I noticed a couple of hours ago that there's some selling order of 11000 BTCs lying at $15.75 price on Mt.Gox. However some time later the selling quantity at that price had reduced to only 300 while all of the transaction price in the period were lower than that. Obviously, the big player had changed his mind and cancelled his selling order.   

去年底我在Casasius官网上买了两个1BTC面值的实物比特币，花了3.40BTC。30日已发货，估计这个月中旬前能寄到。

我的问题很多，因为实在不懂。

1）实物比特币如果兑现（兑现的英文叫redeem吗？）以后，是不是就没有比特币价值了？如果这样，是否还是不兑现好呢？我是用于收藏的目的。

2）如果不兑现它，硬币中可供兑换的信息能保存多长时间呢？3年？5年？

3）如果我想立即兑现，该怎么做呢？

Needless to say, my offline Armory newly installed on a laptop is empty now and contains no money in it, but in the online Armory installed on my desktop (working together with the bitcoin-qt) there's some money because I've just sent them into it from my another bitcoin wallet.

Now I want to transfer the money in the online Armory to the offline laptop, (may need a USB flash stick again?) but the problem is that I don't know how to do it. (May be I'm a damned fool!)

Anybody can render me help? I need actual steps need to be done one by one.

The first person having given useful tips here shall get 0.5 BTC as reward, but not until I can solve the problem of course - no cure, no pay.

No kidding.

There is a term called Deterministic Wallet in the Armory software. I checked some English-Chinese dictionaries but got no answer yet. Who can give me an explanation for this? Thanks.

我的一个旧笔记本电脑装的是Win XP系统，我在上面装了 Armory Bitcoin Wallet Management ，想作为 Offline Wallet 使用。Armory 在旧笔记本上可以正常打开和使用，但当我在新的一台台式机上（Windows 7 的64位系统）再装了同样的这个程序后，就一直打不开，每次总是跳出来这个提示，使人很摸不着头脑，捣鼓了很长时间都没法解决，见图。大家有遇到这个情况的吗？怎样解决呢？谢谢！

1）纸钱包和头脑钱包到底是什么？有什么作用和特点？

2）使用纸钱包和头脑钱包有什么好处呢？不用又有什么不好呢？

3）怎样创建、验证、使用纸钱包和头脑钱包？

4）操作时有什么注意事项啊？

以上问题我前几天曾在英文板块发帖，

https://bitcointalk.org/index.php?topic=130503.0

得到的回答太复杂，搞不懂。因为的英文理解能力还是不行，此外我还不是一个 IT geek.

I'm not a native English speaker and have limited ability of understanding English text. Whoever has taught me the complete knowledge of how to make the memory wallet and paper wallet (for private keys) and reuse them later on, I'll pay 1 BTC to his address within 24 hours. Need detailed methods step by step, no kidding, thanks.  The would be teacher, please send your info (should include necessary web addresses and pictures etc.) to my email: goldlyre@sina.com , or else, you just paste it here if you don't mind. After you have sent the info, please let me know.

My Client says that the 210934 blocks already downloaded was from 54 minetes ago. Why? Is this normal? Thanks.

It seems most probably to my finger's bone that Bitcoin may break its all time high of $31 in 2013, but don't know in which quarter. Any input and vote shall be greatly appreciated.

I just cannot figure out how to make a brianwallet with a phrase. Anybody provide me with a simple procedure or just a clue? Thanks!

[to da moon]

I'm a veteran silver stacker and a newbie bitcoin speculator. What I'm concerning most now is that in the near or intermediary period which one shall go to da moon first? Siver or bitcoin?
FYI: my DCA of bitcoin is only a little bit under the present day price.

I'm a newcomer and it's my first post here.

I'm a newbie in this BTC thing, and till now I've put 1/20th of my disposable money (for investment purpose) in Bitcoin. To be exact, I bought them directly from a BTC exchange - BtcChina, instead of mining hard all day long with the sophisticated equipments. Yes, your guessing is right, I'm a Chinese people buying BTC with the local currency CNY.

My question now is that how many % of your disposable money have you already in BTC? Is 1/20th too small? thanks.

如两个素不相识的人在网上达成了一笔交易的意向，即A用Bitcoin购买B的某个物品或服务（包括虚拟物，如：书稿、曲谱、信息等），怎样才能克服相互信任的问题呢？

具体是：

1）如买家先付款，卖家不发货怎么办？

2）如卖家先发货，买家不给钱（Bitcoin）怎么办？

3）如上面两条都没问题，钱也付了，货也发了，但买家对质量不满意，要求退货怎么办？

4）可以通过网络传输的虚拟品，如何退货呢？
