And this is the result of a bad laptop GPU (the one in your laptop is probably also much better): $ ./oclvanitygen 1K1773R
Difficulty: 15058417127
[1.68 Mkey/s][total 71303168][Prob 0.5%][50% in 1.7h]
I'm going to post here and ask for information I can probably find in the topic, but I'm not yet done reading the 130 pages  Where do I download oclvanitygen? Google doesn't really help me, and the one download I found looked like a shady website. I'm running Ubuntu Linux, and get around 200-300 kKeys/s out of my CPUs (depending on system load).There's one 6 digit address I'd love to find, but it takes 30 days for 50% chance, and once I find this, I'll come up with other wishes. I'd love to use my GPU (03:00.0 3D controller: NVIDIA Corporation GM108M [GeForce 840M] (rev a2) and hope to get much better performance that way. Can someone send me in the right direction to get this to work?I feel stupid now. All the time searching for oclvanitygen I couldn't find it, I type just "download vanitygen" in Google and it gives me https://github.com/samr7/vanitygen ... Turns out I had it all along, it just didn't compile. I'll play around and report performance here if I get it to work. |

I think even above $40 is possible if BTC spikes, that money needs to go somewhere and Litecoin is the best candidate there
Litecoin is the fourth cryptocurrency when it comes to market capitalization, so why would Litecoin be the likely candidate? |

Having too many paper wallets might pose an operational risk. The risk is that you might lose some of them or even forget about those that have too few BTC. If your private key generation method is solid there is really no point in having more keys than necessary. I still want to make paper wallets, and I was thinking of keeping a PDF as a backup, of course with a decent GPG-password, and still in an offline location. One thing I only recently realized is that a paper wallet needs to be spend at once, as it's unclear where the change would go to. And after using it, it's no longer considered cold storage, as the private key has been used, so you need to make a new one. For this reason it is useful to make several paper wallets, so you only use the amount you need and leave the rest untouched. |

And yet you keep coming back  Don't blame the host for your gambling addiction. Yet, no one besides you understands what exactly the proof you brought forward is supposed to highlight.
He's must think 88% bets can't lose. Just like he must think Martingale has a higher chance of doubling than going all-in at once. |

I use offline wallet on protected USB stick with linux OS.
Do you make backups of that stick? I recently had to replace a 3 year old good-brand stick, because it simply stopped working. This stick contained movies, if it was bitcoin it could have been an expensive loss. |

I do not understand why we have to pay for 4 cent per transaction tough, isn't that too much?
Around the year 2140 the block reward is gone. The years before that, it's like 4 satoshi only. The design includes for more and more transactions, hence and increasing miners fee, to replace the block reward. Currently the miners fee is around 1% of what the miners get, in the future it will be a larger percentage. Who decides the 0.0001 should be the optimal miners fee? It's an open market: miners are free to pick the transactions with high fees first. |

Litecoin is incredibly undervalued.
It should be at least $14 right now, that is; BEFORE THE TRUE EXPLOSION/MOON RACE STARTS.
LTC minimum $18 this year. Could reach $75.
I don't think this will happen, but just in case I hold a few LTC in my wallet  |

I was wondering about the same thing, as I've recently joined my first signature campaign. I have known they exists since I joined bitcointalk, I just didn't know it pays that much for doing the thing I do anyway: posting!
And as any other advertising, they wouldn't do it if it wouldn't generate profit.
You could use an existing signature campaign with your own referral link, so you can see exactly how much visitors and possible earnings it generates. Of course you can't do this while you are in an active campaign, as the referral can't be changed when you're in a campaign.

Am i right in saying that wallets exist without bitcoin core knowing about them? Yes i think i am right in saying all the bitcoin public address technically exist anyway and so do their private keys, most of them just havn't been used yet Most of them will never be used. http://directory.io/ shows all possibilities, and the number of pages nicely illustrates how unlikely it is to find the same private key twice. |

A smart contract is an app that sits on the blockchain and waits to be called. It will only run if it's requirements are met. That's about it. You can write code so that the app is intelligent. I can see why it's called a smart contract but the terminology can be confusing. They're just apps (or dapps - decentralized apps).
If this is too simplistic then correct me!
I watched a presentation about it on Youtube: https://www.youtube.com/watch?v=U_LK0t_qaPoThe guy presenting more or less says "we don't really know what it is", but the possibilities are amazing. Half way through the presentation I got a Skynet-feeling: "a world wide computer that cannot be turned off or reset". But of course it's not that evil, it just runs very small pieces of code. Regardless the price, I'm going to experiment with the scripting language. |

My Arabic speaking friend told me that world Islam itself means "PEACE"
http://muslimvoices.org/word-islam-meaning/ says: "In Arabic, the word “Islam” means submission or surrender " and "a Muslim surrenders his or her will to Allah in return for peace". So it may give peace to muslims after giving up on free will, but what about the rest of the world who doesn't believe it? |

How did you double spend it? I sent the transaction from blockchain phone app. You think it's possible to double spend?
I extracted all private keys (3 in my case) connected to the inputs for the transaction from my bitcoin-qt client, imported them one by one in an empty wallet, and spend it from there. It took some time to be picked up by the network from there. I assume you have some way of getting your private keys. But it may be easier to at least wait a bit longer, it took me 2 weeks before I gave up waiting. |

So is there a way to verify in a away your wallet so no one else ever use it even if generating the same wallet is extremely low?
Correct! I have some trust issues though with offline wallet generators, say a paper wallet generator, or the vanitygen-master that generates a public key starting with for example 1Loyce. Without totally understanding the source of the program, how can I ever be sure it uses a random search for a new address? Untrusted software could generate predefined keys, so a third party can access it too. And for me as a user it is virtually impossible to know for sure what software I can trust. |

I used to send zero-fee transactions all the time, but I gave up on this a few months ago. I had a 0.1 BTC transaction waiting for more than 2 weeks. In the end I Googled how to double spend it (with a fee) from bitcoin-qt core client. This was quite a challenge, but it did solve the problem.

WHAAT? Coinbase pays $25 per referral? Never knew that.I'm wondering I should also start my thread here offering $5 for each sing up under my link.I'm sure there would be 100 other terms on withdrawing those referred amounts.
This got me curious. I found this on coinbase.com: If your friend visits coinbase.com/buys and purchases $100 USD or more (or 100 EUR, or 100 GBP, or 100 CAD, or 100 SGD) of bitcoin, you both will receive $10 (or 10 EUR, or 10 GBP, or 10 CAD, or 10 SGD) of bitcoin when the buy completes. Buys can take up to 4 business days to complete. |

I've folled and read this entire topic, and my opinion is still the same: Bitgold has a great product, a modern "digital gold standard", but I don't trust them. For one, they're not a bank, so the normal rules and government regulations (for banks) don't apply to them. Second, they seem unable to handle their core business. They say all their gold has a physical equivalent in a vault, and yet payments can get a charge back, which makes is useless for any transaction. Users have even reported negative balances, and I know for a fact "negative physical gold" does not exist, which means it's nothing more than a number in a computer instead of the physical gold they claim. If you want gold, there are many cheaper and less risky ways. I agree. The good thing about Bitgold would be an easy entry to the gold market. If only a local shop would sell 10 gram cubes |

A free burger Looks like a nice deal and it seems like Netherlands is supporting bitcoin considering more than 100 venues accepting it.
And this 100 is just in one city! I live in the Netherlands, but have not been to Arnhem in a while. It's the first time I hear about "Arnhem Bitcoin city", and I will for sure use Bitcoin to pay once I'm there. |

The first big drama is the block size increase from 1MB to 2MB or higher. If it is resolved, the price will rise a lot.
Doublling isn't much in a world where 10,000 times more transaction can happen. Bitcoin has some fundamental limitations that aren't easily solved, especially since the people involved have different opinions and interests. Last month a core developer quit, he has an interesting story to read: The resolution of the Bitcoin experimentI don't dare make a 2020-prediction for Bitcoin, it can be anywhere from forgotten (although I think 2020 is too early for that) to sky high. |
