I don't think we will see 105 again today. If the posters here are correct that the wall at 111 was eaten rather than pulled - I wasn't here so did not see it - I think then 120 will become support today.
It was eaten. I saw it too |

偶已经看了挺多的资料，不用给我解释什么blockchain 等等。
以下问题针对ASIC 矿机：
我想知道的是，ASIC 矿机除了算Hash，完成工作难度证明，不参与交易块打包吗？
这不是很浪费电能和资源？而且真正的交易计算量也没有放到矿机上算。
还有就是，
如果以后的比特币挖矿产能小，矿机是否能够完成收取手续费的工作？
我知道软件上矿工是能得到收入的。
礦機只負責hash, 你還必需有一台電腦運行bitcoind處理交易. 和hashing相比, 處理交易的運算量微不足道. 如果不想自己運行bitcoind, 可以參與礦池, 其實就是讓別人替你運行bitcoind, 你付點手續費作報酬 |

by the way - btcchina.com is not even reachable from within China without VPN or proxy.
FUD? This is the first time I've ever heard this |
|
|

Is btcchina.com built on phpBB and it's still handling smoother than Gox..lol
No, actually it's pretty bad these days. Last night I traded there with >10minutes lag |

Reasons:
1) Discourages putting in orders ahead of time:
If I am a big seller I can loose my potential to buy if I put in a buy/sell wall ahead of time, because people will outbid me by a couple of cents and I get screwed. It makes much more sense to put up many mini-walls every time a price hits a value. This rewards buyers with bots, and screws over normal users.
2) Encouragement of bots means greater lag since rather than one big order, many small orders are entered. This causes a harmful self-feeding cycle as bots pile in as lag increases and their buy/sell targets are hit, causing yet more lag.
3) Lack of market orders ahead of time increases instability because the buy/sell walls aren't there to support price if, for some reason, the bots cannot access the trading engine. This can happen for a variety of reasons.
4) Means that users with a huge amount of money in their brokerage accounts can put up huge buy/sell walls in an attempt to manipulate price. Along with the previous reasons, it essentially encourages people to put up fake buy/sell walls and discourages people to actually put up real ones.
5) If you are reporting data that is clearly fake, why report it at all? Take away the need for trading bots, take away the potential for fake bid/ask walls to scare noobs into panic/sells. Just don't report market depth, period.
It would be best if a market maker created a bitcoin "dark pool" and didn't report anything other than bid/ask and potentially volume. The market maker would take steps to reduce slippage on his own, potentially coming in to prevent slippage within one order at his own risk if needed, compensating the risk by taking spreads as profit.
It's a free market. Just open a dark pool exchange yourself |

First of all-you just suck if you're the one who gave this a thumbs down.
Anyways, to elaborate,
I keep ALL of my bitcoins physical (maybe I really am paranoid by nature), except about .25BTC in an online hot wallet. I have bills (part of the reason I do like this is because I like designing the bills) of denominations from .1-25BTC. I keep them in a safe place, and when I want to buy something I just redeem it to my hot wallet.
So, I guess my question is basically this: am I a weirdo for doing this, or is there any way reusing keypairs could be dangerous?
Unless you are worrying about quantum computer, reuse keypair is safe as long as you keep the private key safe. BTW, the thumb down is given by yourself |

Question for you:
for Chinese people living in China, what are the methods of funding their newly created accounts in btcchina.com, and how long does it take for the funds to show up?
I assume these transfer methods are available also in the weekend (e.g. right now) because China never sleeps. Correct?
They can use alipay and tenpay (Chinese version of paypal) and wire On weekdays, deposit is usually cleared in hours. It may take longer in the weekend. Thanks. If I read you correctly this means that no fresh money has arrived to btcchina yet. So the price rise in btcchina is due to speculation from existing btcchina users after the CCTV-2 news - same users who dumped yesterday. Things might change tomorrow or Monday when new depositors' money will be available for trading... Not exactly. It depends on the capacity of btcchina. Like gox, they have been "the victim of their own success" in the past month and have seriously delay in processing deposit. By the way, I have just received my tenpay withdrawal today which means they are working on Saturday. EDIT: From their website, I think they are working 7 days per week now. |

嗯。两年后，我开始有实力长期关注比特币相关创业团队了……无论什么事情，都需要足够的耐心等待才行……
和某個交易所有關的嗎? |

联系人John (John K.)就是本版版主，他应该是中国人吧？
他是中国人.但他中文很好..老比特币了. 这贴回的，中国人还有中文不好的？ 他是馬來西亞華人 |

当然可以
关键问题在于
1 你是否有熟悉的官员（我意思是那种无话不谈的 你懂的）
2 他了解这东西吗 BTC 他是否信任你
3 最后他的钱到了国外，存在那里最安全 这肯定是他要考虑的
2. 如果他不懂BTC, 那就只能信任別人; 如果他懂BTC, 他自己也能處理 3. 錢到了國外就容易辦了, 最難的還是越過國境吧. 而且這問題就算是用傳統的洗錢管道也是要考慮的. |

I am interested in seeing their solution for actually withdrawing money from a bitcoin address. I would also like to see and actual product in action instead of an ATM with a bitcoin logo Photoshopped on top of it.
I guess it will be done like this: 1. User enters the desired amount of fiat. 2. ATM returns a BTC address with the required BTC amount 3. User transfers BTC to the address within a few minutes 4. Either the ATM or the user provides a passcode 5. User returns after 1 hour, enters the passcode, collects physical cash User may also do steps 1 to 3 at home and collect physical cash later at the ATM Or the machine can give you the option for an instant transaction by using easywallet or another off-blockchain solution Yes, or green address |

这也是我思考的问题 仅仅手续费吗
手續費的比例會愈來愈高 |
|

BTC的市值还不够大，够大后是可以的
所以BTC有別於一般商品. 一般商品價格愈高, 需求量愈低. 但BTC價格愈高, 則需求愈高, 因為能做到的事情愈多 |

多谢指教，有测keylogger的软件吗？现在被木马弄怕了，什么软件都不敢下。
如果你已經不信任你的電腦, 最好還是重灌系統吧. 更理想的做法是用一台舊電腦, 重灌一個乾淨的系統, 最好是linux, 只用作處理bitcoin之用, 把以前用過的密碼全部改掉, 電郵也是專門處理bitcoin用. 是麻煩一點, 但為了資金安全是值得的. |

我现在用了google authentication, 感觉上确实安全，不知道黑客技术有没有办法。我估计我这次是被钓鱼网页植入了keylogger， 不知道这东西对google authentication有没有效果。
如果是keylogger, 理論上任何方法也沒有幫助. 最好還是注意系統安全吧. |

目前為止, 我聽過所有被盜的, 沒有一個是用了google authentication / yubikey.

Inspired by this: https://bitcointalk.org/index.php?topic=181734.0 , I think we need a better transaction structure. 1. A new script code OP_FEE should be added. Bitcoin sending to OP_FEE is processed as transaction fee. This allow people to specify transaction fee explicitly and human mistakes in handling raw transaction could be avoided. Also, this would allow people to designate fee amount more easily in constructing contracts ( https://en.bitcoin.it/wiki/Contracts) 2. For a transaction with at least one OP_FEE output, total input value must be equal to total output value. Therefore, SIGHASH_WITHINPUTVALUE suggest in https://bitcointalk.org/index.php?topic=181734.0 is no longer needed 3. One signature for all inputs with same script. A lot of block space is wasted by transaction like this: http://blockchain.info/tx/0a509adf741d9071dcc9a1f169df8bd5efb6b006a71c7f2fd19e5a3596f12e3f , as one signature (and public key) is required for each input even they are signing for the same address. The right way should be signing all these inputs with one signature. This will allow people reuse address to collect thousands of outputs, and sweep these outputs with a small size transaction. In long run, this will reduce the stress on block size and also the UTXO size. This will not compromise security as people can always use a new address after the old address is swept. This may compromise anonymity but it is still up to user's choice. 4. Replace SIGHASH_SINGLE with "SIGHASH_MULTIPLE", which allow signing multiple (but not all) outputs. This could be very useful in constructing contracts and colored coin transactions. |
