There are several additional methods for cashing out from bitcoin to PayPal:

and Bitcoin Nordic

I see that Amazon Payments is currently on the site.  Do you still offer this cash out method?

Also, updated the Wiki page:

A transaction that later ended up being an invalid double spend would still show in the client as 0/unconfirmed.

What client are you using? 

Exactly.  I'ld switch to the assumption that my system was compromised unless I could prove otherwise.  That usually would mean a reinstall and proper security.

I'ld like to see some measures made for those whose account value is too small to justify the cost of a Yubikey.  Like offering to have a separate password for doing a withdrawal, or the ability to set a grace period on all BTC or redeemable code withdrawals (e.g., an e-mail gets sent out, and the withdraw can be cancelled up to NN hour hours before the BTC gets sent or the code gets created.)

There is a thread you might want to take a look at.  It is specifically for those with MTGUSD or BTCs looking to trade for Dwolla USDs:

But in no jurisdictions yet is there a legal entity for a "project".  Kickstarter has projects, but no equity so the funds to the project on Kickstart are not "investments" but instead are donations (or pre-sales, in most instances).

So currently these "shares" sold on GBLSE have no legal claim against the profits from the project nor would they have any claim against any assets purchased from either those profits or from the proceeds of the IPO.

Think of "investments" in any of the current GLBSE assets as gentleman's agreements backed by reputation.  (Well, I've seen loans and bonds listed as assets, so maybe those would be the exception where it is a legal contract which could be enforced through the legal system.)

There's no reason a GLBSE asset couldn't truly be a chartered corporation or LLC though (except for how offering equity to the public in this manner is something that is illegal in certain jurisdictions).  There might be tax havens like Anguilla or Cyprus that don't have restrictions against offering equity to the public (unaccredited investors).   Iceland is looking at the concept of a VLLC which presumably would be owned by shareholders.

The reason this entity definition might be relevant has to do with the ability to claim capital gains instead of having to declare proceeds from selling shares as regular income.  Listing an asset on GLBSE as a corporation or LLC entity would probably satisfy the definition of being an equity, and thus long term investment gains would enjoy the benefit of a lower tax rate as being capital gains.  Additionally, with a corporation or LLC there is civil and crimiinal code that limits actions the issuer might consider.

Some pools don't payout until 120 confirmations.   The ones that do earlier are fronting the bitcoins themselves.

This 120 confirmations is part of the Bitcoin protocol:

 [Edit: Oh ... $3,200  to break the lease.  I first read that as $320.    Ya, man, if you are paying for the space regardless, put those free watt hours to work!  Are you sure you can't negotiate some deal to get out for a lower amount?]

A 5 Ghash/s operation will generate a little over $400 per month at the current difficulty and exchange rate:

There will need to be some method that removes the heat for a 5 Ghash/s in an office area.

Also, you are assuming the landlord won't notice the $250 increase in the electric bill and that using the space for this purpose is not a violation of the lease agreement (sometimes they prohibit data processing gear or have caps on electric use).

If you had no restrictions on how much electricity you use and can easily vent then this could be doable, but then what do you do after the 8 months?

There might be a mining operator in your area that is looking to expand but is out of either physical space or electrical capacity who might be interested in subletting your space, but then for a period of just months, that's probably a deal killer.  [Update: But after noticing that you are describing paying the full rental amount regardless of whether you stay or not, ... this is now probably something  to consider.]

Depends on a few factors.

Firstly, what is your cost of electricity?

Huh?  Get-Bitcoin is U.S.

CampBX and BitFloor are two exchanges that will send funds as ACH direct deposit.   CampBX and Get-Bitcoin will both send out a check.  All these are U.S. companies.  

Withdrawing for cash in the mail, that could be risky because should the envelope never make it you have no recourse, unless the seller offers some type of protection.  Here's one seller that offers this BTC to cash (via mail) service:

Here's a guide with the various options:
 - http://en.bitcoin.it/wiki/Selling_bitcoins

If you don't have a problem with giving Dwolla your ID, then withdrawing to Dwolla is pretty much free of any risk.   The problem is that the leading exchange, Mt. Gox, is having severe problems meeting the demand for Dwolla withdrawals so that method will take six days (per their last statement on it) before they send the funds to your Dwolla account.

There are a couple other exchanges that do Dwolla, Intersango and CampBX being two of them.  The problem with selling BTCs at these exchanges is that the exchange rate is lower (as there  are more BTC funds heading to those exchanges than there are USDs).  Arbitrage would normally bring these exchanges closer together but getting funds into Dwolla takes some amount of time and a couple percent gain on the transaction is just marginally enough for the arbitrageurs.

But if you are comparing the final proceeds of a trade at an exchange that trades 5% below spot but you can withdraw to Dwolla versus the final proceeds for those same BTCs after requesting cash in the mail, the amount you end up with, in-hand when all is said and done, is probably going to be about the same amount and will take about the same amount of time.

Withdrawing for cash in the mail now, that could be risky because should the envelope never make it you have no recourse, unless the seller offers some type of protection.  Here's one seller that offers this BTC to cash (via mail) service:

I guess the question I had was, let's say the item is mailed with Delivery Confirmation request, but the item is never delivered?   Are there any guarantees?

 - http://en.bitcoin.it/wiki/Trade#Connectivity

Can you explain how this futures trading would operate?

So these are futures and not options, right?  
But we are not actually going to pay the final delivery amount, and are only speculating on what the future contract will be priced at the point the contract settles for delivery?  What leverage will there be?  (e.g., at 10:1 leverage for instance, my 1 BTC at a BTC/USD of $5.18 would buy me a future contract valued somewhere in the $51.80 range?  Would I be forced out if the price of the commodity drops in value below certain threshold?

As far as which commodities, the BTC/USD and BTC/EUR already have an efficient mechanism, thanks to arbitrage.  About the only thing you'ld be unique in offering is leverage for BTC/EUR speculation.

But the WTI and/or Brent futures are two where there is no easy way currently for the small investor to acquire a small position.  Consider the typical commuter who pays several hundred dollars a month in gas.  The per-transaction trading fees are too high to make it worth it for the commuter to hedge against future price increases by buying shares in an ETF or other instrument in equities markets.  But if a low cost transaction using bitcoins is possible, then there are a lot of people that might start buying futures who previously (like myself) normally wouldn't.

As far as Gold, or index futures, those all could become large for this type of trading as well.  For instance, those in countries without a decent equities market locally might find the ability to easily buy S&P futures useful.  They generally aren't the ones with bitcoins though.  So probably the next most useful future to offer would be the European indexes futures, making it more easy to acquire a position in that market by those in the U.S. perhaps.

Ya, eBay would boot them for getting a low seller score by its customers (long delay to receive after making payment).

But you are describing sending the change back to the address that the merchant now has the private key for.  For a digital currency that can be used anonymously, that's financial suicide.  If you only used it with a single merchant, then if a later transaction spend goes through you might have an inkling as to who might be responsible, as it was either you or the merchant (presuming you kept your card protected from view by anyone else).  

But as soon as you use a second merchant, now either can claim innocence and you would have no inkling as to which was more likely to have been the thief.

This really wouldn't work -- not even for church donations.

The closest might be what cbeast suggests here:



 - http://bitcointalk.org/index.php?topic=74978.msg831067#msg831067

With that, there is the risk that the merchant doesn't really send you your change, but given a receipt and the blockchain you would have a convincing argument that there was a problem.  In that approach, the change goes to a new address that the merchant never saw.  This isn't anywhere near as convenient as the more typical mobile wallet to merchant POS system that we will soon see more widely used, but it would be an acceptable method, as trust by the consumer only needs to be extended for a relatively short amount of time (before a problem is noticed).

In reading Adrianne Jeffries (who covers Bitcoin pretty regularly)'s latest ... she and fellow journalists point out how the Venture Capital funding industry is overwhelmingly male.

Here's a 70-page slideshow.  Pick any slide, they almost almost all look identical:

 - http://betabeat.com/2012/05/female-partners-venture-capital-firms-fem-kleiner-perkins/

Bitcoin has to some degree the same level of "male-ness", in nearly every aspect.  Is there a single woman in the list of contributors at Bitcoin.org?
 - http://bitcoin.org/about.html   (And no, genjix offering to go on a date in drag doesn't count: http://bitcointalk.org/index.php?topic=2604.0 )

Is there a single asset on GLBSE where a woman is the issuer?

Are there any bitcoin startups led by a woman (err., ... I guess there is, a stripper for bitcoins service: http://bitcointalk.org/index.php?topic=75114.0 )

There is progress.  Adrianne is ... a woman, interested in Bitcoin ever since starting to cover it just over a year ago.    Morgan E. Peck is a science and tech writer and she just wrote the Bitcoin article in IEEE Spectrum:
 - http://spectrum.ieee.org/computing/software/bitcoin-the-cryptoanarchists-answer-to-cash

There is a low barrier to entry for GLBSE making it even more valuable for those looking to raise funds for a business and have been frustrated with conventional methods -- a situation that many woman-owned businesses find themselves in.

But maybe I'm not familiar enough with all the asset issues.  Are there any assets on GLBSE where a woman is the issuer?

Awesome!
