I don't think we will be using Bitcoin Technology until the quantum computer era starts... Just my personal opinion!
Why? Do you think it will exist/created a new concept better than the actual bitcoin? I think the blockchain will exist for ever, it is an invention like internet and all we know it is extremely difficult to replace the internet protocol. |

i would be happy if it is above 1000$
Everyone will be happy if the price will be more than 1k dollars, it's normal. if people are just waiting 1k to dump asap, then it will never reach 1k, the price can't be raised by poors who just hold and wait for the miracle, wihtout the influence of strong individuals, the price will remain low Interesting reply, but why a rich person should invest in bitcoin? He can open any charts of the last few months and see this: after I think he will not buy not even 1 bitcoin  . |

on sha256 security bit are only 128, and quantum computer can break this(i can't find the article), if today pc can break 64 quantum computer can break at least the double of that
so bitcoin will need an hard fork in the future to survive
Stop talking nonsense. Quantum computers can't break SHA256 (used for hashing) without brute forcing it unless a flaw in it has been found. There is no article to link. I'm not saying that someone won't find a way to attack it in the future though. you are wrong it can break 128 key(the power of quantum computer is like a pc that halve the difficulty, and if today pc, tons of them, could break 64, then a quantum can break 128) this is not enough to break sha256(or the private key which is 256 bit) i know, i didn't explain it well, but it is enough to break the pubblic key which is 128 bit Your English levels are under those of a 5th grader. Consider taking a course, because you complicate things and usually make no sense. I never said that SHA256 for a normal computer wasn't SHA128 for a quantum one. You didn't explain it because it can't be explained well i.e. what you said effectively makes no sense. A quantum computer can't beat SHA 256 (i.e. SHA 128). Actually if SHA gets broken the problem will be on a much larger scale where Bitcoin will be irrelevant (unless globally adopted). A lot of things use SHA, for example banks. What I'm trying to say is: For SHA256, it effectively becomes SHA128 to a Quantum computer. Now the question remains, can a Quantum search for SHA128 faster than a classical computer search through SHA256? With out current technology and for the near future, we still can't build a real Quantum computer that can even begin to tackle this problem, let alone solve it. i think you are not understanding, my english was clear enough in the last post you quoted, quantum computer can break any 128 key, it has been said many times, there is no question here now, public key are 128 bit, instead private key are 256, so the first can be brute forced by any quantum computer, and if you have that key you could retrieve the private key, but this only if the targeted public key is send when you spend a transaction here a link http://bitcoin.stackexchange.com/questions/6062/what-effects-would-a-scalable-quantum-computer-have-on-bitcointhere are many other confirming this Thank you to this link, thanks to it I have found this thread (of Come-from-Beyond) : https://bitcointalk.org/index.php?topic=153302.0Don't want to open the link, here the post:As we all know elliptic curve cryptography is vulnerable to a quantum computer. For a conventional computer difficulty of breaking 256-bit key equals 256/2=128 bits. For a quantum computer it's just sqrt(256)=16 bits.
Bitcoin address is a hashed public key of 256-bit EC. Hashes are resistant to quantum algos, so while someone keeps his public key unknown it's OK. But when he wants to transfer his money he must reveal the key.
Let's assume that an attacker with a quantum computer monitors all transactions. The attacker can pick any key while a transaction awaits to be included into a block. Now imagine that miners choose transactions with higher fees. The attacker can issue other transaction (when he picks the private key) that transfer coins to his address and set a higher fee. Or he could switch his mining rig on and try to find a block himself. With 0.1% of all hashpower he needs only 5 days to solve a block with 50% chance.
Seems Bitcoin is NOT safe. Or am I wrong?
We can assume everything because I didn't still see a valid and functionally quantum computer. |

London used to be a financial hub with many pragmatic players, so catching up with bitcoin seems to be quite natural approach  . London is a very nice city much butter than others in EU (for example Italy, spain and French). Great Britain made an epic mistake about 150 years ago. When the United Kingdom, not Germany, not the United States, was the original home of the automobile’s innovation. This is not well-publicized in Western culture because of the epic failure in the story, and how swiftly the U.K. acted in its own demise. Instead of welcoming the automobile as a technological marvel that’ll not only provide freedom of travel to the masses someday, but also a massive industry they could cultivate domestically, they shunned the automobile. Instead of a technological advancement, British regulators saw the automobile as rolling machines of death to be feared and legislated out of the country altogether through the “Red Flag Laws”, or “Locomotive Acts” of the 19th century. https://www.cryptocoinsnews.com/london-looks-become-future-global-financial-hub-bitcoin/I wish them best, but london and britain in general is very expensive to run business :| I do not know how it is the cost to open a standard companies, but is it more than one in USA? Reminds me well on what I used to learn about management principles. Companies will only survive if they adapt quickly and innovate to stay ahead in competition. Bitcoin is no exception in this case.
Bitcoin in this case it may be the solution to all the IT companies but why not also a solution for a lot of other companies not related with the technology/informatic. |

Supposedly, what had happened was that someone was able to dupe a Linode customer service rep into giving them access to the server's in browser tty shell. That's the story i was given.
Not exactly, allegedy what happened is the hackers hacked the email address lailai625@hotmail.com due to password reuse. This email address was a recovery email address for another account, which IIRC was admin@glados.cc. Once they accessed this account, the hacker then allegedly reset the Linode password and somehow bypassed the 2FA on the linode account. That is exactly what happened with another site Bitcoinica which was hacked 3 times in 2012, same hosting company and all, and Bitcoinica was also owned by an Australian: https://bitcointalk.org/index.php?topic=66979.0in fact TF was even warned not to use this host for this reason many times by many people and ignored all of them. It is very possible that it is a coincidence, but this also could've been planned. There is one small detail that does not make sense however. The part about how th linode 2FA was bypassed was basically skipped over in his explanation, and also the account admin@glados.cc had 2FA enabled too, so I don't know how the account password could be reset without turning off 2FA, and TF never mentioned how that was done either, in fact he never mentioned he had 2FA enabled on this account at all when he in fact did. Hmmm.. thanks for this short version, I will read also the Bitcoinica hack. He also told everyone (at least when I deposited) that all deposits were backup up with assets in AsicMiner and other securities and that if a hacked occurred, he would reimburse those affected.
I think nobody has never received anything backwards, or am I wrong? He had made a few deals with individuals with larger balances where they received a portion of their deposits back, but thats about it. Instead, he kept all the shares of AsicMiner and other securities for himself, instead of reimbursing those that he screwed over. (and with AM going under that is now worthless as well). I think he never will repay back all the affected customers, too much scam due the related bitcoin service (but the fault it is not all of the customers). There was recently a flaw in (I think it was) authy that was patched where someone could enter a certain command into the box where you enter the 2fa code that allowed people to bypass 2fa. I know that the issue affected coinbase. So it is possible that the attacker used the same exploit. See the below article http://sakurity.com/blog/2015/03/15/authy_bypass.html/The fact that the same hosting company was used certainly makes it look like that the hack was staged as it makes it so he was able to give a easy explanation as to what happened. At this point it would really not be possible to prove anything either way because any logs related to the hack would have been deleted/overwritten by now as the hosting was no longer paid for after the hack. So any records are likely gone. I have heard about this exploit, most probable was used to bypass the two factor authentication. |

How do I know if a post is edited or not?
A post it will appear edit only if who wrote that posts will edit it after 10 minutes, if you want to know if a post was edited pass with your mouse cursor over the date (of the post). More info : https://bitcointalk.org/index.php?topic=754939.5 |

By 2025, one bitcoin will be worth exactly 0, as in big fat ZERO.
Nah I do not think it will never be worth zero dollars, until some few people will use it, bitcoin will continue to 'own' his intrinsic value. It will be worth zero when all the miners will shut down their 'hardware machines'. |

How old is TF  He doesn't come off as someone who is school/college aged. He is very likely 16-18 years old, which is why nobody should post his personal information here and those who lost money should contact the police and/or a lawyer. I don't know the complete story, but can I ask you how much bitcoin has lost (due the 'hack' to inputs.io)? |

bro, I also want to join the Bit-x avatar and Personal message campaign. Plz tell me if i am eligible for this campaign or not. I am a regular poster of this forum. Also I agree with 0.05BTC/ month .
You have a negative trust and he is not taking people with negative trust. Pay 15$ to irfan_pak10 first and then again apply for this  Or if you want you can get an avatar for free like me. He does not have any negative trust :  irfan_pak10 should open a scam accusation against him in the properly forum section. |

We are the gods of life and death now,
I am not telling you to pray God or something but just asking a question: If you think humans are gods of life and death, can you predict an exact time of a death or birth? Please guy, can we stay on topic? However thanks for your opinion but keep off the religion question of this thread . I want to discuss about the political side/view. United Nations serve the needs of a few countries only.It's useless.
This is obvious, if they want to help Palestine who can stop them? The problem is they don't want "at all" help the Palestinian people. |

A theory, and what will happen if some users will start to sell "invites" of bitcointalk.org? This is why we don't need an invite for register, it's free and it will be free for ever. If you have received a valid reply from someone I suggest you to lock this thread, thanks.

I think the quantum computer (if it will be created) can really resolve-crack the sha 128 bit easily but I don't know if it can crack the sha256. |

Nice to see Bitcoin gets taken serious instead of countries and companies trying to prevent people from using it.
I hope they put their plans to action and not end up in just being a plan. With the right people on board it must work out well.
It seems bitcoin is not only an alternative, but maybe it will be a valid option to replace FIAT value. It is almost impossible to regulate bitcoin but I am not an expert of politic and laws. |

what i think? bitcoin will start to rise when we approch the fee era, until then we should forget about 10k-100k, all those price are too far away, the chance that we get there are very slim...
in 10 years it could achieve 1k-3k range at best case scenario
If bitcoin is less than 5k in 10 years, pretty much that means it failed. At least in the sense of failing to get mainstream adoption, and that it will probably never get mainstream adoption. It may still survive for a niche group, but would never go to the moon. Yes of course, but if the bitcoin will go mainstream doesn't mean that the price will be 5'000 dollars per bitcoin or maybe I didn't understand what you meant. It's pure speculation. But - assuming that Bitcoin doesn't fail and is worth zero - a target of $5000 seems to be very low, because you have to consider inflation. Even without hyperinflation $5000 in 2025 will have the buying power of $2000-3000 today.
My prediction: One Bitcoin in 2025 = between 10 to 100 ounces of gold. Because for Bitcoin to survive that long, it will have to grow substantially.
ya.ya.yo!
The halving is the unique possibility of the increase of price. |

It was not necessary the PM, negative trust removed but I suggest all you guys to pay attention when you are "playing" in that site and maybe better stop to using it.
thanks a lot No problem but now I think you should conquiste again the honesty of your old and probable new users, through a promotion or something like that. This inconvenience may be bring to a lose of confidence by the 'players'. |

In a shocking announcement made on April 14, online Bitcoin marketplace Brawker revealed that the company’s growth has been below expectations, which is the prime motivation for the complete closure of services. “Our growth rate did not meet our expectations, and the service does not scale as we would have expected to. The Bitcoin community came up with many great startups and the environment is very different from what it was 18 months ago, when we started working on this project.” ... The unfortunate development came just a couple of weeks after the CEO of Brawker Cyril Houri left the company in a management shakeup. The marketplace was being managed by the developers. The Brawker team has better plans for the Bitcoin community. The company remains confident of the digital currency and will now focus on other projects and create something even more useful in the rapidly changing Bitcoin landscape.

what was the big thing coming for bitcoin? afaik there is nothing but the price drop?
We have already said, it was his personal big news and of course it will not affect the bitcoin price. We can say it was only a "joke" and we don't know if the price will raise or not in these days. Just found this https://bitcointalk.org/index.php?topic=1025782.0Its interesting and it will be good to have something without trolls and sockepuppets  Thanks I have already read the thread, it was related with the tax day in the usa. I think it will not affect the bitcoin price because it is not 'related' with bitcoin and of course the price will not pump or dump (due that thing). |

Yes, I think in the next 10-15 years the technology will grow (that's normal) and maybe the will break the sha 256 bit but first you should remember also the banks use this algo, and I think someone will be interested in the bank (for first) and after all the other things (money related) that are using sha 256 bit.
So at the end I am not worried, if an hypothetical quantum computer will he created, the first target will be the banks.
