Rate this security setup for a wallet I rarely plan to withdraw from:

Encrypted multibit wallets with ample unused additional addresses running on my laptop. (very strong password ~15 characters, mix of upper/lower characters, numbers, no words)
Backed up to Dropbox to protect against a local failure.
Saved to several USB drives, micro SD cards, paper wallets, CDs, all encrypted as AES256 compressed files in addition to wallet encryption so people don't know media even contains bitcoins.
Several micro SD cards, CDs and paper wallets sent to friends and family members across the US for safe-keeping. They don't know the passwords.

Protection against:
[X] local hard drive failure, accidental deletion
[X] dropbox failure
[X] EMP attack
[X] destruction/search & seizure of my residence
[X] localized mayhem
[X] jealous friends spending Bitcoin
[X] laptop thief, jealous friends, Feds transferring bitcoins, dropbox hacker getting wallet access
[X] basically all dictionary attacks and even a botnet brute forcing my password
[  ] rusty pipe attack (being beaten with a pipe until I disclose the password/location of wallet)
[  ] memory loss
[  ] destruction of dropbox, my computer and each and every backup

Is this decent security for a wallet I'll be holding ~$20-100k+ in?

Looking to sell my 60 GH/s single currently in hand in Virginia. Includes overnight shipping. Asking 50 BTC.

I've posted pictures in another thread when I was optimizing the performance. Case is currently off and can be shipped either on or off.

We run an ecommerce business that currently runs on the OsCommerce platform and accepts credit/debit cards through Authorize.net. We'd like to integrate some API (or any API that fulfills our functionality) with our site such that customers can choose between paying by credit card or by Bitcoin.

Service must:
Allow for both Authorize.net and Bitcoin functionality
Convert USD prices to bitcoins at checkout using current USD/BTC conversion rate from bitstamp/mt gox
Provide instructions, current status and confirmation to customers when Bitcoins are received
Automatically send bitcoins to a specified wallet when a threshold is reached (or every transaction)

Payments for your time will be made in USD through ODesk.com. Please let me know your hourly rates and estimated completion time or total cost for the entire project.

I just got an invite for Google Wallet's send to friends feature, which lets you send money to friends easily with Gmail using free to low-fee options. Very handy and convenient for paying someone back. It's presently very exclusive and available to only a limited number of people.

If you receive money with it, you automatically gain the ability to send cash to your friends, who will then be able to send money to you.

Pay me 0.03 BTC and PM me your Gmail address and bitcoin address. I'll send you a shiny penny (YOURS TO KEEP LUCKY YOU), letting you use the Google Wallet feature to send to friends with Gmail.

US-based Gmail accounts will only work.

If you have questions, look at the Google wallet site.

I'm trying to tweak my BFL Labs 60 GH/s ASIC single and am having a god-awful time getting any documentation or facts straight on it. I am a monkey-brained stupid person and need your help. For whatever reason, I cannot register on Butterfly Labs forums.

PRESENT: Running at an average 59 GH/s over an often-on AC vent at ~50-54 degrees C (61-63 C with the AC  off).

I feel like this is probably a pretty decent chip considering the range I've seen other users reporting and feel like it could get at least a 10% more through some sort of overclocking.

Questions:

Does this ASIC 60 GH/s single use the "singles" firmware listed on www.butterflylabs.com/drivers or the BitForce SC firmware https://forums.butterflylabs.com/announcements/3282-bitforce-sc-firmware-version-1-2-5-a.html or something else?

What firmware version did these 60 GH/s units ship with?

When I run Easyminer v1.1.20130703.02.40, I cannot autotune the unit. Right clicking in Easyminer to autotune here per the instructions here  https://bitcointalk.org/index.php?topic=90426.0;all does not show a dropdown menu. Is the Autotune only for other units?  My unit reports the incorrect GH/s to Easyminer- does it need a firmware upgrade to function?

Can these Single's firmware be upgraded like the Jalapenos with an Atmel AVR Dragon? Will this produce a similar 30-50% increase in performance as seen with the Jalapenos?

Is there any other method of improving performance I should try?

Looking to build my first rig. Total cost is not critical, Mhash/hardware cost is. I only pay 1/3rd of electricity and it's a bit cheaper than average, so Mhash/J isn't nearly as critical. I'd like to start with a single rig. I'm looking at sticking a ton of 5770s on a single board. This is probably stupid, which you can all inform me of. I configured the following at Newegg:



Will 5 5770s that close fit into the board and not overheat in an open air situation? This would be in a basement, where it gets probably no hotter than 72 F.

Is the power supply ok?

Are there any configuration issues I'm missing? Is there a more cost effective card/config available somewhere that's actually in stock?

If you're lucky enough to live in an area with deregulated electric providers, you definitely should take a look at switching to someone's who's cheaper considering the electric costs of running a bunch of rigs. I'm in Philadelphia, which recently deregulated. I just switched from the default provider PECO to the cheapest provider I could find, Ambit Energy. My base price per kWh dropped from 10.78 cents to 8.4 cents and eliminated the surcharges PECO charged about 500 kWh/month, which will save me 25%+ a month when you throw in taxes and PECO specific surcharges. I really encourage you to take a look at Ambit or any other deregulated provider. Ambit serves Pennsylvania, Texas, Illinois, New York and Maryland- not sure if their rates are as competitive elsewhere, but definitely worth a look.

I don't work for Ambit energy, but I am a customer and do get travel rewards if enough people sign up under my account. So, shameless plug, if you do decide to go with Ambit, please sign up through my link:

Everyone seems to be immediately focused on the recent Mt Gox crash and the need for enhanced trade security and are designing new exchanges. What about the bigger picture? When Bitcoin gains traction as a real currency, the only place that could provide the security and resources for such a large volume of trades of such value would be forex, and indeed, the acceptance of Bitcoin as a currency on forex would cement its legitimacy and speed its global adoption. Does anyone know what it would take to be listed on such an exchange?

In light of the recent hackings and considering the value of sums being held in exchange accounts, it's obvious that exchanges need to start offering increased security measures to their users. Though no feature can ever make a partially open system completely secure, many measures can reduce the risk of accounts being compromised or damage done without significantly impacting user experience. I propose that the following options be made available to users, who can activate them if they wish. (Deactivation, obviously, would require a few extra hurdles). Not every feature is right for every user, but that's the beauty of choice.

1. Locking accounts to one withdrawal bitcoin address/limit withdrawal address changes: Users can lock an account to a single withdrawal address. Bitcoins can then only be withdrawn to that wallet. I think this would help mitigate damage done to a compromised account. If the hacker can only withdraw bitcoins to the users account, it's no help unless the wallet is also compromised. If a user wishes to change their address, a confirmation link would be emailed/texted/phoned to them and a 72 hour waiting period could apply. Also only the last 4 characters of an address could be shown, to help protect the user's identity.

2. Locking non-bitcoin currency withdrawal options. Same as above, except for Dwolla/Bank/other accounts.

3. Requiring email confirmation of especially large withdrawals. Confirmation by text/email/phone and/or a waiting period could be set by the user for all withdrawals over X amount.

4. A log of IP addresses which have accessed the account in the last week. Like the gmail feature. Useful for determining if a hacker has accessed the account.

5. A user imposed limit on the number of trades per day. If a hacker did compromise your account and found he couldn't withdraw money to his own accounts he could still be a real dick and constantly buy and sell your assets until they all got eaten up as exchange fees. Some users typically buy and hold they could decide to limit their account to say, 5 trades per day.

I think these options would significantly cut down on stolen exchange funds and most would be very easy to implement. Obviously more elaborate and extensive hacking could circumvent these measures, but I think they'd be a sufficient deterrent.
