People are so stupid, bitcoin is the primary currency of most darkmarkets, that is, a multi-billion dollar industry. It may go lower than 300 at some point but it is not going to die overnight or in the near future. Only when these darkmarkets transition to a superior more anonymous currency/platform we will see the true end of bitcoin.
This is true, its not like overnight Bitcoin's technology broke or stopped functioning. In fact yesterday I read Gavins report on how we can scale the Bitcoin Protocol to scale with the volume of transactions = Visa https://bitcoinfoundation.org/2014/10/a-scalability-roadmap/Very interesting read on a few improvements coming to Bitcoin in the next few releases. Additionally I recall reading that the Bitcoin Foundation is going to standardize on a symbol for Bitcoin in 2015: http://www.coindesk.com/bitcoin-foundation-standardise-bitcoin-symbol-code-next-year/With these changes, and all the VC Capitol that is going into Bitcoin related Technology I see this being "one" of the best investments people can make right now. Compared to last year where before the ATH (All time High) to 1000 we have alot more investors in the market this time around. Can't wait for the next bubble peak, see you all their. Edit: Also Bitpay Bitcoin Bowl will be on TV in ~2/3 months - Someone said 12/26/2014 - I hope they accompany the bowl with a few commercials about Bitcoin/Bitpay. Additionally the Winklevoss COIN etf. Porn Industry slowly adapting Bitcoin. User Friendly Software to interact with Bitcoin is slowly being released for the general masses. |

Maybe we really are at the bottom, the troll quality is definitely at an all time low.
Ugh its so exhausting watching the price, I just got 2/3 back in 1/3 last night 1/3 this morning. Waiting for awhile for the last 1/3 to see if it will go down below 300. |

With the news on USB firmware hacks I was wondering if I should add a 3.5" floppy to my online computer to transfer from my cold storage old XP computer that already has a floppy. Would it be safer?
Some people recommend storing the keys/wallet on a DVD/CD. |

Everytime I want to buy BTC at a low price it jumps right back up!  Can never time this dam volatile currency... yeah, thats true. honey badger is a tough motherfucker. Slippery albeit coated in honey, patience  |

As long as it's not fake I can use it. what does it matter how many notes are in circulation?

Well we know its impossible to counterfeit Bitcoin since no one has been able to do this for ~5 years now. With bank notes/fiat it is easily replicated, they constantly update the "paper" technology in Notes to stay ahead of counterfeits, so we can assume we don't know how much spendable money their is due to counterfeiting. - http://en.wikipedia.org/wiki/Counterfeit_money We know that their will only ever exist ~21 Million Bitcoin (less because people have sent coins to burn addresses or lost the corresponding private keys that control the coins) Only way to counterfeit bitcoin is to be able to generate hash collisions for addresses that have coins, this does not really exist (very unlikely to occur), and if we manage too collide one of the hashing algorithms we are left with another hex digest since we chain two different hashing algorithms, this is so we can swap out the weakened hashing algorithm and generate new addresses and send the coins to them. Additionally Bitcoin addresses are created with 2^256 bits, we can extend this too create a larger key-space in the future if needed: 2^512 or 2^1024 etc which would provide a significantly smaller chance for a hash collision to occur when compared to 2^256 I kinda started ranting about different stuff, hope something I said is real/helpful for you, long day and too much caffeine!! |

If you don't know who created it or why it was created?
Math is what provides the sense of security for me, Math is almost always predictable. |

The idea is amazing as is the technology. Why is there such a instant rejection of the idea? It can literally start arguments with what I see as intelligent people. I don't get it.....
Education, most people can't comprehend the impacts of what Bitcoin has solved, possible applications etc. Fact of the matter is it took nearly 1/4th of a year of next too constant research for me to feel comfortable with the majority of Bitcoin's ideas. After hearing about how Bitcoin works from people for nearly a year and a half I still am able too learn new things about the protocol. |

Hi Guys,
MY ADDRESS IS NOT ON BLOCKCHAIN.info
Every address that's valid is on Blockchain.info, it just displays a copy of the blockchain. If you ever made transactions on the network with the address its known by anyone who looks at any copy of the blockchain, whether it be loaded from Bitcoin-qt/Blockchain.info/blockr.io etc Anyone can write a program that just grabs every address involved with every transaction and sends dust to them. Probably what happened to you, the only thing stopping this kind of attack is the fact that most miners will ignore transactions with small fees or no fee at all. So these dusty transactions will most likely be ignored by the network or a long while to be mined into a block. |

If someone controls a couple nodes (10 for example, shouldn't be hard to do that right?), and at some point he isolates those nodes from the other bitcoin nodes, that will lead to an isolated blockchain that only he have access to it, and if he mines on it at 1kh/s or whatever super slow hash rate, at the time of recalculating the difficulty, it'll drop down by huge amount considering there wouldn't be any new blocks found between the time he isolated the chain till the time of changing the target difficulty (maybe he waits for 2 recalculating events, or modify something to make the difficulty drop to lowest possible not sure how possible that is). After this new low difficulty, he uses high mining power to create blocks at very high speed since the difficulty has dropped (on his own blockchain), meanwhile the true blockchain will have generated blocks that aren't included in those isolated chains, but due to him having low difficulty he generated twice the amount of blocks (or maybe x1.5 for example) if he then releases those nodes and they start interacting with other nodes, will this "self generated" chain become the "true" chain? I mean since it's a longer chain wouldn't it be the "true" blockchain? and that person would have actually reversed some transactions, and also generated new blocks and took the reward for himself?
I got this theory while reading an article about selfish mining, but for selfish mining to work you'll need to have something around 25% hash rate? (can't remember the exact %)
Anyway, the idea was taken from selfish mining, but I added that attacker needs to have couple nodes under his control and he isolate them in order to massively reduce the target difficulty so he can generate blocks at ridiculous high speed to make up for the time he didn't generate blocks while isolated.
also I'm not sure if 10 nodes are enough? maybe he needs something like 1/3 of total number of nodes to make sure that his blockchain will be published to everyone?
That's all, if anyone can explain if it's possible or not or if you can provide links to articles that help me finding the answer I'll be really appreciated, hope I explained my theory in an easy way.
Read section 11 of the Bitcoin.pdf https://bitcoin.org/bitcoin.pdfAt section 11 it talks about the scenario you are proposing, like others are mentioning it would be impossible for the attacker to keep up with the honest chain unless they had 51% or more of the network, even if they made their own chain it would grow a a significantly slower rate since the difficulty will be high and it will take many blocks to readjust the difficulty. Even if the chain was copied 1 block before retargeting, this chain would most likely remain 1+ Blocks behind because they would have to solve atleast that last difficult block before the retarget. "The race between the honest chain and an attacker chain can be characterized as a Binomial Random Walk. The success event is the honest chain being extended by one block, increasing its lead by +1, and the failure event is the attacker's chain being extended by one block, reducing the gap by -1." - Satoshi Nakamoto Additionally: creating value out of thin air or taking money that never belonged to the attacker is not possible even if they had 51% of the network. They still can't brute force your Private keys and create transactions. |

What about the project Hal was working on: bcflick - https://bitcointalk.org/index.php?topic=154290.0I have not found enough time to try to setup a machine as he describes(Maybe during holidays), however the setup he has is essentially what your talking about. Also if anyone has any more info outside of that thread on this project, I would be happy to read the information or at-least save it for when I have free time. Did anyone continue working on the project? |
|
|

any site to do that ? and what are the rates exactly  Any answer is Highly appreciated Most every user who buys Bitcoin/Sells Bitcoin with Paypal often gets scammed or scams the person. They just do a charge back on the transaction and walk away with the Bitcoin, since Bitcoin's transactions can't be "undone". If your going to buy Bitcoin checkout: LocalBitcoins, Coinbase, Circle |

Thank you everyone for your replies.
I was just in the middle of checking circle.com out.
$2.93 more expensive than coinbase at the moment. Not bad at all. I was pretty much looking for anything under 2% of coinbases price.
Thanks again!
Take a look at BTC-e, typically they have the lowest price from what I have noticed. Its been that way since back in the MtGox days. |
|
|
|
I notice on coinbase, for example, the btc price is currently 385.97.
Then I head over to google and it's $385.33.
No big deal, I can see why they differ.
But then I go to buy some at localbitcoin and notice that people are selling it for $407-620.
Why is that? And is that normal?
Is there anywhere else that's good to buy bitcoin in the world that's closer to the actual price? ie - minimal fees.
This should probably be posted in the Beginners board: https://bitcointalk.org/index.php?board=39.0However the reason why the prices vary is all exchanges are independent from each other, their is nothing in the Bitcoin protocol that links it to a USD Value. The price of a Bitcoin is what anyone is willing to accept it for, all of the exchanges have different values but are relatively close usually within 20 dollars at most. Just depends on the orders available on the exchange what the current price will be displayed as. Also why Localbitcoin is so much more money, because you can truly be anonymous and purchase coins through Localbitcoin. Exchange Cash for Bitcoin without needing to fill out any paperwork etc identity election to companies such as coinbase, circle etc. |

Looks like its the Laxotrade spamming account, search the forums for the word: Laxotrade several people have already created threads about this in the past. |

Ebola is heavy in the news, EMC2 is considering leading a campaign to making a public donation to fight Ebola -- via Ebola research, public awareness, and scientific education.
We need to know many people are willing to contribute to the campaign, we want you to pledge your support. We are specifically looking for people to pledge currency, volunteer time, retweets, facebook, reddit, IRC, etc posts, and assistance with a crowd-funding campaign. If enough people pledge to do something great in this regard we will turn the best wishes into action.
In addition to the good it will do for the cause, it will also provide some positive exposure for the cryptocurrency community, we know that various media inside and outside of the CC community will want to pick-up the story.
Depending on the number of people who would want to be involved this project will be very impressive.
We want to help fight Ebola, can we count on you to support this cause?
You should create a fundraiser and donate all the proceeds to Ebola research/public awareness. http://kryptokit.com/rush-fundraiser/http://rushwallet.com/ |

I investigated this subject a couple months ago and came across this useful post.
Thanks U! Great thread. The thing you need to remind yourself while researching this, like franky1 was saying: 1 Address != 1 User of Bitcoin Let us propose a situation, what if I sent small amounts of Bitcoin to 600 addresses that I have the private key for. Does that makes me 600 people for all the wallets I have? I am but one user |

I just logged in for the first time in 6 months... and it says "Please withdraw coins ASAP, shutdown procedures will start in the coming weeks"
I have MEOW, LEAF, and VTC on there... even though they are essentially worthless, where can I move these to?
Please respond
Like others have suggested you should probably just move them too Cryptsy. |

We are FORCED to pay a tax upon every transaction, and they say Bitcoin doesn't have any taxes? That's just pure crap. Taxation is unconstitutional theft via armed extortion. In Bitcoin's case, it's unavoidable, and is without the armed extortion (YOU ARE FORCED TO PAY).
You can make a tx fee nothing, you can determine what fee you want to send, but some miners will ignore your transactions if they are too small. If you paste it straight into Blockchain.info I think it might get mined in a few blocks even with no fee. Some pools are more liberal and pickup any transactions, some are more strict and only take transactions that have good tx fees. |
