Hi all, sorry in advance if this is a silly question, but am bit of a newbie to this - please can someone advise me on how I transfer bitcoins from my wallet (using Electrum 2.3.2) to my bank account? Do I need to change/sell them back to GBP first via localbitcoins or similar site, or is there a way of transferring directly from wallet please? Thanks in advance  you can order Bit-x debit card and u can use it on any ATM. Your card is tied with your BTC balance in your Bit-x account. You send BTC to your account and then withdraw GBP on nearest ATM machine. Bit-x will convert your BTC to GBP at current exch. rate. Then you go with money to your bank, and make deposit to your bank account. |

I think Genesis Mining is the best and the only one   Bit-x is also good for mining. I receive message on my cellphone everytime when mining reward is credited to my account |

I will give them paper wallet with some amount of BTC, and say its a new form of money.
On other side of paper wallet, I will wrote links to Bitcoin Wiki and Bitcointalk,
so he can educate and learn about BTCBTCBTC

Forget about that, you will pay more for elect. bill than you
can earn by mining with your PC.
Even with special mining hardware, its hard to back your initial
investment and earn something

This website also generate and publish private keys. www.coinfind.cfNew archive with 100,000 priv. keys are published every day. But seems like this is for good reason, creator of that website drop some BTC to 5 addresses for others to find. |

Someone already create www.directory.iobut I think this site is only prank Its good that guy who make this site didnt implement address search option So is it his website real or just fake? Do we have to worry about is? Yes, this site is real. Do we have to worry? maybe yes, maybe no But with a private key you can acces the wallet or not? You have acces only to ballance in that address, not all bitcoins from addresses placed in same wallet |

Given your example of 1 billion users at 10 addresses each:
There are 2^160 or about 1,460,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000 possible addresses
In your scenario, 1,000,000,000 people are using 10 addresses each for a total of 10,000,000,000 possible addresses
10,000,000,000 / 2^160 should yield the probability of a collision occurring
10,000,000,000 / 2^160 = 0.00000000000000000000000000000000000000684
So the chances of a collision occurring in your scenario are approximately 0.000000000000000000000000000000000000684%
See why we don't consider collisions an issue?
The probability of a collision is found by a standard formula: p = 1 - k! / N k-1(N-k)!, where k is the number of hashes generated (100x10 10x10 3) and N is the number of possible hashes (2 160). This is a difficult number to calculate, but there is a good approximation: p = 1 - e -k(k-1)/2NBut even that value is difficult to compute because of the precision needed. Here is another approximation p = k 2/2N. So the answer is that the probability of at least one collision is approximately 7x10 -19 or 0.00000000000000007% See: http://preshing.com/20110504/hash-collision-probabilitiesOk, new data, will recalc everything: - probability of getting struck by lightning in any given year: 1/280000.
- probability of taking a shit at any given point in time: 1/(60*24) = 1/1440 (assuming you take a crap every day and the actual process takes 1 minute)
- probability of getting struck by lightning while taking a crap in any given year: 1/(280000*1440) = 1/1.47E11 = 2.48E-9
- probability of taking a crap while being in a situation where being struck by lightning can actually occur = 1/1440 = 0.25 = 1.74E-4
- probability of finding a collision: 1E-65
- getting hit by lightning while taking a crap for how many years in a row is equally probable as finding a collision: log(1E-65) / log(1.74E-4) = 17.3
is my math roughly correct now? If so, I can say: "Finding a collision is about as likely as being struck by lightning while taking a crap every year for 17 years in a row". -snip- What you people think about that? This can become a big problem for Bitcoin in the future... no? I am a little scared There is nothing to be scared of. Lucky guy get others' money. Isn't it cool? Muhammed thank you for all this info =) |

So you bought this account just recently?
No way you could have been a bitcointalk member for 2 years without ever reading this frequently (asked/answered) question.
The risk is non-zero, but small enough that you don't need to bother (unless you're using software with a broken random number generator). If you bother about duplicate private keys, you should bother more about the possibility of being eaten alive by an ice bear or drowning in a soup bowl - both events are much more likely.

No, its my account. I know about bitcoin for 3 years.... but never read / think before about this possible problem. |
