Leah McGrath Goodman and Sharon Sergeant both have Wikipedia articles about them and the latter seems to be a well-known forensic genealogist. Newsweek seems like a reputable source as well.
On the other hand I find it hard to believe that someone who wanted to stay anonymous, especially someone who is an expert in cryptography, would use his real name in public. Many people have claimed to have "discovered" the identity of Satoshi Nakamoto. Just look at his Wikipedia page for example. Here's hoping that this will be just another one like the rest.

Are you solo mining or mining in a pool? If you are solo mining, then you will receive bitcoins when you solve a block. At 30 kH/s, that might take a very long time. If you are mining in a pool, then the pool's website will give you the information you are looking for.
At 30 kH/s, you are going to earn something like $0.13 per day, and that is not likely to pay for your electricity.
This guy is talking about dogecoins, not bitcoins. I think he knows that. 0.13$ with 30KHash/s in Bitcoin network per day is a dream. Yup. Otherwise my 333MH/s block erupter usb miner would be making me $1500 per day haha. Hello,
I've been mining - using CPU Coin Miner - for 30 hours averaging 30KH/s (just trying to get the hang of this) and my wallet, which has my correct address, is showing a balance of 0 and unconfirmed of 0.
Does that sound accurate? Is there a site that you can enter your address into and see how much you've mined?
Suggestions or help?
Thanks!
Rob
If you only got a CPU, you should try some CPU-only coins instead of scrypt coins. Any good ones? Looking at coinwarz, all the popular altcoins seem to be either sha-256 or scrypt. |

I use Electrum because I can't be bothered downloading the entire blockchain onto my netbook over my slow wifi.

According to the coinwarz calculator, if you are solo mining at the current dogecoin difficulty, it will take you about 5 years to find a block at 30 kH/s. BUT if you are lucky then you could generate a block tomorrow, or it could take 10 years to find a single block. But 5 years is a good estimate. Until you find a block, you won't have any dogecoins. Not sure how many coins you'll get once you solve a block though but it's a lot. The good news is that if you join a pool then you should start earning dogecoins instantly. 30 kH/s at the current dogecoin difficulty should yield about 6 coins per hour, or about 150 coins per day if you leave your computer running 24/7. |

Gotta Cryptsy Key? - I'll shoot you 1,000,000 CENT.
Hi, my Cryptsy key is: c806fe3973f4354610884641820ca119ac621822 Thanks!!  |

Are there altcoins out there where one can easily get >1 million of?
It's just for fun really. I think it would be cool seeing a wallet with a balance of 1,000,000 in it. Even if it's only worth a couple cents.
Mining isn't possible since I'm on a netbook.

What is there to prevent me from setting up my own bitcoin exchange, slowing fiat and/or bitcoin withdrawals to a crawl, and then profiting off the arbitrage once prices start to diverge from other exchanges?
If I understand correctly, bitcoins on Mt. Gox were initially more expensive than that of other exchanges because it was more difficult to withdraw fiat from Mt. Gox. So people were willing to pay a premium to withdraw bitcoins instead of waiting weeks/months for fiat withdrawals to be processed. That is, until the February crisis. Then the opposite happened and people sold off their bitcoins and turned to the safety of fiat even though Mt. Gox wasn't processing withdrawals for either fiat nor BTC at the time.
Had Mt. Gox been solvent during the February crisis, there would have been a massive arbitrage opportunity for its owners. Mark could have bought GoxBTC for ~$100 and sold them on BTC-e for five times that amount. Then once enough profit was made, he could start honoring withdrawals again and it would be like nothing had ever happened and business would be back to normal.

I can understand why some people think thieves (eg. hackers, FBI, fraudsters, etc) deserve to be punished but why punish Satoshi? Without him, neither Bitcoin nor altcoins would exist.

1. What the hell is a whale?
I think it's people who have a lot of bitcoins. Like over 1k. |

I don't know much about bitcoin security
And yet your going to make guesses based purely on what you hope? but I'm sure it must be safe security-wise, right?
That depends on what you mean by safe. It's mostly safe when everything is working perfectly, but it does increase the risk more than if you used a new address for each transaction. After all, websites like xkcd that accept bitcoin donations can't really change their address every time someone makes a donation.
They certainly can if it's important to them. Nobody is going to gain access your wallet with just an address because they won't have your private key(s).
Ask Andriod users that re-used addresses back in August. I suspect they will correct you on that matter. It might be possible to identify the owner of a bitcoin address by looking at their transactions on the blockchain though. For example, if address A receives bitcoins from address B and you know the identity of address B (eg. it belongs to a known person or a company), then you could ask them who the owner of address A is and find out their identity that way.
Yes, you certainly give up some anonymity that way. OK, as I said I don't really know much about bitcoin security so this might sound like a stupid question but how would you avoid reusing addresses if you are a store that accepts bitcoins? If you have 500 customers sending you bitcoins then you would need 500 different receiving addresses right? And what if you wanted to put all of these coins in cold storage? |

I've heard of people losing bitcoin because they threw out a hard drive. And I've heard that you can control bitcoin with just a brain wallet (a memorized passphrase). Do you need just a passphrase, or do you also need a wallet.dat file (if you're not using an online wallet)? If someone could provide a simple explanation or point me to one I'd appreciate it.
This thread might be of interest: https://bitcointalk.org/index.php?topic=488560.0I was a bit confused about this too but apparently, the private key is all that really matters. Your computer could burn to ashes tomorrow and you'd still be able to access your funds if you have your private key written down somewhere. In the case of brain wallets, a passphrase is memorized which is used to generate a unique private key but it's the private key that ultimately matters. If you lose your computer but you have the wallet.dat file backed up somewhere then that can also be used to access your wallet since it contains the private keys of all the addresses in your wallet. Some wallet programs like Electrum and Armory have a feature that lets you backup your entire wallet (ie. all your addresses and private keys) by writing down a short phrase called a seed. That way, if your computer is either lost or destroyed, you can still regenerate your wallet from this. Not sure exactly how it works though. |

...
Also, if someone is using something like the Electrum wallet then are there any differences?
Electrum's private keys are generated from a seed. Then you can get back your funds if you got that seed or the derived private key. Yes, that's all you'd need, but, here's the thing that catches most people because they don't realize how Bitcoins work, first of all, a tl;dr, "When you spend any amount of money, the money will probably no longer be in the same address".
Longer version:-
It's impossible to spend less than the amount you received in a previous transaction, but, obviously, the majority of the time you won't want to spend the exact amount of a TXIN (or multiple ones combined), so, what do you do? You send the amount you want to spend to the receiver, then, you send the remainder ('change') back to yourself, normally, on a different address, meaning the private key for the last address is now worthless.
Personally, I recommend Armory (Or any other client that uses a pre-saved seed to generate keys), as, it fights this by using a seed which you print off to generate all addresses, this means even if you receive money on an address after paying, or, send change to a new address, that printed wallet two-line long string still saves all your funds.
EDIT:- I'd just like to point out I've never used Electrum, so, if Electrum also used a pre-saved seed, just back that up (And any other required info) and you're good. This is what the Armory .pdf (you print) looks like:-
OK, well thanks for the info. I'm using Electrum so I'll probably be doing this then. |

The only thing needed to recover your funds is the private key. So yes, you would have your 100BTC back.
All the other stuff like booting from a live CD are just precautions to prevent others stealing your private key.
Oh, I see. So in order to make a paper wallet backup the secure way, I would: 1. Remove my computer's hard drive 2. Boot from a live CD 3. Connect to the Internet 4. Download a program that generates private keys offline 5. Disconnect the Internet 6. Use the program to generate a wallet address and a private key which I write down 7. Turn computer off and put hard drive back in 8. Turn computer back on and transfer coins to the new wallet address Is this correct? |

If I had 100 bitcoins in my wallet and my hard drive was irreversibly destroyed (eg. in a fire), but I managed to write the private key on a piece of paper elsewhere, would I be able to gain access to my 100 bitcoins?
An example private key I found on the bitcoin wiki is something like this:
5Kb8kLf9zgWQnogidDA76MzPL6TsZZY36hWXMssSzNydYXYB9KF
And if so, then why is the process of creating a paper wallet much more complex than just writing down the private key? The bitcoin wiki suggests downloading and booting from a live CD for example and all of the paper wallets that I've seen have additional information on them like QR codes and the wallet address even though the bitcoin wiki says that a wallet address can be generated from a private key anyway (but importantly, not the other way round).
Also, if someone is using something like the Electrum wallet then are there any differences?

The BTC/USD price has remained remarkably stable despite the news of MtGox's insolvency. It dipped for a few hours to the 400's but is now pretty much back to where it was before MtGox collapsed.

Bought my first bitcoins today: $80 worth of bitcoins at $580 per BTC. Then hours later the MtGox insolvency document was leaked. Now they're trading at ~$520 per BTC according to preev.com. Not the best timing. I intend to hold onto them for years though so I'm not too worried. |

CPU mining, and even GPU mining isn't worth it these days because of the difficulty and the availability of ASICs. You could mine litecoins with just a GPU setup though. You're about 3 years too late to mine BTC with a setup like that. This is like you walking into quarry, explosions going on all around you, huge machines big as houses ripping chunks out of the earth everywhere, and you standing in the middle of all that grasping your little brothers neon yellow plastic sand shovel, beaming brightly: "I'm gonna mine too" Haha, this is true. Avoid cpu mining. If you want to start with more hashes buy a asic miner. Cheap ones cost less than $20 on Ebay. I've heard that you'd be better off buying the bitcoins outright rather than buying one of those USB miners. |

For SCRYPT mining you need a powerful graphics card, preferably a Radeon 7950 or Radeon R9 290. You are wasting electricity mining on your netbook. There is nothing you can mine on your netbook that would be profitable, not even the CPU only coins. You are probably spending more on electricity than you will ever earn from coins. Change your hardware. See this: http://www.cryptobadger.com/build-your-own-litecoin-mining-rig/Didn't someone mine thousands of bitcoins back in the early days on an old Pentium 4? I can understand how you might need a good GPU to mine litecoins and maybe dogecoins since their difficulty is quite high because of their popularity but surely something as tiny as kittehcoin should be mineable on a normal PC? Unfortunately, this is not the case. A few years ago the number of people mining bitcoin was much much smaller. Now everyone is trying to make a quick buck by mining some coins. So your so called 'tiny' kittehcoin is not so tiny. See this: https://litecoin.info/Mining_Hardware_ComparisonAnd then do some math to figure out when you will get a block: https://www.litecoinpool.org/calc (Plug in your coins difficulty and your hashrate to see how long it will take for you to generate a block) Or just use this if it has your coin already listed: http://www.coinwarz.com/cryptocurrency (It does't have kitteh coin) OK, thanks for that. I plugged the numbers in and it says that with the kittehcoin difficulty at 2.6 and 500 hashes per second, it will take me 260 days to find a block.  |
