Is the network hash rate on bitcoincharts.com is accurate or statistically estimated? It's fluctuated from 7Thps to 4.7Thps, which is a huge drop.
Why would 33% of the network switch off mining?

I'd pay good BTC for a client with these features. Someone should set up a company to do this stuff.

I'm getting the same "Invalid bitcoin address" error message today from mtgox for a small withdrawl (<10 BTC). Is there any known issues with MtGox withdrawls? I've also tried typing out the address.
I'm using Win7 64bit with Firefox + Chrome.

800BTC for a laptop! Nice! We have a new top for the BTC Purchase leaderboard.

If you want some property, I have a 3-bed house I'm trying to sell. Will part with it for 21,000 BTC. It's in Leicestershire in the UK, very nice part of the countryside. Any takers?

Watch out for scams to steal your bitcoins as you spend/donate it  http://evilpacket.net/  (Is this vulnerability fixed now?)

One possible solution :
If the bitcoin client supported a standardized text block containing the address & amount, eg.
BCAddress=12hFuVrSpLaPeTxwGUoPXoTDuhFnDhxRu3,Amount=1.5BTC

then you could have a "Copy to Clipboard" link, paste it in to the bitcoin client, and click Send. Would make BTC easier to spent, as you wouldn't have to write in the amount.

Don't know how secure this is though, maybe someone can write a web script to snoop the clipboard buffer?

Yeah, I've put 1 BTC on the next bitcoin lottery. Gonna get rich quick!

But seriously, without real merchants this is going to be the biggest flop since the Amsterdam Tulip Market 



Ironically, if Bitcoins are to be worth holding long-term, their price will eventually need to stabilize to encourage real trade. Otherwise everyone will hoard their "valuable" coins until it's all too late.

Has anyone bought from Bitcoin Amazon? http://coinbits.com/want-to-buy-something-on-amazon-want-to-pay-with-bitcoins/
or used the Amazon bitcoin-cashback scheme? https://bitcoinbonus.com/content/get-2-or-more-your-purchase-price-back-amazon

Is there a leaderboard of the largest BTC transactions for real-world items?
What's the largest purchase of a real-world item (not money) that you have made in BTC?

Thanks, works now!

There's nothing in the /home/tc directory, it looks like an empty TinyCore installation. Can you double check your upload?
When it boots it says :
"Invalid device specified. Ignoring persistent HOME request!"
...
"piix4_smbus 0000:00:07.0: SMBus base address uninitialized - upgrade BIOS or use force_addr=0xaddr"
Didn't see anything in the boot logs I could find (/var/log/Xorg.0.log), but it looks like /home is set to /mnt/hda3, which is empty?

Thanks for the security advice. If the only security vulnerability is the core, how would I upgrade that? Also, presumably you may find a vulnerability in the linux bitcoin client, so I'd need to keep that upgraded.

Are you still planning to write instructions for others to build their own secure PC? (ie. if they don't trust downloading the .vdi)

Thanks, got the VM running but can't find the Bitcoin app.
Have you done anything to secure it or is this a vanilla TinyCore linux build? I'm not familiar with how to keep a linux PC secure & patched, is there the equivalent of a Windows Automatic Update feature?

Hi Bitcoin community!

I'm looking for a way to store my bitcoins securely. I can store them offline, but if my online PC is compromised I risk them being stolen just as I go to spend them. Does anyone have good instructions on setting up a secure virtual PC for doing bitcoin transactions? Or is the virtual PC only as secure as the host PC?
