Thanks for the replies. I looked at Eligius and it flagged my Anti-Virus as a malicious website. Ghash came up fine, so I think i'll use it. Their website looks much better than Slush's pool. Thanks for the info, I'll close this thread.
It is probably a false positive, eligus is operated by a trusted person of this community. Ghash.io actually had some issues last time I used it and had to switch to eligus. And antminer s3 are not easy to have ROI, think twice before buying. |

The pool you should choose is one with low fees, trusted, have the most reliability and uptime. If two pools have the same fees and uptime with a different hashrate, in the long run, both of them will have the same earnings, hashrate only affects your frequency of payments. I would recommend eligus as it is reputable and have 0 fees and good uptime.

Safest wallet is definitely a hardware wallet which is opensourced and secure from virus attacks, for example, trezor. The disadvantage is that it is very expensive, $100 per. For normal uses, a paper wallet/offline raspberry pi would be secure enough if you sign transactions offline.

[LINK REMOVED] for the people who use this it's updated now  and for the people who think it's a virus fuck off! Open source it then. It is impossible to break the sha512 hash even with powerful hardware. Why would Primedice still be using this if it can get cracked then. |

How about an Banana Pi as full node? It costs nearly the same as RPI but has 1GB of Ram (which should be sufficient,right) and a SATA Port. In March I will try to get a full node running on Banana Pi with 10Mbit upload. Will there be a significant benefit for using an old SSD for Blockchain storage instead of oldschool HDD? Maybe I/O performance? Another cool Project: Bitcoin full node using Intel Edison! https://bitcointalk.org/index.php?topic=809090.msg9064556#newSSD would use less power and be more resistant to damage than old HDD. They are also much faster than HDD and is useful for syncing and relaying of blocks. |

Thanks for the sites! My fear is just that the private key doesn't work anymore after encrypting it (or I lose the password for the BIP encryption). It shouldn't be possible that it won't work since private key won't change. You still have the original unencrypted private key in your computer if you generated it there though. Either recite the password a few times during the day or write down the password and store them in a few secure places. |

What is the cheapest way to run a full node. I do have a few external HDDs and rasp pi laying around.
No unused laptops though.
Suggestions ? ideas ?
You'll have difficulty running a full node on a pi. It doesn't have enough ram and will end up using swap. You can use swap and also take steps to reduce memory usage but you would need to have a hard disk/SSD connected to the pi. AFAIK, SD cards aren't designed to have a heavy read and write cycles and can be relatively slow. |

I am interested in creating my own dice/gambling site (like Primedice and Just-Dice) and my own altcoin exchange (like Cryptsy and Poloniex). Does anyone know how passive such sites are? For example, writing a novel is passive income because once you write it and find a publisher, you don't need to do any work for the money to keep rolling in. Another type of passive income is a rental property - especially if you have a property manager, and automated trading where you write the trading bot and it does all the trading for you. Most large businesses also generate passive income for their owners.
So how passive is a dice site/altcoin exchange? Could I write a site using PHP and Javascript, announce it here on the forums, and then leave it alone and still get money? Since it would all be automated and the site will automatically skim the profits from the house edge or trading fees, am I correct in assuming that I won't need to do anything further other than maybe check to see how it's going every once in a while?
If you are looking to create the website and leave it alone and try to profit, I advice you not to bother doing so. Successful dice sites like just-dice, primedice, etc and exchanges do not simply create the sites and leave it alone. They have to constantly listen to he community's feedback and improve on it. You also need to regularly test out your site for vulnerabilities and provide support for your user. Thats the reason why Stunna has a development team and quit his job to manage the dice site. Dice sites mostly generate 1% of the total wagered amount in the LONG run, sometimes, you may have positive or negative profits but in the long run, it usually evens out to 1% profit. |

do not buy cloud mining unless brand is reputable (ie has proven to ship, own and run mining hardware)
This is only part of the equation as their are many other reasons to avoid cloud mining: 1) Increases centralization which is bad for the bitcoin ecosystem vs buying asic hardware yourself 2) Rates often are unprofitable - Use a decent calculator https://bitcoinwisdom.com/bitcoin/calculator and enter in an expected average difficulty 5-20% to see if ROI Please check here as a starting point for research into credibility of cloud mining. https://bitcointalk.org/index.php?topic=878387.msg9697654#msg9697654Companies that aren't labeled as ponzis can still be scams as well , but this is the minimum bar one must look at as a starting point. 1) how does it increase centralization ? Last time i checked (will vary on exact service model provided, but still) cloudmining doesnt attribute new mining, rather transfer ownership of existing hashrates. Depending on exact terms of service, theoretically users can aid DEcentralization by selecting alternative pools 2) yes. and no. far too many, far too volatile factors will shape the final return. Whilst obviously everyone wants to make money, the ROI is near impossible to accurately predict. I'd say cloudmining shouldnt be seen as a sure-fire way to make money,rather it should be seen as a way to try out mining without taking on the risk of spending > $2k on mining hardware then have to have all the associated headaches (cooling, storage, noise, maintenance delays etc). You can switch on / switch off your cloudmining at any point, and see daily BTC returns (even if miserly) and at worst, youre risking 10-15 bucks to learn first hand. On the other hand if you make a paltry 5mBtc per day for a year and Bitcoin raises by 30-40% you could see a significant ROI. basically its low-entry, low-risk mining - users can try it, hate / love it, continue / dump it without ending up with the world's most expensive heater in the garage i agree its a complex process, but i cant see how it hinders the BTC ecosystem or how anyone can say with confidence what their ROI will be 1) You cannot choose a specific pool to mine on. Most pool (if not all) calculate payout based on the selected pool's 24 hour payout stats and still mining at their own pool, if they offer this feature. Transferring of shares means the payout is going to you. The hardware is still mining and the hashpower is under the cloudhashing owner's control. They can do whatever they want with it. 2)Cloudmining will never ROI, you wouldnt get more BTC out of cloudmining than buying the BTC directly. If Bitcoin rises that much, you may ROI but chances are, you would get more profit if you bought and hold the BTC in the first place. |

Hello bitcoin sages,
Could you please tell me: Is there a way to store bitcoin on a laptop/ usb drive / mobile without needing a lot of HDD / SD card space ?
I need a wallet / solution file that would not take up space, yet be accessible at (a fairly) short notice
Much love
Then you should avoid BitcoinQT (core wallet) and try MultiBit (multibit.org). It takes only a few seconds to sync and use. Why ? Does BitcoinQT require to DL the blockchain ? Yes, BitcoinQT downloads the whole blockchain data, which is usually several GB. MultiBit is a 'lite' client which downloads most recent block info, but is equally good & secure for most users. Incorrect, Multibit is a SPV client which downloads the header of every block. SPV clients trust miners to enforce the network rules, full-chain client does not trust miner this way. Bitcoin Core is currently near 27 GB, headers-first synchronization should cut down the initial sync time in the next stable release (v0.10). |

Is your IP static or dynamic? If its dynamic, the previous person who had this IP was probably sending malicious traffic to google. Or, perhaps you have been infected by a malware and it is sending out automated queries to google. Are you experiencing problem searching other terms?

Cloudmining used to be very profitable when the btc price was 600$ or more.
Now Btc price ~300-320$, Cloudmining services having hard time... Probably most of the site owners even cant profit anymore.
cex.io profits because they have a huge maintenance costs. Cloud mining services that are small and smart can still profit because they keep the costs very low. I think like rano said, being small is more hard to survive, unless they have big amounts of gears. It would probably become expensive for them. If you are small you have lower costs, it could just be a handful of people with no salaries or taxes to pay and a very small rent The small rent part is incorrect. You have to rent a space at a datacenter which would not be cheap, considering the power usage. I doubt much people would be willing to be there manage the ASICs with no salary. Also, website design, ddos protection and hosting is not cheap. |

Yes im new to mining as well, and was doing some research on cloud miners. On the site it looks very profitable, but like what was posted above some sites stopped taking new clients or just disappeared meaning there is no way to contact them, or the site has errors in certain places. I want to really test it out to see how it works, but im really interested in building my own cloud mining service as well. I just need to see how it works.
Cloudmining should NOT be profitable. You are either having calculation errors or the site is trying to scam you. If cloudmining is profitable, why would they rent it to people to make a profit? Creating a legit cloudmining service requires alot and alot of funds. You would have to get alot of ASICs, have money for datacenter rent since you cant run it at home. It isnt easy managing hundreds or thousands of mining hardware. |

https://i.imgur.com/TP1XE4N.pngTried sending ~$300 of BTC to my qt wallet, but as I was waiting for the blockchain to download, I encountered this message. I have plenty of physical space on my computer, and can't seem to figure out the issue. Any help would be greatly appreciated. What version are you running? Windows version? Memory etc? How much disk space remaining does it show? :-) Windows 7 Home Premium Wallet: 4.7.4 RAM: 4 GB HD: 199 GB free of 282 GB That wallet version is very old, upgrade it. First, copy your wallet.dat from %appdata%/Bitcoin to a secure place. Download Bitcoin core and run the installer. The bitcoin blockchain will be reindexed and you must wait till it is fully sync to see your balance. Alternatively, you can import your wallet.dat to blockchain.info and you can use it instantly. |

Has the security issue been resolved yet for Blockchain.info? There was a bug that let others control your private keys and people were using their coins to hackers. Yes, it was resolved hours after it was discovered. It was basically a bug which caused the private keys to reuse a value to generate a private key repeatedly. It only affected those private keys generated within blockchain.info during that time, to be more accurate. |

I don't think there is any bank that provides fix amount of interest on btc. One thing that you can do is that you can provide a long term loan on this forum or on btcjam.
Unless you want to lose money, do not loan to people on BTCJam. The identity can be faked and they would do nothing to chase the debt except giving you a useless abritation document. I have lost lots of BTC by investing there. |

I'd recommend Bitcoin-Qt.  It would help bitcoin in general since you'd be running a node on the network. But you'd have to sync with the blockchain, which takes a lot of patience and memory. I think it's around 21 GB now? You might not be helping the network. You need to first port forward the router to 8333 TCP before you can be a full node. The network needs stable nodes with high uptime than a household one which has a lower uptime and stability. The blockchain is currently at 26GB. In this post there are 2 things holding bitcoin back  26GB  Technical jargon.. What the hel is 8333 TCP port.. Port can be opened by googling your router model, theres plenty of places teaching people how to do that. The main drawback is the synchronization time and the space, in the next release, headersfirst synchronization would make synchronization faster. Blockchain pruning in the future will also reduce the size. |
