Hello,
What is the best way to protect your coins?
Somewhere safe?  Is there any way to backup your wallet if your computer crashes?
This depends on the wallet. If your wallet does not allow you to make backup you can allways use another one and send all the coins there. Somewhere safe...What are the best practics for protection?..
Offline, physical secure and multiple copies. IMHO the best way currently is to have one (or more) paper wallet(s) that allow n of m. So you have 3 parts of a paper wallet and any 2 pieces can generate you the private key you need to spend the coins. This allows you to store those wallets in several places and any one of your secure stashes can be compromised without you loosing your coins. https://www.bitaddress.org allows this. Its called split wallet. But do not generate the keys online unless you just want to test it with a little amount. Get their code https://github.com/pointbiz/bitaddress.org or any other code that suits your needs and generate the keys on an offline machine. To ensure that the keys are not compromised later you can use a live linux to boot from. More on bitaddress can be found here: https://bitcointalk.org/index.php?topic=43496.0 |

I'm trying to backup my private keys from blockchain.info wallet. I'm trying to export them in unencrypted format. Here they are offering 5 options...
1. Base58
2. Bitcoin-QT Format
3. Base64
4. Hex
5. Leave Private Keys Encrypted
For all the above 5, the address is same but 4 different private keys are found. 1 & 5 are same. Which one should I save ?
p.s. I dont know which client I'm gonna use if BlockChain.info is unavailable. So Bitcoin-QT does not have any special significance here. I need the most general purpose one.
Safe all of them. Each private key corresponds to a public key which belongs to one of your addresses. Exporting them encrypted is probably the best for security, using Base58 and safeing them in a text file the most convenient. Almost all wallets understand base58. As a compromise I suggest you safe them in base58 in a text file and encrypt that file with a programm of your choosing. base58 should looks like this: 5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF Edit: The best course of action in terms of security would be to import the private keys into your new wallet ASAP and send everything you have on the old addresses to one (or more) newly generated address(es). Just in case any of the private keys has been compromised. This also means that you can no longer use any of your "old" addresses you got from blockchain.info. |

I've seen quite a few people taking and giving loans and stating that they were doing it to build up trust. They were quickly silenced by a justified outburst from the community. Do those people deserve negative reps ? That was my question.
If it is stated that the loan is just to gain trust in my book thats buying trust and Id give negative trust for that. But thats just my opinion. Idk, gambling habit? There might be a reason. Maybe the gambled away the other money allready or they have it invested somewhere else and need some quick coins. I usually dont care about the reasons people want loan as long as they can provide colleteral. As long as you get your colleteral you are fine anyway, so whats the point of "building trust". Its not like you would get better rates because you have 3 or 17 or 42 positive trust ratings. If people lend to someone without collateral just because they have x amount of positive ratings they are following a bad bussinessmodel anyway. I will flag any reputation loan request. It is the same as buying Trust, which is exactly what they are trying to do. It is paying for a short cut instead of building long term Trust.
But there are many easy ways for people to essentially buy trust on here. You can buy it for as little as you want if you've got half a brain. Thats why a deal should not be based on a trust rating, but allways on escrow/collateral/etc. |

I know blockchain.info is not the blockchain! I was just trying to find out fast what happened!
Corrected the mistake!
Anyone knows when the blockchain.info will be up again?
They have problems since last week or even longer now. Contact their support. How could we tell you when they sort their shit out? |

i know a reputable source that can sell u 0.1 btc for only $75. i've dealt with them persoanlly many times
That's quite a premium, even for a fractional amount. In any case it is probably worth PMing the user regarding such an offer. After being scammed already - albeit for a relatively small amount, I can't imagine that they are up for paying top dollar. Thats probably the next scam. "Bitcoin Magazin" got negative trust from a mod for not finding the alt coin section. Id argue that someone overchallenged with such a simple task can not judge whether a trade is reputable or not. |

>inb4: paypal fucks you over when you are scammed allready.
Sorry for your loss, but you could have known this. Paypal has a very bad reputation when it comes to Bitcoin and other digital good for exactly this policy.

If this is doable than I can probably do it, I just want an honest trade, that's all.
You can use the giftcard to get credit on amazon. With that credit you can make a new one. You dont have to buy something with the giftcard. It is actually recommend by amazon to redeem the card directly to avoid loss.... Ah nevermind was just searching for it when I found this: Gift certificates cannot be redeemed for products offered as download. However the redemption of the gift certificates for MP3 Downloads is allowed. Gift certificates cannot be used to buy other gift certificates.
Gift certificates or gift certificate balances cannot be redeemed for cash, transferred to other customer accounts or set against receivables. Gift certificates cannot be resold.
Source: https://www.amazon.de/gp/help/customer/display.html/?nodeId=200275500Its for amazon.de though, I doubt it, but maybe its different for amazon.com Sorry, I was sure I had done this before. |

My problem is when I set the IP4V addreess I an supposed to select " obtain DNS automaticly" But that option is greyed out in win 8.1 and I can't select it. It wants to manually input an address for a DNS server which I have no idea what the address is.
DNS is not needed if you only work on your LAN. If you connect the Antminer directly just enter 127.0.0.1 as DNS. If you contact to the Antminer via a router/switch/hub/etc. in your LAN use the IP of your router as DNS: |

You can ask Amazon who cashed your gift code and/or claim it is stolen, which is why nobody should be accepting Amazon gift codes.
I don't think that's an option, Amazon gift cards are like cash cards, if anyone cashes them, they are theirs, which is why I was worried about selling them. Even if I use an escrow, and sell it, and the buyer cashes them and claims it didn't worked and in which case the person holding the escrow would have no option but to return the BTC to the buyer and I would have lost my Amazon gift card for nothing. As I explained before the person doing Escrow can cash the card and make a new one for the same amount. So its impossible for the buyer to claim "didnt work" |

Thank you for helping me with all of my queries but I am just a little confused about this part: What if the buyer gets the Amazon GC, uses it and claims that he did not received any money in his Amazon account. In which case the escrower would transfer his BTC back to him?
To avoid this E can redeem the card and make a new one for the same amount. This will cost no fee from amazon. I just want to to make sure that the buyer doesn't frauds me by cashing out the card and then claiming that it didn't work. The idea is that the person doing the escrow (E) is redeeming the gift card. So E has e.g. 25 USD on amazon as balance and can make a new gift card for the buyer (B). That way B can not claim that the card "didnt work" because E can vouch for you. You can ask Amazon who cashed your gift code and/or claim it is stolen, which is why nobody should be accepting Amazon gift codes.
I did not know this however. So E will probably not do what I suggested. |

I dont even... words https://what-if.xkcd.com/31/-- better now. Well this might be a growing market. The blockchain is growing and DVDs can be produced cheap. Esp. in regions where you have a slow internet connection you might be faster waiting 2-3 days for the DVD. |

I am sorry but at this stage we are not ready to share it with the world. We will however release it to the world before beta testing starts as we will need alot of people to test the network. Without this, ofcourse we cant expect people to trust the system. However, at this stage we only need help with the name so that we can move ahead and get to the alpha testing phase. We expect to be in Beta Testing phase in 2 months. Also, before beta testing start, we will share the whole system with the users on this forum.
Thanks for the PM (which is identical to what you wrote here(?)). If you are still in alpha and you are concered about the name, I am not interested  |

Go for an Android device. It has the best support for Bitcoin as of today.
With the iPhone and Windows phone you never know if an what kind of Bitcoin apps you'll get and they could get taken of the appstore any moment.
There is no app on iWhatever that allows you to send Bitcoins. Apple just does not allow it. See e.g. here: http://www.coindesk.com/apple-approves-bitwallet-ios-app-btc-sending-function-blocked/-snip-
I recently purchased some coin, took a picture of the receipt and tried to attach to email but couldn't.
-snip-
Please dont do that again. Sending the code that allows you to get the coins via EMail is a very dump idea. Sniffing mails is way to easy. As state above iPhone has no App for Bitoin. Apple does not approve Android has several you can choose from but AFAIK all of them had problems in the past. Mainly because its a phone and thus not very secure. Im not talking about stealing it, but rather about the limitations of the hardware. Andoird had problems with its random number generator. If you must use a phone do not load more bitcoins on it as you would carry around in cash. Keep the rest of your coins safe at home. |

Do you have a whitepaper on how your card will work?

-snip- Did you miss the word "compressed"? You can find an out-dated compressed bootstrap file "bootstrap.7z" through my link. Yes, I did =/ Here is a version from Oct 2013. http://sourceforge.net/projects/bitcoinblockchain/files/29-10-2013/Still working and providing at least 750KB/s (im on a shared wireless conection so you can probably do better) Id rather download the uncompressed data and let my own client do the verification though. |
