There was not AML or any verification for accounts, so it was super easy to deposit and withdraw both btc and fiat.
In fact, in 2011 I had several accounts on Mt.Gox under different pseudonyms. Later on, they forced me to merge all my accounts into a single account when they started requiring linking an SSN or EIN to all US accounts.

It was easy to buy small amounts on Gox without going through AML/KYC back then. I think the limit for unverified accounts was around $1000 USD/day.

Firstly I have no interest in getting a loan!

I like to scan through the site and have been reading lots of topics of people offering loans demanding 120% collateral, while it is up to the lender to create the terms it just seems to be a risk free way to lend - I am of the understanding that it is the lender who should take the risk, hence why charging interest.

Just my (worthless) opinion.

 Smiley
120% collateral does not make sense, unless it is in the form of highly illiquid assets.

On the topic of defeating keyloggers, I have a text file containing bits of my passphrase mixed amongst random text. When I want to enter the passphrase, I open the text file and copy & paste using the mouse the relevant pieces into the password field.

I know how most key loggers work, and most do not capture the clipboard contents.

Just switch to a 208V or 220V circuit, 120V circuits are a stupid idea anyway.
Unfortunately this is not a financially feasible option at my location. The setup costs associated with switching from 120V to 208V plus the cost of new 208V PDUs is simply not worth it for the extra efficiency for a setup that would run for under a year.

I might have mentioned this before but I go around looking for pre-wired cabinets abandoned by companies that go out of business and I just lease the current configuration for a discounted rate.

Anyway even at 120V I believe the SP30 will perform adequately.

You should at least forward the p2pool port.  That'll get you more connections and make you more likely to win the share race.  Same for the Bitcoin port.  But technically you don't need to.

Ok, can you explain a little more the bold part?  Not sure I follow why letting other connections in helps.

I would have thought that the server running bitcoind would be just pulling down shares and feeding them to my miners, then putting them back up when solved to whatever peer it connected to get them from in the first place.

I think he means that there is a better chance that your p2pool shares do not get orphaned if more nodes are notified the moment you find your shares. It is a known fact that a p2pool node with poor connectivity to other p2pool nodes would end up having more orphaned shares, and you don't get credit for them. Forwarding your p2pool port means that you have total connectivity from both outgoing as well as incoming connections. If you don't port forward then you don't have incoming connections and have to rely solely on your outgoing connections to broadcast your shares.

Can one SP30 be made to run off a single 120V/20A circuit?

This is a DC circuit with wiring good for 30A+ and a commercial grade PDU, so I don't intend to de-rate to 80%.
I would not recommend it, as the internal PSUs are not going to be able to deliver the full 2.5kW to the asics.
You would have your hashrate reduced by ~10%
You mean it will trip the breaker? Well I am paying a flat rate for the 20 Amp circuits so I guess I would have to under-clock the SP30.  Or maybe use 2 circuits and somehow find some other smaller hardware to use up the extra amps (probably S3s).

You could also use a hot glue gun and put a drop of glue into the hole of the buzzer. You'd be amazed at how quiet it becomes.

It is non-permanent and you can pull the glue off when you want the sound again.

How many of you still use Dell Computers?  
I use cheapo Dell PowerEdge R210 servers to manage and control my mining farm - one R210 per cabinet. Time to buy more...

1053  Bitcoin / Bitcoin Discussion / Re: If we want Bitcoin to go mainstream, we'd better start doing stuff like this. on: July 15, 2014, 11:46:12 PM
Sponsoring targets the public. But building Bitcoin acceptance into payments also has to come from the supplier.  With companies like Expedia now accepting Bitcoin the the Travel Industry should be taking note. Certainly an industry that moves a lot of money around internationally.
I try to go out of my way to spend bitcoins on suppliers that accept them. I will try to spend around $10K worth of BTC on Expedia this year on a well earned vacation. I've spent thousands on Tiger Direct and Overstock on stuff that I don't really need (but that I nevertheless like). I think that this is the best way to reward and encourage companies to take the plunge. I don't think we are ready for big ticket sponsoring yet at this stage.

The intersection of what "money" is plus the tech, is major ovelaod for a lot of people.

Hey, once in a while the advantage does NOT go to smooth talking wheelers and dealers who understand finance. That's fair to me.

Everything we ask for is required by law. We do not share or sell your personal information with 3rd parties. If your get really concerned can always drive to the office and pop in to check us out Smiley
Do you have a SAS70 or SSAE16 report that you can make available?
1056  Bitcoin / Legal / Re: Received Mail from Japan Court Regarding MTGOX on: July 13, 2014, 10:40:48 AM
I just got the letter even though the last time I traded there was in 2012 and my cash and BTC balances were close to 0.

It's pretty annoying that my private information is being released to an ever widening circle of agencies even though I no longer have any interest in Mt. Gox.
1057  Bitcoin / Bitcoin Discussion / Re: Ethical price to sell BTCs for cash on: July 13, 2014, 09:30:43 AM
Whatever the market will bear?

Also, you need to consider whether you are providing liquidity, taking liquidity or making a one-off deal with your trading partner. If you are providing liquidity (which I assume to be the case) charging a 5 - 10% premium seems to be the acceptable practice.

There is a cost associated with accepting large amounts of cash. I had to invest in a currency counter to count the cash and detect fake bills, and I've gotten a number of fake $20 bills.

Once Bill Gates said "640K ought to be enough for anybody"
Probably urban legend that Bill Gates ever said that. I was in a Q&A session with Bill Gates back in 1997 (when he was still active in Microsoft) and I asked him why he made that comment. His response was the he didn't remember ever making that comment. Could he have made that comment? Possibly, but being the technophile that he was he considered it very unlikely. And I tend to believe him.
1059  Bitcoin / Bitcoin Discussion / Re: Why Bitcoin Addresses Need to Go on: July 11, 2014, 10:49:26 AM
If you have "a" Bitcoin address, then you are doing it wrong. The recommended way to operate is to create a separate address for use in each incoming transaction. This increases your potential anonymity (or pseudonymity if you prefer), and also adds security by allowing you to spend a portion of your holdings without exposing your public key.
And you are doing it really wrong if you want that ONE Bitcoin address to be linked to you identity via an easy to remember moniker.
This is not necessarily true if for example you are a street vendor that has a lot of repeat customers every day (for example a hot dog stand) as the customers could simply send the bitcoin to the same address every day while the vender is preparing the hotdog and could see that the TX has been propagated by the network prior to giving his customer his food. The vendor could use bitcoinfog for example to move his receipts to another address that he controls so he can pay bills, and otherwise spend his bitcoin with anonymity.

Another example of when it would be good for an entity to use only one bitcoin address would be an entity that accepts donations, for example wiki leaks, the red cross, a church or other charitable cause. This would allow donors to see exactly how their donations are being used.
True, the donation scenario is a valid reason for having a single public and well known address.

However, I don't really buy the hot dog stand  example. If I were a street vendor and gave the same address to all my customers who pay (slightly) in advance, then how would I know who is paying me unless I force them to pay from the same sending address each time? I would instead be giving out a unique address to each regular customer. That way I'd know who is coming in the next few minutes when their transaction appears. For non-regulars a QR code stuck to the side of the cart should suffice. Customers can still send in advance to the QR code, but I won't really know who they are until the arrive and show me their Tx.
