcoin, MaruCoin ... you-name-it with a single unified sgminer. Note: sgminer v5 intoduced new stratum extranonce subscription; some pools ignores connection when sgminer sends extranonce subscription request, therefore you just have to add "no-extranonce" : true setting to the pool config for pools, that doesn't support extranonce-subscribe - this kind of pools appears Dead even if they are suposed to be working fine (you should never use this setting on nicehash pools since nicehash stratum proxy provides better efficiency with extranonce subscription) { "url" : "stratum+tcp://some-pool:3333", "no-extranonce" : true, "user" : "username", "pass" : "x", }
Or if you're using command line options, example for quark mining: sgminer --algorithm quarkcoin --no-extranonce -I 18 -g 1 -w 256 -o stratum+tcp://some-quark-pool:3333 -u ... -p ... All interested developers, please, feel free to contribute to the code by simply pushing Pull request to the Github repository (see above). Again, thanks to all the great developers of sgminer and kind regards, kenshirothefist

If you haven't already heard - there is a new service out there, allowing you to earn more with your rigs! Why use NiceHash for selling your hashing power? A couple of things to stress out: - simple as using a multipool (no registration, no contracts, no bonds to either hash power buyers of NiceHash service) - be paid more than multipool pays - automatic payments in Bitcoins 4 times a day (so you can jump in to good payout very quickly) - no limits - use as many rigs as you like - textual and graphical statistics I really welcome you to check on FAQ's. I would especially recommend these selected topics: General: How exactly does pay-per-valid-share and get-paid-per-valid share work? http://nicehash.com/index.jsp?p=faq#faqg2Rig providers: sellers: Which miners are supported? http://nicehash.com/index.jsp?p=faq#faqs0How can I configure my miner to work with NiceHash service? http://nicehash.com/index.jsp?p=faq#faqs1I have slow mining rig. Can I adjust difficulty? http://nicehash.com/index.jsp?p=faq#faqs7Can you help me with transition to sgminer? http://nicehash.com/index.jsp?p=faq#faqs8So, just give it a try, point your: Scrypt miners to: stratum+tcp://stratum.nicehash.com:3333 Or SHA256 miners to: stratum+tcp://stratum.nicehash.com:3334 Or Scrypt-Adaptive-Nfactor miners to: stratum+tcp://stratum.nicehash.com:3335 Use your Bitcoin address as username. Use any password you like. There are already orders on NiceHash waiting for your hash power! Here is link to official ANN thread: https://bitcointalk.org/index.php?topic=562238.0

Problem: I have multiple rigs and I often switch different cgminers to be able to mine coins based on various algorithms (regular scrypt, scrypt-adaptive-nfactor, keccak sha-3, etc). I also lease my rigs on LeaseRig and customers often requests to switch a particular rig or all of them to a particular algorithm. Solution: Make a simple back-end script and a simple web interface to be able to do all this with a single button click. Oh yeah, let the dreams come true! --- So, basically I made a simple web page, actually a web wrapper to control my Linux based multi-mode rigs. This solution is only for Linux rigs (I guess the majority of serious rig providers are running some sort of Linux on the rigs anyway) and requires some Linux knowledge to properly set-up the environment. With this solution rig provider can control his rig's "mode" remotely solely with web browser. The system consist of one shell script that handles cgminer "mode" via screen sessions and one php web page to control rig's "mode" - this php web page basically just calls the underlying shell script. Apache or some other webserver must be running on the rig (just basic install of apache is good out of the box with defaults). To be able to support Windows rigs one would have to write some kind of whatever script/app to be able to start/stop different cgminers (different forks of cgminers) in windows - I have no idea how to do this; but one could re-use the php web app on Windows rigs as well. See demo video. This video shows how this script is stopping one cgminer and switches to another cgminer or vertminer or whatever. Keep in mind that this script switches cgminer and also (optionally) changes all the needed config at LeaseRig (see also the other demo below): Video DEMO: http://files.kobal.org/caveminers/cgminer_switcher_demo.m4vFurther more, I made another php wrapper that enables me to switch mode for all my rigs at once, just with a single button ... this one actually just submits proper POST data to each rig's php web wrapper, see the demo here (this demo doesn't show cgminer, but cgminer is switching in the background just as it is on the previous demo): Video DEMO: http://files.kobal.org/caveminers/cgminer_multi_switcher_demo.m4v--- Things to keep in mind: - currently only Linux rigs are supported- this let's you change rig's cgminer instance as well as LeaseRig rig's configuration (type, speed, description, pools)--- These scripts are in beta development. I'm not responsible for any kind of issues due to cgminer failures or errors! USE AT YOUR OWN RISK!But if you like it, consider dropping a few mBTC to 1LfFJV321RKeUmhRAf9T5VXKreX7Zdm4y7 ... Thanks! --- Quick (and dirty) how to (repeat this steps on each of your rigs): http://files.kobal.org/caveminers/cgminer_switcher_README.txtget the shell script here: http://files.kobal.org/caveminers/cgminer_switcher.sh.tar.gzget the web scripts here: http://files.kobal.org/caveminers/cgminer_switcher_php.tar.gz--- btw: here you can grab some Linux compiled versions of cgminer (and it's forks): http://files.kobal.org/cgminer/cgminer-3.7.2-kalroth-20140204-LINUX.tar.gzhttp://files.kobal.org/cgminer/cgminer-3.7.3-kalroth-keccak-LINUX.tar.gzhttp://files.kobal.org/cgminer/cgminer-vertminer-gpu-LINUX.tar.gz

Hi,
I'm seeking for experts on cgminer WU.
So, the cgminer WU is the Work Utility defined as the number of diff1 shares work / minute (accepted or rejected).
Please, correct me if I'm wrong. To get the most of my miner, I should optimize my miner to get the highest possible WU (because this is what is actually committed to the pool and thus makes money). In some cases you can get more WU with actually lower hash rates on GPUs. There are different approaches to accomplish this (decreasing intensity, increase/decrease thread concurrency).
Now, to my example: I have miner with 4x XFX R9 290 (all the same, all with the same settings 1015/1500/20481), resulting like this (running for 15 hours):
(5s):3.493M (avg):3.487Mh/s | A:2235392 R:48128 HW:0 WU:3097.8/m
GPU 0: 77.0C 5150RPM | 872.0K/872.6Kh/s | R: 3.0% HW:0 WU:747.8/m T:1 I:19 GPU 1: 80.0C 5250RPM | 873.2K/871.9Kh/s | R: 2.3% HW:0 WU:805.2/m T:1 I:19 GPU 2: 75.0C 5153RPM | 873.2K/871.8Kh/s | R: 3.0% HW:0 WU:736.3/m T:1 I:19 GPU 3: 77.0C 5171RPM | 872.9K/871.9Kh/s | R: 0.3% HW:0 WU:805.4/m T:1 I:19
So, the average WU / hashrate for the whole miner is 3097.8 / 3.487 = 88,8%
However, each card has a very different WU / hashrate:
GPU 0: 85,8% GPU 1: 92,2% GPU 2: 84,3% GPU 3: 92,3%
I know that the WU is dependent on luck finding valid shares on each GPU, but this should stabilize in time. Now, why are there such differences between the cards? Are you experiencing the same thing? Is there any general rule to get the same WU on all cards? Any hints on optimizations to get the highest possible WU?
Thank you!
