An important difference, however, is that each address should only be used for a single transaction.
Actually this is only helpful for bigger security and anonymity (if you do a lot of transactions), it's not a must. Indeed, I heard about the possibility of exploits exactly for the case the same wallet is used many times. I also use Multibit and never had issues. Just make sure: you save (print?) your public and private key somewhere (very) safe. -or- you save your .wallet file somewhere (very) safe. A lot of people seem to forget to do this and cry half a year later when they cleanup, format or upgrade their computer. The security part is pretty wrong. There is no advantages of reusing addresses for security, it is more for privacy. Also, I assume you are talking about the possibility of quantum computers breaking Bitcoin's ecdsa but it would be useless as the SHA256 would still be secure. Even if it is developed, we can still fork to another algorithm. There are other better things to do than to attack Bitcoins when quantum computers are built. |

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
The key word here is 'should' it isn't necessary to change BTC address after receiving transactions. It is mainly used for promoting anonymity. A bitcoin address can be resused as much as you want if you have the corresponding private key. |

At least 3 confirmations to avoid double spending
many exchange will be credited after 3 confirmations on the Bitcoin network.
One confirmation would typically stop any double spending. However, doublespending cannot be avoided unless it has a lot of confirmations. More blocks just reduces the risk of double spending. |

It would be the best if you could purchase from a local BTC ATM or localbitcoins.com it will always be smooth.

The idea is that the transaction fees will replace the block subsidy.
what if the price at that time is just $500 for example. pools will only lose money if tx fees won't get an upgrade. how many pools will keep their miners run then? The ASICs should be much more efficient and electricity would be much cheaper at that time. This shouldn't be much of a problem. There are still miners who would keep their ASICs running just solely to support the network and not for profit. |

Wow! correct me here my total posts are 555 , excluded 255 but final posts as 543 though final payment is 0.36 i.e. excluded 255 posts Can i know why ? you can check my post history , i might have some short posts but they aren't troll or useless And even if we remove them , there aren't that many  you are in top ten posters buddy you will get extra 0.1 btc also  It's quite impressive to post that much per month, even in a short month tho this person is definitely worthy of the .1 bonus. Not hard to see that 20+ posts per day would require a % of ones that don't mount up to the bots acceptance levels. I've always thought koelen3 as a top poster tho from what I've seen. This person has great insight, great points and likely drive positive attention towards Bit-X. No he is not in top ten. He is at 11 th position. Sad If you look at my posts count as 543 , am at number 4 Though if he reduces them by 255 which is totally unfair , am at 21st position not 11th I don't understand how can they be 255 If you are thinking of bonus with post count it is nit possible it will depend upon quality of posts with count post . Am not looking for bonus , am just saying why were so many of my posts excluded , even his own excluded posts are 184 which are due to because he post here , i only posted in bitcoin discussion and begginer's and help and a little in marketplace why shall they be excluded Perhaps he didn't find your post constructive enough. Just to find a few, https://bitcointalk.org/index.php?topic=970245.msg10597771#msg10597771https://bitcointalk.org/index.php?topic=945718.msg10580682#msg10580682https://bitcointalk.org/index.php?topic=959774.msg10580619#msg10580619https://bitcointalk.org/index.php?topic=945715.msg10580581#msg10580581https://bitcointalk.org/index.php?topic=956674.msg10580569#msg10580569Those post weren't extremely constructive and I just roughly looked through it. |

I don't get it why there are 2 kinds of ads? Why Stunna is paying for this Singapore ad? It is an anti ad!
What do you mean? When I saw the ad and read it I actually thought it was trying to be negative against PD though. There are more existing places to visit ie other Dice sites  . I think a signature campaign is probably more effect than forum ads. Stunna should put that mooney into a smaller signature campaign or something. Anyone can disable the ability to view ones signature. However, most people cannot block these ads as they are resistant to adblocks, only VIP Hero/legendary member and moderator/admins can disable the viewing of ads. This is more effective definitely. |

As long as demand is present, there is no way that bitcoin will fail. And also, if the miners shut down their miners at the same moment, transactions cannot be processed, and thus disabling the network as a whole.
That's what even I was thinking, that if all of a sudden, all the miners shutdown their miners and the txns stop processing, won't it be considered as failure to the whole BTC network as what will make it run if the difficulty suddenly decreases and (not at all possible but) reaches to 0? How will the Blockchain work? Is there any backup by the Foundation? Well, I definitely know one miner who won't shut down operations. Number of miners coming down will increase the chances of a 51% attack, but definitely won't mean the end of Bitcoin. Even if one miners don't shutdown, if 50% of the network shuts down, a 51% is more likely and transactions would process slowly as the difficulty is too high. Also, difficulty change would take lots of time since difficulty changes every 2016 blocks. You mean it ain't going to reflect to anything related to BTC if the mining gets shutdown? Blocks will be slower till 2016 blocks later when the difficulty is adjusted appropriately. I highly doubt 50% of the network would shutdown. Someone is bound to keep on mining to contribute to the network. |

I believe the op didnt mean what if we now exploit and use up all addresses, but rather in future, since we all imagine that bitcoin will still exist then.
With advancement of technology, i ackgnowledge the scenario where it is possible for some advanced computing to create this problem.
But what u fail to realise is that bitcoin will also advance, and will walk around any issue we may have, and for now its impossible for that to be a problem
cheers
No advnced computers can bring up such a problem as of now Read what i wrote before commenting please. I did not say that there can be problems with this issue now. I said that in the future (you you know how fast computer industry is evolving?) its quite possible that some issues like this may come to light. Ofc, bitcoin will adapt and counter anything that prooves itself to be a problem, nothing is hard-coded. (xcept 21 mill coins limit) cheers Based on the Moore's law, computer's speed will not double anymore after at most 2020 which it would then grow at a slower rate. I don't see this happening in the future since it would require a lot of power and cooling if such a machine is built. You can change anything in the protocol if you do a fork but that would require everyone in the network to switch to the version you created. You can technically change the 21million BTC limit or anything else but the whole network needs to agree or a fork will happen. |

 Is this real? PD was banned in Singapore ? Yes. This is the read PD. Its banned in Singapore(as the ad says) and AFAIK its blocked in Australia too. They are just gaining attention by advertising their site that way. Must say those are awesome ads. yup, countries are starting to ban online gambling sites. thats kinda bs why they ban them if bitcoins are not real money? What do u mean "bitcoin are not real money" ? Can u buy stuff with it ? - Yes u can. So it is real money. Fiat money is nothing more real than bitcoin , quite the opposite, we don't know how much fake , non existing, electronic fiat is out there , while with bitcoin we do know exact figures and we can see them on blockchain so it is much more real than fiat that banks use for example . I guess he meant to say that bitcoin is not seen as real money by "governments" officially. But practically they also know that its equivalent to real money and so its banned. Well yeah. But i think reason behind this ban is more of a economical nature, they want to keep theirs money in Singapore. We had similar situation in Serbia, our national lottery made poker room , and government made law that we cant gamble on any gambling site outside of Serbia  . It was rly hard to get money in and out foreign gambling sites like fulltilt , pokerstars ... I guess the main problem Singapore is trying to resolve is the problem of online gambling and family issues. This is how it looks like when I attempt to load primedice:  . It isn't effective since it can be bypassed using VPNs or Tor. Just-dice however, is not blocked. Maybe PD has more recognition here. was just pondering that is there any way for the government to ban a site by which its users cannot access it through tor? Also JD got closed for some time and it lost its players to other gambling sites. It doesn't accept bitcoin now and so has less recognition. It still has an effect like for the players don't know how to use or never heard about Tor or VPNs wont be able to access it, not all of us are that tech oriented. Singapore is pretty tech savvy. A simple Google would give them the answer to bypass this restriction. They are pretty strict with gambling online since its easy for people to get addicted. Not only primedice is blocked, more than a hundred of them are blocked. |

Only ur usb graphics burns and dies out . There nothing to mine with it .
Use ASIC for them. If you use a fan and a heatsink attached to it, it would have a longer lifespan. But if you can't afford to buy a expensive cutting edge ASIC, you probably shouldn't mine. what if he just wants to help out the network yo ? who cares bout the money when you can join a revelution. Having a GPU or small USB ASIC to mine would be a relatively bad choice. The network hashrate is very high, the impact would be pretty minimal as the GPU/USB ASIC's hashrate is extremely low. |
