I have 7850 graphics card. Can I mine DOGE? Will it be effective? What do you suggest?
your best bet would be an scrypt ASIC. As a reference: https://bitmakler.net/asic you can look for SCRYPT asics from this list. They should give you the best performance instead of GPU or CPU. That being said, theoretically, you should be able to mine with a GPU, according to this list: https://litecoin.info/Mining_hardware_comparison , your card should hash at a rate between 300 and 400 kH/s. Compare it to the asics in the above list and see the difference  EDIT: do be carefull with the list of bitmakler, next to listing legit asics, i have just noticed he also lists scams/hoaxes... If you ever want to buy an asic, it would be best to find a more trustworthy seller's list |

actually my GPU is pretty decent. I was thinking more about GPU mining...
A decent GPU on a laptop, are you sure? Usually, the GPU's in laptops are not worth mining with. |

Basically, either download and compile blockparser, or download and install ABE...
The second option will allow you to parse the blockchain and put everyting in a nice relational database...
The parsing itself takes weeks tough. Weeks? Are you joking? Take this code. It parses the whole bitcoin blockchain ( 630 blk-files 128 mb each ) in less than an hour. (Of course, the parser does no ECDSA verification and SHA256d checking ) #include <QTimer>
#include <QFile>
#include "BlockChain.h"
BlockChain::BlockChain ( const int start, QObject* parent ) : QFile ( parent ), blkFile ( 0 )
{
QTimer::singleShot ( 0, this, SLOT ( start ( ) ) );
}
//--------------------------------------------------------------
void BlockChain::start ( )
{
setFileName ( blkFileName ( blkFile++ ) );
if ( !open ( QIODevice::ReadOnly ) )
{
_trace ( QString ( "cant open [%1]" ).arg ( fileName ( ) ) );
getParent ( ).block ( QByteArray ( ) ); // quit signal - empty block
deleteLater ( );
}
else
{
_trace ( QString ( "processing [%1]" ).arg ( fileName ( ) ) );
QTimer::singleShot ( 0, this, SLOT ( next ( ) ) );
}
}
//--------------------------------------------------------------
void BlockChain::next ( )
{
bool lock ( true );
if ( pos ( ) < size ( ) )
{
quint32 magic;
quint32 size ( read ( (char*)&magic, 4 ) );
xassert ( ( ( magic == MAGIC_ID ) || !magic ) && ( size == 4 ) );
if ( magic )
{
read ( (char*)&size, 4 );
xassert ( size > HEADER_SIZE && size <= MAX_BLOCK_SIZE );
getParent ( ).block ( read ( size ) ); // callback to block parser
QTimer::singleShot ( 0, this, SLOT ( next ( ) ) );
return;
}
else
lock = false;
}
close ( );
getParent ( ).doneFile ( lock, blkFile - 1 ); // callback about eof
QTimer::singleShot ( 0, this, SLOT ( start ( ) ) ); // goto next file
}
//--------------------------------------------------------------
const QString BlockChain::blkFileName ( const int i ) // [inline static]
{
return
( i < 10 ) ? QString ( DATA_ROOT "\\blk0000%1.dat" ).arg ( i ) :
( i < 100 ) ? QString ( DATA_ROOT "\\blk000%1.dat" ).arg ( i ) :
QString ( DATA_ROOT "\\blk00%1.dat" ).arg ( i );
}
This script would be even better than my sollution (untested)... I'm not joking tough, building the ABE database takes weeks... It's a slow, single thread, process that executes one insert at a time... In the end, you do have a nice relational database which you can query any way you like.... It's huge tough. The other sollution i proposed (compiling blockparser) is also a lot faster, it runs a couple of hours to parse everything, but you end up with a big dumpfile filled with results. I don't think you can use it to generate a nice database. |

I have 6 units SP20 miners connected to sha256 on nicehash.com. How do i switch to another algorithm like neoscrypt. Please help me someone.
It's not possible to mine neoscrypt coins with an sha256 ASIC i'm afraid. Basically, you've bought a machine that was built for the sole purpose of generating sha256 hashes as efficient as possible, it cannot be converted to generate other hashes... |

How about miners that have wifi built in? I don't need to install this thing at my desk necessarily...
Also - I'm not planning on stealing electricity. Our Company gets a fairly significant discount on kW.
Well... If you're not stealing, you could potentially just do the math... Look for deals on the forum, see how much the hardware would cost (include import tax and shipping), puch in the miner's specs and cost in the coinwarz calculator: http://www.coinwarz.com/calculators/bitcoin-mining-calculator Add about 20% to the current diff, just to be sure, and see if you'd roi in 6 months... If you have the hardware payed back in 6 months, i would go for it, if not, i wouldn't even consider starting. This being said: you'll need dozens of sidehack compac's to even start mining, if you run just one, it'll take you months before you have enough satoshi's to ask for a withdrawal. I've done the math for a single compac, running at 16 Gh 24/7 at diff + 20% without any power cost, hw cost or pool fee: http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=16&p=0&pc=0.0&pf=0.00&d=270999446615.46000000&r=12.50000000&er=620.72590000&hc=0.00This basically means that if you're paying more than $1.5 for a compaq, i personally believe you shouldn't have bought one. I really like compac sticks, but i see them as more of a learning tool, or as a way for a private individual to help secure the network (even in a tiny way), and not as a means to make money... I've seen some people selling old S1-S5's for very reasonable rates... Those things could actually ROI on free electricity, but they're big and loud. For example, and S5 running at 1155 Ghs, could potentially mine around $240 a year (if the diff doesn't rise to much, and the btc price remains steady) http://www.coinwarz.com/calculators/bitcoin-mining-calculator/?h=1155&p=0.00&pc=0.00&pf=0.00&d=270999446615.46000000&r=12.50000000&er=620.72590000&hc=0.00 I think it would be possible to pay around $150 for one, and make a profit... Albeit, you defenately don't want to run one in the office |

Gekko sidehack stick? You're wasting your time though, they're toys. Not really ROI-able. I like mine, but its not something i'd(or could use) use to steal electricity from work and make money.
I've seen some people claiming that you could potentially mine 2 PPC blocks a year with a sidehack stick, making it borderline efficient... That being said, i have one laying around, havent plugged it in in months because i could run it profitably with my energy rate. I think the main question you have to ask yourself is: is it worth risking your job to mine a couple bucks worth of BTC (or PPC) a month? |

I think he already know now that it's not good for your device to mine with it. But when you feel the need to try it out and don't care if your device could be damaged you can try Coin Miner Pro. I tried it last year and it worked fine you can actually mine with it. Search with google if you want the paid app for free.
True, but in that case, i'd advice the OP to invest five or ten bucks and buy an antminer U2 or a geccoscience compaq. Those sticks will deliver hundreds, if not thousands of times the hashpower of a cellphone, and they're made for mining (in other words, they won't break because you mine with them). Be carefull tough: neither mining with those sticks, nor mining with your phone will make enough coins to even withdraw from a mining pool... It's all just for learning or lotto mining (at least, when mining bitcoin. Apparently, you could try to mine PPC with an usb asic) |

You understood everything !
To have a good note my mining plant must be profitable , I live in France so the bitcoin is not profitable but at the ETH profitable air it, I have no starting material , I think I can invest about $ 80 / $ 100 at the beginning in my little setup
$100 won't get you very far I'm afraid. You could try to buy a second hand antminer on this forum, but as a fellow European, I can pretty much guarantee they won't make any profit (we pay to much for our electricity). Basically, if you spend $100 on mining gear, it might take you more than a year before you mined $100 worth of btc, and if you subtract the power cost you'll make negative profit. I guess your best shot would be to buy a second hand GPU (read up on which GPUs to buy in the altcoin mining subforum). It will be very difficult to make profit tough |

If you do decide to export the private keys and import them in electrum (I don't think multibit HD allows the importing of private keys), make sure you export the keys for all the addresses having inputs. If you only generated one address, you should be fine, if you generated more: be cautious. Since you didn't use the wallet to send funds, I don't think there would be change addresses, so you shouldn't have to worry about those either.
Also, if you export your private key, consider your wallet to be exposed
Last but not least: backup your wallet.dat , even if the wallet shouldn't contain any more funds
I would also suggest to just wait it out if that's possible

So, am I getting this correctly:
You are a student, and as a project you want to make a profitable mining setup using a raspberry pi...
To tell you the truth, to even have a tiny chance of making a profit, you'll need really cheap power, a free raspberry and a budget to either buy 1 or 2 decent GPUs, or a reasonably recent asic.
Can you tell us about your budget, power cost and hardware you already own/can get for free

I suggest you post this question in your your own language in your local subforum, and ask somebody to help you with a translation, because I really can't understand your question. Hello everybody!
I come here to ask some questions!
I am in IT license and we have a project of the end of year or we have to present a computer system ( a " machine " ) original with my group one to decide to make discover the ETH or the Bitcoin because we speak about it very current very in class)!
I know the bases of the mining, therefore, to limit the knocks I had the idea to mine(undermine) with Raspberry Pi 3 and on the verge of cards(maps) Asic nevertheless it is there that I need you.
I would like that my mining is profitable (the note will only be better because our professors channel already) I would have the objective to clear(release) a light profit (I me in madman of 300$ a month I am conscious that this period isover even if it is 5$ his would be a victory, I think of mining of the ETH.
But I have difficulty in calculating, and I owe you admit that we do not have a big material budget (the studies his pay not!) of the blow I would like to know if you would have a young setup lowcost with Raspberry Pi 3, 1 or 2 key, an ali ' and a small basic screen, just to enjoy rising quite his, it is me who accommodate the whole and I have one 20mē
Thank you in advance for your help!

Yes, you can mine bitcoin through your android phones or smartphones. There's an app in playstore that can help you in mining bitcoin. But the thing is that don't expect too much from your phone because mining bitcoin is not an easy task to do just using your phone, because it requires fast GPU and some mining hardware's that is being used in solving algorithm or mathematical problems to earn bitcoin in every algorithm you solved. It will be easier if you will use a high end PC because it's a lot more faster than a smartphone, and PC have longer battery life than smartphones so it have more advantages using it in mining than using smartphones.
Please, don't advice anyone to mine bitcoins with their "high end PC". It's a waste of resources. Even the best pc, with the best GPU cannot compete against an older ASIC. The diff is so high, you'll burn your pc long before you make enough coins to withdraw from a pool... |

Please how can I mine Bitcoin with my phone, is it possible, please someone should lend help.
Definitely not. You'll just burn down your phone. There is no way it can support mining of even an altcoin ( except the mangocoinz mining concept) . You'll break your phone even before earning enough to pay for the electricity you used the whole yime you mine in it. If you want to mine, atleast use a laptop with good specs. agreed, only wanted to add mangocoinz is dead, and mining with a laptop isn't a good idear either... You can mine some selected altcoins with a good GPU, or maybe some CPU minable coins with a decent desktop, but mining with a laptop is a bad idar IMHO. Since this is the bitcoin mining subforum, i'd have to conclude you'll need a latest gen ASIC to mine bitcoins and make profit (if you're lucky, you can even mine at a loss with the latest gen gear) |

I want to share my bitcoin dice strategy. You need 0.01 btc, Bet Chance 50% to 55%. Try to bet (Your 1st bet) 0.0001 btc, If lose bet 0.0002, if lose again 0.0004 if lose again 0.0008, if lose again 0.0016, if lose again 0.0032 btc. Once you win back your bet to 0.0001 btc. Slowly but surely. Hope this strategy helps.
what if we never win ? it is possible in gambling that sometimes you divide your bits and bet more and more but everytime you may get unlucky. also, this is not a strategy. i think that every gambler in their positive mind plays in the same way in dice games. btw, you cannot have a good strategy in dice games unless you are a cheater ofcourse. I want to bring back those questions to you, What if you never Lost? Hahaha, Just try this strategy and come back here and tell me what happens on my Strategy  This strategy not only in bitcoin dice, but also in all kind of gambling games. This is Bet Strategy I'm not a betting man myself, but that just sounds like the description of martingale... A strategy that has been used, and discussed on this forum for many, many times  You can use the searchfunction and see what others have to say about it.... Some really like it, others say it's not that good. |

IMHO, bitcoin wasn't designed to be anonymous, however, you can always achieve a reasonable amount of anonimity by combining a couple of methods... If you combine enough methods, it becomes virtually impossible to trace coins back to you...
For example, if you combine some of these things, over a secure VPN/Tor/proxy server (or a combination)
- one, or even better, several mixers
- exchange BTC to monero or a cryptonote-based currency, withdraw to a second exchange an change back to BTC
- use gambling sites with a central hotwallet
- buy freshly mined blocks directly from a pool owner
I would like to see a governement trace you if you used a combination of these 4 methods while always being connected over a different, trusted VPN + a proxy or Tor.
Offcourse, like n691309 already said, each of these methods will cost you some satoshi's and a lot of time...

I don't understand the information on that site. Is that my trust list? It said that I could add people onto the list. I am really confused now.  Pls explain more. Thx There is a default trustlist. People that haven't added/removed/edited the default trustlist are all using the same list to decide who is trustworthy and who is not. However, the list IS customizable on an individual basis. If you customized your list, you'll see red/green trust for different members than the people who use the default trustlist. The default trustlist: Theymos is branch 0. He added the people in depth 1 to his trustlist (for example HostFat). The people that are in depth 2 were added to the trustlist of the members that were in depth 1. The people that are in depth 3 were added to the trustlist of the members that were in depth 2. Since it's your trustlist, you are also in branch 0 of your own trustlist. You could potentially add or remove people from the default trustlist to customize your own list. If you add somebody, he is added to depth 1 of your own trustlist. The people that are in the trustlist of the person you added are added to your customized depth 2. |

Can you guys tell me as to how I can attain positive trust for a Bitcoin account. At the moment I am neutral. Is there any way to get rid of negative trust? And can you have both positive and negative trust? 1. Forum's trust system is not moderated. 2. You will retain your neutral trust unless some user from default trust list will give you positive feedback. 3. So Only Default Trust users will make your trust rating 'go red' or green. 4. Only way to get rid of negative trust is to mediate with the person who left it. 5. You can have something in between, black trust numbers with orange accent, it appears if you receive both positive and negative trust rating from default trust users. Who is part of the default group and how do you get them to give you positive trust? What do you have to do? And is it possible for me to get on the default list? Thx. Here's the DT list: https://bitcointalk.org/index.php?action=trustIn order to get positive trust from somebody on this list, you should always behave well, be honest, be constructive. Sooner or later, a positive trade with somebody from DT will get you in the green, or maybe if you are very constructive, they'll give you a positive feedback for being constructive. To get on DT, somebody who is already on DT has to put you in his/her trustlist. In reality, a lot of people got some positive feedback from a DT member, it's not that hard if you're active, honest and contructive. To get on DT, you have to be handpicked and truly trusted by some of the members on DT, this is something that's really hard to achieve All in all, you shouldn't really worry about your trust-status. It should be something that has grown organic. |

One important point is still missing in this discussion: you should probably not use localbitcoins as a mixer because it wasn't designed to mix coins.
AFAIK (haven't read their whole FAQ), they do not promise not to keep logs, they're public, they're easily identifyable, they're known by the authorities.
In other words: there is no solid guarantee that they will not keep logs, and since they're known by the governement, there is a reasonable chance they would have to hand those logs over whenever law enforcement forces them to.
Bitmixer on the other hand is designed for the sole purpose of mixing coins. In their TOS it is clearly indicated they do not keep logs, they don't have contact information, so there is no door to knock on by law enforcement.
In the end, it's about you... If you just want to sever the bond between your transactions because you kinda like the anonimity, things like localbitcoins or online casino's might be sufficient to mix your coins. If anonimity is your top priority, you might want to start thinking about combining a decent mixing service with a second (and possibly thirth) "trick" to anonimise your coins.

I can write a positive review for you, but only if i actually like the website i'm reviewing... You can PM me the url, and i'll let you know if i can do this task if you're interested (btw, i would prefer it if you'd escrow the funds first)!
