I guess it depends where you are - in China every 50 or 100 RMB note (rough equivalent to 10 and 20 dollar bills) is generally checked (if not by a device then by close visual inspection) as there are so many fakes going around.

When selling items of low value 1 confirmation should be fine (you only really need to wait multiple confirmations for very large amounts).

QR codes aren't really a big bother when you consider the security of being 100% air-gaped. Also if you happen to have an old laptop hanging around then you have the most secure solution available at pretty much zero cost.

So if BTC went to $10,000 then you would still buy a Trezor for 1 BTC?

(guess you'd be about the only person that would value the device so much)

I'd hope quite a bit for that outlay - but maybe you bought the coins for $1 each so really the point is not about what it cost you but the fact that right now a Trezor is worth more than most smart phones - yet it has no camera nor a big screen or anything else that should make it worth so much money and if anyone saw it they would know you have BTC (which as I said before you could not tell from just having another smart phone).

They should never have priced their product in BTC and unfortunately have pushed themselves into a bad spot now.

It is pretty simple to do offline tx's with an old laptop as I do using the CIYAM Safe (which is actually *safer* because it does txs entirely "air-gapped" via QR codes - something their device cannot do).

I predict that software like the CIYAM Safe operating on a standard smartphone that is internet disabled will be much more successful than the the Trezor device.

When it comes down to someone seeing you're stuff - a Trezor is an obvious device that says you have *lots of BTC* whereas an extra smart phone won't attract any attention at all.

Yes of course you can - it's called "signrawtransaction" (I use it with the CIYAM Safe which is a 100% air-gapped offline tx signing system).

Hi kekky,

You can apparently buy all sorts of illegal things on Taobao - I guess that is simply because of the power of the owners.

That doesn't make any comparison between QQ coins and Bitcoins (due to Taobao) either correct or sensible - the fact that you can buy illegal things on Taobao does not put QQ coins and BTC on a par - it just shows how things work in China.

In the article you linked to I see this:


So although it might be happening it is not according to the rules (and likely will be stomped on) - again this is not the same situation as BTC.

This is not correct - you *can* sell your BTC for RMB on btcchina and other exchanges (they do now insist on ID which is no different to other major exchanges).

You *cannot* sell QQ coins for RMB (via any equivalent to an exchange) so that is a *huge* difference.

The latest statements basically restrict BTC to being more like a "stock" (which you can speculate on) than to being the equivalent of QQ coins (which function more like "reward points" that you can exchange for "virtual goods").

Ouch - a very hard way to learn - if you have any idea what your old password was then you might have some luck with a wallet recovery service.

In the meantime get some sleep and try your best to relax (it's much harder to be of much help to yourself when you are overly tired).

Why would you expect a wallet encrypted with an old passphrase to work with a new one?

Sounds like you are just not using the correct (meaning older) passphrase for your backed up wallet.

It just takes some time (generally not more than 10 minutes).

As far as I am aware there is no problem at all cashing out via Tenpay now (Alipay is no longer an option though from what I gather).

Yup - a good chance to make money now.

I think you could be on the money - if btcchina is still working fine next week then I think the price will be back up to where it was.

Just checked with my wife - basically it is not clear from the Chinese (and most likely this is on purpose).

My wife has been translating some of it to me and it doesn't sound very good (although I'd agree what we are seeing is some "panic" selling)..

It seems for individuals to buy or sell Bitcoins is fine but it's beginning to look like businesses will not be able to do business using BTC in China with the biggest concern for Chinese investors probably being whether btcchina could be forced to cease business (nothing was specifically stated about that or any other Chinese exchange though).

I think you are at the stage of needing to grep through the source to work out where that error comes from.

Possibly you might be looking at a corrupted wallet but you might want to check it out a little further before giving up.

You got it!

Best idea is just to create a new address any time that you are going to accept funds.

The bitcoin-qt wallet will automatically send "change" to new addresses so unless the client you're using doesn't do the same then you shouldn't have any other troubles.

You can also just send your entire wallet balance (minus tx fee) to a new address that you create if you are at all worried about previous addresses.
