Understand basics like the following:
1. Learn to back up your wallet balance
2. Learn to save your private keys and do not share them
3. Learn bitcoin balance typo errors can be made eg: 0.1 when you meant 0.01
4. Learn bitcoin is a non reversible payment
5. Learn to use reputable escrow with +1 or higher
6. Know in the bitcoin world of business anything can be gone within in instant.
Is backing your btc wallet really necessary? I suppose, it is unnecessary if I just buy/sell. is it right? Yes if you want to keep your bitcoins online without having a wallet on your computer, but I don't know if that is very safe. If the site goes down or is hacked, you could lose control of the bitcoins. : / Online shared wallet are not 100% secure. The operator have full control of your Bitcoins, try using wallets like blockchain.info and enable 2FA. Since they do not have any control over your Bitcoins, you will not lose them if they get hacked or run away. It is pretty much secure from hacker too compared to normal desktop wallets as they need 2FA code to access your account. To be honest, nothing would be 100% secure. Whether you keep a paper wallet in a physical location or an online, or a desktop wallet, there will always be insecurities; it's a wallet, like any other wallet. But I agree with the blockchain.info; it is one of the more reliable ones. The offline paper wallet pretty much eliminates much of the risk, the risk of hacker getting your private key. Risk of bad RNGs can be eliminated by using mouse movement to generate a private key. Encrypting with BIP38 eliminates the risk of a person finding your paper wallet and spending it as they need the password. |

Hey all
I've moved my bitcoin client to another machine and at the same time used the opportunity to upgrade to v0.9.3.0-g40d2041-beta (64-bit)
Wasn't worried about redownloading the blockchain, got decent broadband speeds and never been a problem before.
My wallet backup is safe so started with a fresh install and intend to copy my wallet back over when it's synced.
But for the life in me I cannot get it to sync.
First attempt after 3 days hung at 14 weeks. Client status was "no block source available".
I saw in another thread to add a bunch of addnodes in the debug console, I added about 10.
Left it for a few hours, nothing changed, still stalled.
I tried launching the client with a -reindex, this time it stalled at 27 weeks (been stuck there for 24 hours). Status is still "Synchronizing with network" but it cannot get past block 297402.
I'm not very experienced with configuring the client or more advanced console commands and am at the limit of my know-how. I'm not using VPN or TOR or anything weird.
Any tips and ideas would be really welcome!
Try restarting the client, how much nodes are you connected to? Bitcoin core only allow 8 outgoing connection which means what you did was pretty useless. What is your system specs? Could you do a getpeerinfo command by going to your console at the debug window and post the result here? |

what about cex.io? I've read somewhere on forum that it's good. I've checked out the site and it looks dissent, I didn't register thou.
cex.io offers OVERPRICED and Never-ROI mining contracts. The maintenance fee is 50+% which means they only give you less than half of your profit and take the rest as fees for electricity and datacenter upkeep. Their GHS are way overpriced, 0.002++BTC while other cloud mining contracts offer 1GH at 0.001 with lesser maintenance fees. |

No, cloud mining are significantly more expensive than home mining. They wouldn't be renting their hardware to users if they are actually profitable. Unlike Cex.io, cloudhashing and various other cloudmining companies, they do not have proof that their hardware are actually running. Even if they have proof that their hardware are mining, you won't be making any ROI.

desktop is more secure
A lot people lost their bitcoin from desktop wallet.. one thing that makes me paranoid to put it all in one wallet. any other suggestion? You can create a cold storage wallet and transfer majority of your funds offline (60-90%) and make a desktop wallet with small percentage of coins enough for day use. It should be secure enough as long as you don't download and run softwares that are suspicious. |

So I'm pretty new to BTC and i've been using faucets for satoshi for nearly 1 week. i've only gotten about 50 US cents and I would like something about $50 dollars. Is their any site online where i can mine without downloads? I've tried bitcoin plus but I earn much more from faucets. I know i can't make the amount i want from faucets so is their any alternative? Please help.
Bitcoinplus is a scam. Your best chance is to provide your service at the service section or go to the goods section to sell the goods available only at your country. Signature campaigns are also a good choice but you must post constructively. However, signature campaigns don't allow users to earn a lot, less than 50USD for members and below. |

BTCJam gets big upped a lot lately, but of course, you trust them? i dont.
The risk is huge at BTCjam. The A graded borrowers have the same potential to default as a C. There have been manay cases of such a default. Personally, I have lost quite some money investing there. They don't do anything with their defaulters, which makes it an ideal place for scammers. |

There are plenty of sites which are HYIP or ponzi. Don't even visit sites which claims to offer a high return on your deposits, they are a scam. You can try investing on gambling sites but the risk is huge as whales can wipe out your investments or the site owner run away with your investments.

This much BTC in the stream then why the price isn't getting up. It should rise above 500 given the current market cap. But all this transaction, where are they leading to?
It can just be people withdrawing or transferring coins from one another. Since the address don't give out names or personal information, some of the transactions may just be people moving or withdrawing coins to their wallet or people spamming dust amounts to advertise. |

Dear users,
please be informed that bitcointalk.org owner/owners sell or use or abuse or being hacked or I dont know what ...(users passwords)
My experiences:
I used same password to this nickname and my email address, and as I use gmail, when someone trys to log in to your email from another IP you will get message.
I get such messages like 10 times.
What does this means ? That means that someone knew my password and as I had same password on bitcointalk and gmail only, that means that bitcointalk.org owner/owners sold some passowrds (or all passwords) or abuse them or just being hacked several times.
Very poor for website, which is number one in btc community (by visists) and very poor customer support from owners, who are not able to remove fucking trust system which is abused every day.
I have never experienced such things. You are just making false accusations without any evidence. Not only Theymos know your password, if your computer have malware, the owner of the malware installed on your computer knows about it too. The person trying to log in may just be some script kiddy trying to brute force your email. |

It is hard for normal home miners to even regain half of their money, don't even talk about ROI. Those ASIC miner you saw are outraged and used, they can have a shorter lifespan and lower performance. If you are mining as a hobby, buy a USB miner and use it to mine while learning about Bitcoin. Don't expect those to generate Bitcoins and ROI however. Since that's cheap, it would be useful for educational purposes.

Mining pool's earning depends on how well you code the back and front end having, reliability, trust and fast hardware. Some pools do charge a fee for their service, around 1-3%. If you design the pool well and have stability, you would have high earnings as more people would mine on your pool. Mining pools aren't that easy to manage, you need good customers service, nice looking and smooth UI, fast servers. If anything happens to your pool, you would have to solve them within a short period of time. Successful pools code the whole server themselves instead of getting a ready made back and front end.

I hate to say it but BTC is doomed unless they change their business model.
I agree but Bitcoin core is the network of bitcoin.  If you don't have bitcoin core ... bitcoin doesn't exist.  Pool's and mining station is the fondation of the bitcoin network. They use a bitcoin core (or bitcoinj) completly installed. At this time, you can retrieve more quickly "bootstrap" from torrent official link (need 24h to recreate the blockchain with 75% CPU usage) ... or from other P2P network in final stage (upgraded every 10 generated block in a list of downloads, no need CPU, index and chainstate include). Dev. must implement this strategy to diffuse more quickly, the blockchain for new client of bitcoin core. The developers are developing headers-first synchronization which can make normal computer sync faster. Bitcoin core are normally run by Bitcoin enthusiast and other online Bitcoin services. Bitcoin core can only be useful to the network if you port forward port 8333 and leave your computer online for long periods of time. For normal user, it would be better to run a SPV wallet. |

Dicing is one of the games which have the lowest house edge. You can lower the edge of other games ONLY if you know how to apply the strategy well. After all, it's gambling so you would most likely lose in the long run in any games.

It took me 23 hours to add fully functional bt-core on my MAC. Downloaded bootstrap.dat and synchronised with network. Macbook is new, but process was so slow.
It took me 44 hours to install Armory. I switched to an online wallet Multibit, but it's not 100% anonymous or even as anonymous as Armory. I hate to say it but BTC is doomed unless they change their business model. Armory needs Bitcoin Core to function properly. Sure MultiBit isn't 100% anonymous, you can just get a anonymous VPN or use Tor and it would be as anonymous. Multibit just use their server to check balance and broadcast transactions, your anonymity isn't 100% compromised this way. Running a full node is just for users which are more advanced for example, developers. Normal users are encouraged to use SPV clients. |

I can't even run Bitcoin Core on my desktop anymore due to the speed of my Internet connection. I have my wallet hosted on a VPS.
Your VPS provider have the potential to steal your wallet since they have direct access to your VPS. Why don't you run a lightweight client instead? It is much safer than having your wallet at a wallet which you have no physical access to. |

as the topic says: is there anything called browser mining?! i mean you open a web page in your browser and it starts mining coins for you? the reason i am asking this is because i was searching about altcoins and i came across pandacoin and in its official website there is browser mining! here is the link to take a look: http://pandacoinpnd.org/pandacoin-browser-miner/how does this worK?  Some of them uses WebCL or Java to use your CPU/GPU to mine. They aren't usually as fast as normal desktop miner (CGMINER, BFGMINER). There are some scam sites like bitcoinplus which uses your processing power but don't allow you to withdraw some just install malware on your computer. |

I don't trust mixers, I don't trust VPNs. Do I remain anonymous? Will my IP be traced when sending/receiving BTC?
What happens if I use Armory without TOR?
mixers don't keep records, but if you don't trust them, your bitcoin can be traced to you more easily, even if you hide your IP. Your IP address is not going to be logged unless the government or police are after you. Then they will ask your ISP to track you, or they will install their own backdoor sniffer program without asking. So you must trust somebody or you will be traced. How do you intend to buy BTC? The same trust exists, unless you buy it in person from a stranger in your town. Using Armor without TOR is safer I have heard, than using it with TOR, since TOR has lots of spyware sites in it (the dark network) that will steal your BTC. But I'm a newbie, so ask around. Mixer can keep records, you don't know if they are saying the truth. Your Bitcoins can easily be tracked if you don't use a mixer and a new address for every transaction. Unless you are a criminal, no one is going to waste their time inspecting blockchain for your transactions. To try to gain maximum anonymity, try using time delay feature on bitmixer. There isn't any risk to send Bitcoins by tor, your Bitcoins aren't going to get stolen as it doesn't visit any website, just connecting to nodes and broadcast your transaction. The security risk here is minimal. |
