i get this error "Cannot contact reCAPTCHA. Check your connection and try again."
and some times when solve it right i get wrong answer (i get same pic when register and when sign up solve boxes work in register and get error when sign in )
This happens to me when using Tor a lot of times, so to the annoyance of the captcha itself, and to the annoyance of having to turn on then off javascript to log in, you have to add the fact that it takes several attempts of changing IP with the "New Tor circuit for this site" option a bunch of times until you find one that Google hasn't banned. So yeah, not very Tor friendly this reCaptcha. |

Honestly, I don't mind the captchas, and they are not that difficult, but I've only ever seen captchas in the login page... (?_?)
The login page is the only page it is on.  Do you know how to set a noScript exception on the login page only? When I try to put the login page url, noScript automatically adds "bitcoin.org" as an exception it's entirety. It looks like you aren't allowed to add subdomains. I hate solve the reCaptcha, but manually turning on and off javascript is an added annoyance that could be automated with noScript, if noScript allowed to add the login url. |

adding images here there is two different count down timer one is 1 day 20 hours 15 minutes the other FAQ page is 2 days 20 hours 15 minute? which one is correct was thinking of buying btc at time of fork now i m totally confused. https://imgur.com/a/H8RuIhttps://imgur.com/a/lHr59You are not going to be able to access your bitcoin gold coins well entered november I think. Just because the fork happens in 3 days, doesn't mean you will access the coins in 3 days. Apparently there is a premine, and since this is a fork, it means that they will mine for 3 weeks or so and then the real thing will start. It is a premined shitcoin anyway, just dump it when you have it, same goes for S2X. Wait for S2X fork to happen, then access both forks with only one move in your cold storage. |

what is the use of gas ? It is also only for trading ?
As far as I know, gas are fees in Ethereum. The more gas you pay, the faster your transaction gets mined. Not sure what the role of gas will be once Ethereum goes Proof of Stake tho. Example of gas usage: In the ICO's, rich whales used tons of gas to get their transactions go faster than the rest and get massive stakes on ICO's, so a lot of non rich people weren't able to buy the most hyped ICO's. |

Just ignore it and do your thing, there might be a mild delay one day but that is the worst of it. These are just a bunch of drama queens and the fact that they whine about it makes it more visible. It will be fine and another new ass coin will pop out with overwhelming people behind it for no reason other than talk. Rumor built coins never last forever.
I'm guessing it will fail, but there is a slight chance that the Bitcoin chain could become "stuck" with extremely slow confirmation times and prohibitive fees due to long block times. In that case, there will have to be a POW change or at least a difficulty algorithm change that will require a hard fork. Unfortunately, this isn't like 2013 where the community was quite unified. Now, the community is fractured and I'm not sure there would be widespread agreement on a POW hard fork. I fear that a lot of users would opt for the 2X chain in such a situation. Its the "stuck" bit that worries me too and also the replay protection or lack of. Will it be the case though that we wont have any idea how much hash rate is on either side until after the fork. I am still confused how Ver is supporting 2x when he now claims that Bcash is the true bitcoin? It truly is sickening as btc hits new All time highs that they may shoot the golden goose Indeed, signalling is just that. It supposedly shows intent, but miners have no skin in the game until the fork has occurred. If the futures markets are accurate and B2X is only worth 0.15BTC a piece, then they will be losing a lot of money by mining it. Then again, it's hard to say if the market is properly pricing in the possibility of the "stuck" BTC blockchain, and if people truly believe the NYA signalling is accurate. I think the market believes that the fork is unlikely to happen since there is such lack of consensus. But the market is often wrong. I'll have my popcorn ready and my coins on ice when the fork happens next month. I'm also confused about the position of Ver, Wright and Jihan Wu. Supposedly Bitcoin.com and Bitmain are backing B2X, but they seem to be gung ho on Bitcoin Cash. Wright doesn't seem to support Segwit2x at all, or if he does, only to strengthen the position of BCH. Im not worried about what the market wants, but what they can do with enough hashrate to the legacy chain in order to avoid the market showing what it wants. In other words, they could launch an attack, given enough hashrate, that could render pretty much impossible to let the market dump the 2x shitcoin. This is why they don't want exchanges to support both coins, and let the legacy chain process these transactions. This is one of the biggest attacks on bitcoin we've ever seen. Im just hoping we aren't forced to change PoW, because that would be defeat in a way. |

It is not letting me withdraw funds from my EUR Wallet in COINBASE it's telling me ''Before withdrawing funds, please verify your bank account.'' And im pretty sure it's verified since I use it to make my purchases lol!! anyone can help me deal with this bs? regards Undecided
In most cases, this is how one should proceed: 1) Write to Coinbase support. Post the reply here. 2) Someone will be sure willing to look at your case and help you out. 3) If Coinbase is replying with some bullshit, make a thread on Reddit and shame them in public to pressure them against a community of 350,000+ people. You said you use it to make your purchases. You mean you have bought bitcoin in Coinbase before? Have you ever withdraw before? |

Economy / Economics / Re: UBS: Cryptocurrencies Are a ‘Speculative Bubble’
|
on: October 21, 2017, 05:29:26 PM

UBS has said that cryptocurrencies like bitcoin are a ‘speculative bubble’ and are unlikely to become a mainstream currency. Yet, it believes the blockchain may have a ‘significant impact’ on many industries. In a white paper titled ‘Cryptocurrencies – Beneath the Bubble‘ that was published this week, UBS said: We think the sharp rise in cryptocurrency valuations in recent months is a speculative bubble. The bank added that it was ‘doubtful cryptocurrencies will ever become a mainstream means of exchange.’ The need for companies and individuals to pay tax receipts in government-issued currency, and the potentially unlimited crypto-money supply, pose significant barriers to widespread adoption.
Same narrative as seen by other banks that feel threatened with bitcoin. Nothing new under the sun. Let them saying it will never become a viable currency because it's volatile and not backed by governments, maybe they will eventually understand that the #1 use for bitcoin is as a better gold alternative, not a currency for daily groceries or whatnot (this may be possible with lighting network eventually anyway) |

Bitcoin / Bitcoin Discussion / Re: What happens when Bitcoin reaches its Max Supply?
|

Hi i have a question, i hope someone could answer it
As of now, the circulating supply of Bitcoin is 16.6M
I was wondering what would happen if it reaches 21M?
Will bitcoin still work even without mining?
Or will bitcoin fall apart?
In theory, the price should be so high that it is economically viable to mine the transactions profit being only the fees of them without any newly generated coins as rewards. Some theorize that this will not hold and suggest a small % of inflation. I think it's bullshit, we don't need inflation. If someone doesn't want to keep mining and reap the profits of fees, someone else will. The system will continue self adjusting just like it does now. Inflation would never have enough consensus for a hardfork. |

~ we admit that every computer that's connected to the internet is compromised,~
~ add the wallet.dat file when I need to transact. ~
i think you answered your own question here. if we assume your computer is already compromised that means as soon as you "add" the wallet.dat file it will be stolen. you are just taking additional unnecessary steps! things like hardware wallet (Trezor for instance) don't let anything leak to the outside world. they just sign your transactions for you. if you are ok with taking additional tiring steps then do this: - use your online full node to make an unsigned raw transaction - disconnect internet and boot into a live linux from a DVD - run your wallet client - sign that transaction of step 1 with your private keys. - shut down - back to online OS, broadcast the now signed transaction. some helps: http://people.xiph.org/~greg/signdemo.txthttps://bitcoin.org/en/developer-examples#offline-signingWould you still consider Trezor safe after this? https://www.reddit.com/r/Bitcoin/comments/6zgocf/psa_trezor_privacy_leak_trezor_windows_driver/Looks like you would need to boot Trezor with Tails to avoid that. Not to mention the fact that Trezor is a very recognizable device that doesn't allow for plausible deniability. If you have a Trezor, it automatically means you have BTC. If you have an USB, there could be anything inside. Also it's a single point of failure. You would need several Trezors. |

I probably won't make changes in the near future, but I've been thinking about the captcha issue, and I wonder what people think about reCaptcha.
Where reCaptcha is used now, something is required, and AFAIK all other captcha services can be OCRed and are therefore useless. End-users often like SolveMedia, but those seem really easy to OCR. I actually really like the image classification approach on a theoretical level, though I hate relying on NSA-lite Google, and occasionally on Tor they throw you into some insane black hole of difficulty (though you can change your Tor exit to fix that).
Let me stress what Theymos posted here for TOR users. I am here exclusively via TOR and have experienced the "black hole" he mentioned above. For some reason the change circuit feature on the TOR bundle fixes it. Nobody likes to stop and answer Captcha's, but if it keeps us from getting pounded on the server front end so be it! Once I go through the 30 second process to get in it runs slick for me. Good job! About Tor... the DDOS attacks are brutal specially on Tor users. I wasn't able to browse the site today with Tor at the office, so I had to wait to arrive home and try with a normal IP, it was still slow, but Tor becomes unusable and today there was a heavy attack going, I got "busy, (504) and (502)" messages. Now it's pretty decent again. And btw Tor got updated today and the noScript button is back so turning javascript on and off is now easier. |

The reCaptcha is insanely incisive when you are using Tor. It asks you to make the "street sign" and "vehicles" ones which are tolerable, but then there comes additional rounds of "cars", which are the ones where you have to click on car pictures that fade to white in slow motion several times until the system considers you not a bot. It is honestly annoying. The fact that you have to turn on javascript on then off manually is also annoying. Btw, I don't know what the hell is up with the latest Tor upgrade, but the noScript button has disappeared. I was considering whitelisting the login url ( https://bitcointalk.org/index.php?action=login) but I can't find the button anymore. |

i don't know from where you copied this but you forgot to copy all of it! the table 1 and i am assuming much more is missing from the post you pasted  i currently have a code that does this. i also have run it for a while and also made trades with small amounts for testing. i won't deny that there is a chance of making a profit but in total the risk is way too high and the profit is so small. you will most probably end up losing a lot more. and usually the price difference is found in small exchanges. and the issue with those is that they don't have enough liquidity. the order size for example is less than 10000 satoshi sometimes! I don't think it's worth it. If Bitcoin was faster to transact, then maybe, but the result would be that exchange prices would be closer to each other because people would be doing just that. So if you want to do this, you have to do it in special circumstances, otherwise by the time your BTC arrives to the exchange you may have lost in fees and the price will not be ideal for arbitraging anymore. |

Has South Korea banned ICOs? What is implication on Crypto market ?
I don't think so that South Korea has banned ICO. It's only China and no other nation that I know. If you have any reference for the news, please share it with us so that we can also come to know the truth. However, the effect of China's ICO ban had already shocked the market initially and the price was down to $3100 level just few weeks back. But then it started recovering and we are standing at $4300 level within this short period of time. The positivity around bitcoin is high worldwide and hence market recovered very quickly. However, please keep in mind, that China did not ban bitcoin. They just banned the route of raising money through ICO. South Korea did ban ICO's, but apparently people always expect a big crash when this happens, this time it was irrelevant because nobody really cares about ICO bans anymore, at least not when it comes to the bitcoin price. https://bitcoinmagazine.com/articles/south-koreas-ico-ban-reaction-serious-concerns-over-cryptocurrency-investment-practices/These are really non issues for bitcoiners. But even if you are speculating in the ICO game, you should worry not: No matter how much they ban ICO's, there will always be ways to buy ICO's somewhere else, and there will always be chances to make money if you are buying the right thing. Unfortunately there is a lot of trash in the ICO space, but some projects are legitimate and add value, there's nothing wrong with investing on these. |

Bitcoin / Bitcoin Technical Support / Is this a safe practice?

Since I like running my own full node to transact, I need to keep my wallet.dat safe. The dilemma is, how can transacting within a full node be ever secure? If we admit that every computer that's connected to the internet is compromised, it is a hard task to keep it safe. My idea is to keep my Bitcoin Core full node client synced, but only add the wallet.dat file when I need to transact. Once im done transacting, I would close Bitcoin Core, copy my wallet.dat into my USB, and then proceed to delete wallet.dat with a software such as Eraser ( https://eraser.heidi.ie/) This way there wouldn't be nothing to steal anymore, and the only moment you are exposed is during the transaction. I was wondering if there is a device that would allow you to safely use your wallet.dat within your full node in an isolated way? Never used a Trezor but that's not what it does I think. |

I think same like today - 10-30 minutes.
Power of protocol is rising proportional.
I was not there in 2011, but I know some people that did transactions in the early days, and confirmations were not relevant. 0 confirmations were safe because of the lack of interest and resources put into a potential double spend attack, so you could instantly receive the coins and then spend them. People like Roger Ver falsely sell the narrative of this being taken away by Core devs because they refuse to raise the blocksize, what they don't get is the fact that 0 confirmations will never be safe again, and they were never intended to be a viable way to safely spend coins, even satoshi said so. Exactly, things have slightly changed from then. For now, with zero confirmation, transaction most likely won't be activated as you have to exercise patient a bit for a more liable access to transaction. Which is why we must expose on a daily scammers like Roger Ver and Craig Steven Wright aka Fake Satoshi, which are trying to brainwash people into thinking 0 confirmations aren't safe because of the blocksize being too small. Just for the record, Satoshi vs FakeSatoshi:  |

I would be interested in what you think about coinlancer? I like the idea but i don't know if there's a real demand for such a product.
Let's see... A blockchain platform for effective freelancing and secure peer-to-peer exchanges. Looks like another ICO on top of the Ethereum exchange with dubious goals. Why would you need your own token to become a freelancer? Why not just offer your skills in exchange of bitcoins? I don't get it. BTC is money, you can accept it now already for your efforts. Please explain me what the end goal for this project is then? To me, it is another excuse to create another token to sell. |
