Hi all,
There is a very simple question in my head about Bitcoin. I will be glad if someone can answer this.
Its about the Bitcoin address. It is stated that :
A Bitcoin address is similar to a physical address or an email. It is the only information you need to provide for someone to pay you with Bitcoin. An important difference, however, is that each address should only be used for a single transaction.
If each address can only be used for a single transaction how does one can receive more than one payments to his address.
Lets say I have a blog and I want to receive bitcoin donations to the address that I specified. Do I have to update the 30character code everytime that I receive a payment?
How does this work? Can somebody please explain.
Cheers
Bitcoin addresses are disposable, but You can use them forever if You want. If you are using a paperwallet, remember that if you spend money from that address, I will loose a bit of security. All addresses are secured by SHA256, RIPEMD-160 and ECDSA, once you make the first transaction, you broadcast your public key which leaves you with ECDSA to secure your wallet. True that quantum computer could break ECDSA but it wouldn't be the first target. If you look at some wallets for example onchain dice, they always reuse address and never get hacked. The other security concern is weak RNG which could be exploited once you make a transaction. |

I had this suggestion yesterday. The main problem is due to campaigns which pay based on post count as it is too tempting to post to increase income. If the forum sets up rules which doesn't allow this then spam will reduce significantly.
I think there should be a sub board for signature campaigns, and they will follow strict rules like they can only ask for a maximum of, say, 20 posts/month and they can't provide bonus or preferential treatment based on post count. The campaign managers would be made accountable if they fail to enforce the rules.
I think your suggestion is not valid, if someone want to wear a sig. ad it is his peronal choice. The point is he must not spam here in the forum, and as you see in these days the admin/global mod have banned a lot of spammers. Spammers are hard to control. There are lots of campaign paying per post right now and people would be much more tempted to make lots of posts to gets the coins even if they didn't want to spam. If its a flat posting rate, people would definitely just hit the limit and slow down or stop posting as you won't get paid any further. |

Simple question What is the best/fastest way to lev up starting as a newbie member. Please give tips. THX  there is no fast way,you just have to wait! 1activity per day!! maximum 14activity per 2 weeks so you need lots and lots of days to level it up! Wrong, if you have 260post and have 238 post, when the new activity period come, you only need to post once to get all of the 14 activity added. If you post once during every 2 weeks period for 3 weeks, you can post 42 post and the activity will be increased by 42. |

Bandwidth, well, I guess it depends on your location, but generally all these cable and DSL providers are all about downstream and give jack shit for upstream, at least in the US.
It's the same in the EU and I think probably in the rest of the world too. I think they do this to prevent you from running a server from home for cheap. Nope. I do not know what you consider at a low speed, but here ,in Russia, I pay 450 rubles($7.44 or 6.87)(per month) for 50 Mbit/s upstream and 50 Mbit/s downstream. Good to know then! Thanks for the info. In countries I have lived so far the upload was always a 10th of the download speed. That's bad, in Singapore, upload was always higher than download no matter how I test it and the speed is always at or above the promised speed by my ISP(300mbps) |

I Am 100% that China Will Control Take More than 80% of BTC Mining Before 2020.
This is true but it will probably happen sooner than later, have not been around for awhile is there a ban still in china? Yes, but I doubt mining operations will be banned though. Bitcoin is banned, not the mining operations. Bitcoin is restricted. Transactions can still be made with Bitcoin between people but banks are not allowed to handle transactions associated with Bitcoin. Maybe that will allow them to mine bitcoins but won't allow them to dump into the exchanges. Kind of good then How can a bank prove a transaction is bitcoin associated lol. If I sold bitcoins on Localbitcoins, for example, and someone did a cash deposit the bank cannot find out what the transaction was for? On what premise can they conclude it was related to bitcoin. Bitcoins(just like WoW gold etc) are useless to the Chinese, the USD is all they care about. Basically, most exchanges uses a static bank account. The bank can know that the bank account is used for Bitcoin trading if they check it via the website. It isn't difficult to bind an account to a Bitcoin transaction. |

I believe that each bitcoin core installation should include a prompt to backup the wallet on external media (CD, thumbdrive/USBstick, memory card, etc) with the option to encrypt with passphrase. This will assist users who are not tech savvy to at least have a protected hard copy elsewhere.
I think you meant soft copy, hard copy is usually something printed on paper and is not inside any electronic devices. Also, there is a risk of the device getting corrupted. |

I recommend you join LuckyBit full member 0.075 / month at least 50 posts.
if you post a lot, you can join bit-x which is paid by post.
Luckybit have a strict posting and post history requirements. You have to past their checks to be enrolled. This is rather strict for 0.075 a month. Furthermore, OP is not yet a full member until 2 or 3 more activity increase. |

... This is the first time I have seen blockchain.info showing separate stats for BW.COM at their mining stats page. https://blockchain.info/poolsThe top four miners (percentage of recent block wins / hashing power): AntPool: 20% F2Pool: 16% BW.COM: 11% BTCChina Pool: 7% Total China: 54%(Sort of reminds when GHash.IO briefly took 51% of mining) Does antpool operate in China as well? I never knew that. Wow, so was the price drop caused by the Chinese miners dumping their coins? Bitmain is based in China so their pool are also based in China. Perhaps, but since they aren't private and solo pool, you shouldn't assume they are all from China. The dump can happen for a variety of reasons. Many Chinese miners sells a portion of the coins and hold the rest. (judging by what the biggest mining farm's owner said) |

I'm a consumer. I want to know how to buy it, how to buy stuff WITH it, and how to keep my coins safe.
I have a blockchain.info wallet with bitcoin deposited. I have a strong password on this account and I use 2 factor authenticfication, in this case Google Authenticator, this keeps my Bitcoin safe as they can be online. I have the blockchain app on my phone. This is locked with a code, as is my phone. When I want to buy something with bitcoin, I open the app and scan the 2D barcode. It then confirms the amount that will be deposited on my phone, I click accept, and I have bought something using Bitcoin. I have done this to buy Pizza online, Coffee in a cafe and a meal in a Bar in the last month. All worked perfectly and quickly, were secure and I would happily do again. The main thing for security is that you have 2FA, a strong password, you never show your private key to anyone, keep your antiviruses and firewall upto date and don't click on any dodgy links related to bitcoin or the bitcoin forum. Trust is needed for most online wallets whether or not you control the key. Multiple incidents has happened on blockchain.info, once is the reusing of 'k' value which allowed hackers to bruteforce the private key easily. Even though they say it is opensourced, they do not need your approval before adding a new feature or updates which may open new vulnerability. |

Doesn't seem like a good idea. Some people do have a shared IP that is shared among users. If two Bitcointalk users uses it frequently, they may be mistakenly banned. This would happen with dynamic IPs too. Signature campaigns won't bother with the number of accounts you own as long as you post constructively. Multiaccounts can also be detected by traces of spendlinking in the address and posting in a similar style .Most signature campaigners would want their signature to receive the maximum exposure possible.

I am not surprised that this is true .
But doesn't it create a vast imbalance of Bitcoins in the world due to this ?
I dont believe it would affect the imbalance of the amount of Bitcoin in the world. Most people withdraw it after mining and they may be from other parts of the world. The imbalance of Bitcoins would not affect anything IMO as Bitcoin can be used anywhere with internet. |

cpu mining is outdated by a long shoot, the same for gpu, and asic are not profitable too
It's all about the factors affecting the profitability, electrical rates, payouts and hardware cost. If the cost are low, chance ROI and profitability can be high. However, it is a gamble. The price and the difficulty is pretty volatile, you might lose your chance of ROI due to increased electrical rate or difficulty. |

Most mining software nowadays disables CPU mining by default due to its inefficiency.
Some pools offer port 80 or 443 as a mining port. Eg. Bitminter.
I have tried using VMWare before and it has an option to limit CPU usage. It can be possible to do so but your performance would be heavily compromised.
Even with a thousand PC, you would still have little hashrate and use lots of electricity. Buying a single ASIC would probably outperform all of them at a lower price and lower electrical usage.
All mining softwares allow you to minimize it and you can do other things while mining.
Note that if you are using a shared server, you would probably be banned for using too much CPU resources and they will not refund you.

I'm thinking of setting up an e-commerce store selling books for bitcoins, but waiting for the six confirmations to minimize my risk of a double spend attack. Does anyone know of any charts out there that list average confirmation time for the six confirmations to occur? My wish list for these charts: two charts, one that shows average amount of time to get six confirmations without any transaction fee, and another to show average amount of time with a transaction fee.
My concern is that I'm okay with waiting a day or two for the confirmations, but with typical e-commerce being instantaneous, customers would likely be frustrated and leave and I'd get no sales if this is common.
6 confirmations in the long run would slightly take less than 1hour. However, bitpay does offer no confirmation transaction. It is still done on chain but if the transaction has been propagated well and the network has no competing transaction, it would be pretty safe to be secure against most doublespending attacks. |

You would have to use tails as a USB Os that means that you install tails on an usb then boot it up, it will run persistent thst means you'll files will be saved on the usb. You'll be able to use TOR and electrum 2.0 directly from your tails usb and electrum allows the use of change address or generating massive address to receive your bitcoins. Google on YouTube how to install tails on a usb.
You'll need to read about Linux so you can understand how does it work.
tails is a live operating system. You don't install it -1 Like Reynaldo said : load it, create a permanent volume (portable hd, usb stick, fat sd) install bitcoin-qt Linux wait for sync, use another usb-sd-what ever for wallet.dat (or one storage for both) and rules. another cool variation is a btc node on tail and then use connect command from another computer. better usage model? USB sticks and SD cards has limited read and write cycles depending on your product quality. Not everyone has a portable HD lying around too which would require you to spend some money to buy one. Syncing a Bitcoin core on a usb stick or SD card would also be a hassle due to space constraints and IO speed. If possible just install the OS on the computer itself. |

A new report from security firm Symantec claims the number of Trojan malware programs targeting bitcoin users has fallen in the past year. they suggest that since the number of users of crypto is still low it is not a good target! it is a good news but i thought cryptocurrency was getting popular so as a result it will attract evil people too but seems not! source: http://www.coindesk.com/symantec-bitcoin-financial-trojans/If u use multisig, trojan cant do anything as one private key wont give them the bitcoin... Some users are plain lazy and just sign them all on one. Also, it is possible for malware to spread via a usb storage device. If this happens, the other keys could probably be compromised. Having lower number of malware programs doesn't mean anything. I bet there are still users losing their coins either due to carelessness, ignorance or for whatever reasons and most of the time it sounds easier than it seems. And there were cases of coins getting stolen having nothing to do with malware, it was just left over there for the taking.
probably we blame too much to the bitcoin users who hasn't implemented security method to protect their bitcoin and end up losing them! It may be the reasons the masses still stay far away from bitçoin. Bitcoin itself needs to be unbreakable like the banks vaults and user friendly. The masses will be comfortable to use it. Since Bitcoin is decentralized, we can't expect someone to take control of your coins and keep it secure for you. It's your coins and you need to take responsibility for it. Malware threat can possibly never be eliminated in our real life world. The best way is to practice security measures. It is very easy for one to reduce the risk of being infected with virus on an everyday computer :"Don't download foreign programs". |

Zero surprise there, as most of tech and profit harvesting industry is there, giving others small chances of making positive returns.
They are mostly not interested in bitcoin itself, but only on profit they can make mining it, but doing so it happened that they spread some awareness about bitcoin on their comunity
that quickly produced exchanges and other bitcoin related industry that makes them even more profit.
cheers
There are still a percentage of people preferring a pool based in China than one outside of it. Since IP address are not revealed to the public, we don't know how many percent of the miners in the pool are based in China. Blockchain.info's hashrate chart isn't the accurate.They base it on the average of a timeframe specified and calculate according to the amount of blocks found. If the biggest pool experience a very bad luck, it is possible that the hashrate share would be lower. There are plenty of cheap warehouses and electricity in China too. With alot of ASIC manufacturer based in China, they can buy it in bulk without experiencing huge shipping delays. |

Not only trojan but silent miners! That makes 99x PROFIT! Satoshi wont be happy with that  If satoshi's computer got infected...its over...hacker will probably take over Bitcoin  Silent miners do not profit as much as before. To gain a viable hashrate, you need thousands of the most powerful and biggest hardware. GPU or CPU mining is dead long ago compared to ASIC. |
