Thanks guys  So if I wanted to, I could take my wallet address and private key from bitcoin-qt and import into blockchain (or any other online host which allows imports) and spend its contents?? The software (if offline) or hosting website (if online) is actually irrelevant as they are only means to send, receive and view your bitcoins. All I need are these two pieces of information. Yes, that's correct. (You could even do with only the private key, the address to receive coins is derived from it - it just doesn't work in the opposite direction). The other thing I haven't seen much information about is a sandbox where you can 'play' with virtual bitcoins and get to know what you are doing without risking your real bitcoins.
Does this exist? Has anyone come across such a thing?
There is a Bitcoin testnet, but I haven't tried it. Most faucets/free sites arent that good to test that stuff anymore, they give out too small amounts, it takes a week until they finally send something or they just give nothing. I did a lot of my tests with transactions from bitvisitor.com, maybe this is still good to go. Just make sure it's enough to pay the fees (usually 0.0001 Btc) per transaction. Or you could buy e.g. 0.5 Bitcoins and use small amounts to test all you want to. |

Könnten auch 0,0005 sein...egal seid mal nicht so geizig...man hats ja  Davon möcht ich mir aber später noch ne Yacht kaufen ;p |

0,005? Das ist aber ganz schön viel. Sicher, dass es nicht 0,0005 sind?
Beim bitcoin-qt beträgt die Transaktionsgebühr normalerweise 0,0001 Btc, früher waren es mal 0,0005.
Läuft auch ohne Probleme damit.
-> 0,0001 Btc sind eigentlich genug.

[off topic]
I'm only answering because you asked, but this is way off topic and doesn't belong in this thread.
They are basically an AM clone (business structure wise) now with 62.5 x the number of shares. The big news is that they are in the process of paying their NRE for their 28nm chips. Everyone thought they were a scam and would run off with the NRE funds, but as that isn't happening the risk baked into their share price is now burning off.
Now back to the AM discussion at hand...
[/off topic]
Okey, thanks. As someone who warned about AMC, I would be glad to be wrong. Less scam and more successful businesses are always welcome in the Bitcoinland. |

I purposefully didn't, though that doesn't make it not true.
I've seen that they made some structure changes and the shares aren't as bad as they were before. Still I don't get why people are buying that much now, the awful management at the start of the shares made me quite wary of them. |

I disagree.
Investing too much leads will lead you to be too emotionally involved.
Some bad rumour about a bitcoin hack or flaw? You will not be able to sleep that night.
If Bitcoin is a success, you will be rich even with a few Bitcoins, just find the appropiate risk level for you.
The ones who have to struggle to get a few will have to make a tough decision though :/

I'm not sure, but maybe it's moving from one address to an another within one bitcoin-qt wallet?
I remember being able to send transaction within the wallet addresses with 0 confirmations again, when the first one confirmed the second one did too.

so I guess you have to be online for the software to check it is creating a unique wallet address no one else has then I you just go online periodically just to 'sync' up with the network and see your balance. Is that correct?
You only have to be online to check your balance (you can do that with just the address, no need for the private key, e.g. here: http://blockchain.info/) or to spend Bitcoins (private key needed). You don't have to be online to create a new address (it's even more secure to create it offline), the chance of an address collision is extremely slim, even when you create millions after millions of addresses. What happens if you don't go online for a month, for example? If your balance is floating around in cyberpace, is there a timelimit where it can just get lost, swamped in the ever changing, growing data? No time limit at all, the blockchain stores all of them. The second question is how do you back up the private key? I see there is an option to back up the wallet but I cannot see an option for the private key. There are different possible ways: Either make a backup of the wallet.dat file (C:\Users\[Username]\AppData\Roaming\Bitcoin or use file->save wallet) Use a command in the Help->Debug->Console to obtain the private keys Create a new address (e.g. at https://www.bitaddress.org), write down the private key somewhere and import it into bitcoin-qt to use it (also with a command) Important to note about bitcoin-qt:It will send change (e.g. you got a transaction of 0.8 Btc and want to send 0.5 now, you will send all 0.8 and get 0.3 change back) to a new hidden address, after about 100 transactions with change it will create new ones, so they aren't in your backup anymore. I would suggest using the addon Coin Control with bitcoin-qt, it makes this way clearer: https://bitcointalk.org/index.php?topic=144331.0Also remember that whoever has access to your wallet.dat has access to the coins. I assume the wallet balance is the total amount held within each of the wallet addresses correct. How can you delete addresses? You can delete the wallet.dat, the next start it will create new addresses. Once I'm synced on the network, can I 'export' the blockchain to my other computer so I don't have to download it again? yes (Don't copy the wallet.dat and use it on both computers, it works, but it will most likely get messy) |

Every Bitcoin address has a corresponding private key.
Imagine it like a locker for mails, if you have the Bitcoin address you can throw Bitcoins into it, but you need the key to access the Bitcoins.
So to store or receive Bitcoins all you really need is to write down adress + private key.
This is the so called Paper-wallet.
Because all Bitcoins transaction are on the public blockchain, you don't need to be online in order to receive coins, you only need to be online in order to see it.
A wallet is a collection of adresses with their corresponding private keys.
The local software will read the blockchain to see how many coins you have on your adresses and let you interact with them (it has the corresponding keys).
An online wallet is is just like that, but you have to trust the one hosting it.
Remember that everybody who has access to the private keys can use the Bitcoins on that adress.
Don't lose them, don't let anybode else get them.
Paper-Wallet or Cold wallet:
- a very secure way to store Bitcoins, because it's not online. But it's also harder to spend the coins for you
- cold wallet is keeping it in digital form, but offline (e.g. Armory client offers this)
- recommend for bigger Bitcoin sums and long time storage
local wallet software:
- your computer security is your protection of the private keys
- some clients require the full download of the blockchain (e.g. bitcoin-qt), but there are also light versions that read the blockchain in other ways (e.g. Electrum)
online wallet:
- your computer security and the one hosting the service are responsible for the protection fo the keys
- they are usually fast and easy to handle, so they are good for day-to-day purchases
- blockchain.info is a very trusted site (although the customer service may be not that great xD)
- bad for big sums or long term storage

We'll see if this is a dead cat bounce or the end of the panic.
It's a fried cat bounce xD Those go higher with every bounce  |

It's at 4 Btc.
Didn't expect it to go that low, good buying opportunity I guess.

People who fear that can move out of btct.co to direct shares instead of selling the shares, so I guess there is a bit of selling to the current price, but it will not lead to panic selling.

1k Bitcoins = 1000 Bitcoins.  Your choices to cash out are either an exchange platform (like Bitstamp.net, bitcoin.de), a local trade (localbitcoins.com) or a trade on this forum (use escrow - a very trusted person to handle the deal or sell to a very trusted person). |

Ich denke bitcoin.de ist relativ sicher, immerhin gibt es zusätzliche Maßnahmen, die ein Abheben erschweren selbst wenn du nen Trojaner auf dem Rechner hast, welcher dein Passwort klaut.
Wenn die Partnerschaft mit der Bank klappt wie vorgenommen, wird das Geld eventuell sogar versichert.
Das Ding ist halt, daß Du die Kontrolle abgibst. Was bringts Dir, daß kein anderer Deine bitcoins abheben kann, wenn Du es selbst auch nicht kannst, weil der Anbieter den Laden dicht macht, gehackt, oder von der Obrigkeit lahmgelegt wurde? Was es bringt habe ich bereits geschrieben. Für den Fall, dass du dir nen Trojaner einfängst sind deine Bitcoins nicht weg. Ob dies nun wahrscheinlicher ist als die Dinge die bei bitcoin.de schiefgehen können hängt vom User ab. |

Wenn die Partnerschaft mit der Bank klappt wie vorgenommen, wird das Geld eventuell sogar versichert.
Dafür gibt es natürlich die Gefahr, dass bitcoin.de selbst gehackt wird oder der Betreiber die Bitcoins veruntreut.
Für die längere Aufbewahrung ist ein sicher erstelltes Paper Wallet/Cold Wallet immer die beste Lösung.

if the investors get their btc back, it might be bearish if they cash out. if Trendon had an encrypted or hidden wallet, or the BTC are unrecoverable, then having 700,000 BTC vanish / locked out of the blockchain would be a bullish thing.
It's not 700,000 BTC, nearly all of that had been paid out earlier in the scheme, lost in daytrading or sold for cash already. -> this amount will not be locked out the blockchain -> people won't get it back |

There will be 4x as many Litecoins as there are Bitcoins. Why would the ltc markets be equals to the btc one? No reason...
Didn't say equal. Said 1/4th. And why? There will be 4x as many Litecoins as there are Bitcoins. An value of 1/4 Btc means equal in market cap to Bitcoin as there are 4 times more Litecoins. Just as 8*1/4 = 2 and 2*1 = 2 Hint: It will not happen. |

seems so far the general consensus is for me to not tell them to take it down then haha. just trying to think of how the typical person would see it. there aint exactly that many geeky cheerleaders around i suppose if they get anything from it though its only going to benefit the kids anyway. new equipment and better camps etc. not heard of this seans outpost. i vaguely remember hearing about bitcoin 100 though. will have a quick search for them now Well, obviously. If we as Bitcoin supporters start saying "hey, better take it off, most people think Bitcoin is all about drugs" that wouldn't really be good, would it? Who is gonna defend Bitcoin then? And honestly, I don't think Bitcoin is that much about silkroad anymore. |

There are already some bigger charities like the EFF that accept Bitcoin.
I think it's great if more charities start to accept Bitcoin. and will help getting rid of that silkroad image.
From the charity point of view, some donators may think it's tanished, but they may also find new donators.
But Bitcoin is a good new method to donate money, so I think charities would gain from an higher adoption rate of Bitcoin.
