I recently bought some bitcoins after taking an online course. Each of my purchases has an address, so I thought I would be able to go to a block chain browser site, put in one of the addresses, and see info about the transaction in which I bought some bitcoin. But what I always get back is 0 transactions and 0 bitcoin value. I've tried this at two different sites using 3 different addresses.
So I'm confused. Does this mean that the site I purchased my bitcoins from (coinbase) isn't actually submitting a transaction to the bitcoin network when I buy coins?
Or is it that what I am trying to do doesn't make sense? I thought that if I own bitcoins, then somewhere on the block chain there must be a transaction where somebody transferred some bitcoins to me, or rather, to the address created for that transaction which I am able to access when I log into my account.
Is there a way after buying some bitcoin to verify those purchases by examining the block chain directly, rather than relying on the site at which you make the purchase?
Go to the transaction in your Coinbase account, click on it and see if there is an 'advanced details' link. If not the transaction was 'off-chain'. |

Get a cheap pc/laptop that never see the internet. Install a wallet via usb
But if you choose only that way then it can be unsafe. Because if this pc stops working and you don't have any other backup then you already have lost the bitcoins. At least 2-3 backups you should have, 1 usb, 1 paper wallet, 1 pc/laptop etc.. also the fact that everytime you need to spend your coins you would need to start up your laptop, meaning if you go outside and find a merchant that accepts bitcoin you wouldnt be able to pay them because your laptop would be at time. the same logic applies for paper and usb wallets  , i like bitcoin but i dont like the fact that it needs to be locked away to be safe, You won't walk on the streets with all of your bitcoins in your wallet I guess. This is the reason why bigger mobile wallet providers offer a so called cold storage (XAPO wault, etc) next to your everyday spending wallet. It's like you only take a little amount of cash in your leather wallet in your pocket, the rest of your money is in the bank, in the safe at home or in your pillow  In this case you can manage your everyday spending of your bitcoins from your mobile wallet with a lower balance and the rest of your BTC can be safe in cold storage or in phisical storage like Trezor. But most secure in the sense not vulnerable from cyber attack or system crash. To solve system crash, we must need multiple back ups. To prevent attack or hacking, we must go with strong encryption with long multi-character set password. If you want the most secure wallet, what you want is to have it on a offline computer. Does not get any better. And the wallet best suited to make signing transaction with a offline computer the easiest is Armory. You just insert usb key, and let it guide you through the process of importing and signing the transaction with the offline computer. It never connect online, so its the safest. If you want to do cold storage using two computers at the moment Electrum is your better choice. It functions just like Armory with online/offline wallets. Armory 0.93.2 will not work with the latest Bitcoin Core 0.11.1. Armory signs HighS while 0.11.1 mandates LowS. I have used both Electrum and Armory for cold storage using two computers and have to tell you that Trezor is easier and cheaper. It works fine with latest Electrum 2.5.1. When working, Armory as a fully validating node does have a privacy advantage over Electrum because the Electrum server you use knows which addresses you are using. But Armory is no more secure than Trezor. If Armory (or Bitcoin Core) ever supports Trezor that would be the ideal combination for privacy plus security. Until then I am fine using Trezor with Electrum 2.5.1. Heck, if you cannot afford $99 for a Trezor the Ledger Nano with Starter USB is only $40. Both are proven and work with your phone. |

Hey guys, I'm trying to get into the mining game and I don't know what is better, should I buy mining hardware or should I look into cloud mining? Or, maybe both? Also, where would I start with either one? Does anyone here know of any Legit cloud mining companies? I have no idea what the cost of electricity is where I live, can someone tell me how I can find such information? Thank you in advanced!  Check your power bill to find out how much you pay per kWhour. The most efficient consumer miner you can buy at the moment is the Antminer S7 by Bitmain. Not really a home miner unless you have a dedicated 220v line you can use in an air conditioned room away from your living space (noisy.) You can buy hosted S7 hash directly from Bitmain Hashnest, I think your best choice if you want cloud mining. You can invest less than a hundred dollars and sell your hashing power at any time. You could also consider S5 hash. Avoid companies like Genesis Mining: their daily maintenance fees are double what Hashnest charges and you cannot sell your mining power once you buy. Hope this helps. |

I don't think using a Bitcoin wallet on a totally obsolete OS (with no security updates) is a good idea.
If that PC is conected with the internet, you are putting your bitcoins in a serious risk of being stolen.
That can happen on any computer, password protected wallet or not. You need to get your private keys off of a computer with an internet connection. |

As soon as I saw 99bitcoins there I knew what was going on. The website is riddled with advertisements, affiliate links to ponzi and pyramid schemes and links to faucets. Their affiliate marketing involves reeling newbies into believing that bitcoin is an exchelent money making machine but the only one that ends up profiting in the end is them, the owners of this website. Because really, their source of income isn't affilate marketing, they wouldn't have seen any income if it weren't for their website. And to be honest, it isn't a website that started from zero. Significant amounts of money were invested into creating it and it was likely running on lose for some time but that's what they don't want you to know. They want you to think it's all great and pay them €215 more.
99bitcoins is a self hosted Wordpress site using a $59 SmartMag theme. Ofir put it up himself, the only other costs are hosting and perhaps he paid someone to create the logo. It is not a complicated project at all. Total start up costs including hosting for a year would have been about $500. |

One step at a time. Bitstamp price is above 200 week SMA on weekly chart which is usual TA definition of a bull market:  300 is a significant barrier of course. If 300 is taken out on convincing volume and chart action shows 300 level has become support that is one more confirmation of a bull market in progress. There is also a good chance we could remain in a 200-300 trading range. We all hope not of course:) Except the permabears. |

If you own a good blog or website you can make four or five figures every month.I own http://wapinter.net and http://fbwhatsapp.in and I am making four figures every month with advertisements.The best part is I dont have to update it daily Both those sites together have less than 700 daily page views. A good rule of thumb is you need a minimum of 10,000 visitors a day to make anywhere close to $1,000 a month. Most sites need more. |

I did and got this reply: We apologize for the delay in shipment. Due to an unexpected issue in areas with weak signal strength in some areas we delayed shipment for a few weeks. We are issuing a statement in the next few days to all of our customers with a detailed plan for shipping the final devices. Signal strength is not a problem where I live so a cut and paste generic response. I suspect there are more problems with the first production run. The overheating charging pads a reviewer already mentioned would also have to be replaced. Case definitely needs to be more open with customers who pre-ordered. |

Thanks much appreciated. I wonder when released if the price would cause S7 price on Hashnest to tank. I have been waiting to buy S7 but not at the current premium demanded by sellers.

Interesting rumors on imminent introduction of antminer S7 'lite" hashing at 3.5 Th
Speculate on price...
My take: ~3.5 BTC initially ($1000), eventually down to 3 BTC.
Links please. |

Do you have to use an orange skin? I think most folks like the blue grey of the current forum, easy on the eyes. Or at least give users the option to switch skins.

I ran the new 2.5.1 .exe on my Windows 7 system. It ran my Trezor based wallet and it ran my software wallet. I also ran this version on my Windows 8 system, testing it with my Trezor and it worked OK. I did message signing tests and sending tranactions with the Trezor.
Looks good! Thanks, Thomas!
Which 2.5.1 did you run, the one Thomas posted earlier i.e. the test one or the electrum-2.5.1-portable.exe ? Just want to check because if it was the portable one then something must be wrong with my setup. Just tried sending from it again and nothing happens when I press on the send button. modification date 10/23, MD5 DEB41AC7004E6C6C5B514E0C34C68664 electrum-2.5.1-setup.exe This is a Windows installer, not a portable version. (I can confirm that it runs on two of my systems using Trezor, but these systems had previously installed, Python Trezor,Cython, Libusb etc... which I did not uninstall, so it is conceivable that these images might not run on a plain vanilla Windows.) I sent and received funds on my Windows 7 installation using a software wallet and a Trezor wallet. All four combinations worked. Also, I verified that sending funds to a payment protocol request works. I think you are confusing the portable version electrum-2.5.1-portable.exe with the Windows installer electrum-2.5.1-setup.exe. Windows installer will store electrum data locally in %appdata% portable does not. Portable version can be installed and run from a USB drive or in an encrypted container and will not write to the host computer. |

So let's say I go to Bitaddress.org, do the offline thing (namely, download the HTML code, run it on an clean machine). I use the BIP38 encryption and I use a decent passphrase with a couple of special characters.
Is this good for cold storage? I would like to know because if this is good to keep Bitcoins long term, I don't really see the point of hardware wallets. I would rather trust encryption backed by a good ol piece of paper (wrapped on plastic to avoid deterioration).
You want a paper wallet you can really use day to day? Get a Trezor or Ledger and write the seed down on paper as recommended, store it in a safe place. Enjoy the convenience. |

Not sounding good. I hope you take care to warn Armory users not to upgrade to latest Bitcoin Core 0.11.1.

I'm going to South America soon on a vacation without access to fast internet and I'll only take my smartphone with me. If, in the unlikely scenario that the bitcoin price rallies to $10k or $20k, I want to be able to do this: - Run to a store, buy two laptops. One offline and one online. Open up the offline computer, remove the wifi chip.
- On the online laptop, download my encrypted Armory wallet from DropBox. Burn the encrypted wallet, as well as Armory, on a CD and bring it to the offline computer.
- Using the normal Armory methodology, broadcast a transaction to send some of my bitcoins to my exchange account so I can sell them, without having to download the whole blockchain on the online computer (because that could take months on the slow internet).
Does Armory allow me to do this somehow? Why are you going to this hassle for a low probability event? Get a Trezor and set up with online myTrezor.com and transfer bitcoin sufficient for your vacation to your Trezor. If you have a late model Android phone with OTG ability you can download Mycelium on your phone and use Trezor to sign transactions. Armory cold storage is not the only secure way to store and spend bitcoin, just the most private right now. If you choose DHL shipping when you order a Trezor you will have it in two or three days. What about this: - Create a new Breadwallet wallet on my iPhone.
- Put the recovery seed (12 words) on Dropbox, in a file encrypted with a password.
- Transfer the bitcoins I'd want to sell onto this wallet.
- Reset the Breadwallet app and go to South America.
- If that unlikely event occurs, just reset the Breadwallet with the seed on Dropbox, transfer them to the exchange and sell them.
How does this method compare with yours, in your opinion? (I'm just trying to avoid buying extra devices. Already have an iPhone. Update: I just realized my original method involved buying two laptops LOL. Anyway. I'm kinda liking my Breadwallet idea now. Looking forward to critiques.) Trezor does not work on iPhone. They refuse to pay licensing fees to Apple I think. I would never keep private keys for more than a few bitcoin on an insecure device like a phone. You could just use Trezor with your laptop while on vacation. Trezor works with OS X 10.8 or better just not on iPhone. |

I have no problems sending or receiving with Electrum 2.5.1 portable. Clear enough? Try again, delete and reinstall from a fresh download.

For affiliate programs or Adsense to make decent $$ you have to get major traffic to your website. That takes time, a lot of work and writing quality copy. Another approach which may appeal to you more is to make a YouTube channel for a niche market and create engaging videos which solve a problem for someone.
