I was looking at the graphs and I noticed that the volume at CampBX is steadily increasing. Congratulations. Maybe we can start short selling soon Wink

Or take a look at bitmarket.eu. They serve as an escrow for person to person transfers. There are some people there who trade with paypal.
1043  Other / Beginners & Help / Re: Looking to buy 10 bitcoins using paypal at 1:1 on: August 02, 2011, 01:16:57 AM
You most likely won't get that with Paypal. Paypal transactions are reversible, but bitcoin transactions are not. Since you do not have any reputation here in the forums, it will be hard to find someone here that trusts you. But good luck.

Instant Sell assumes that it would sell by the price which buyers are willing to pay. And it may not be good for you.

Suppose that I want to buy $100 of BTC to spend on Silk Road. I couldn't care less if I am buying at $13.34 or $13.41 because I don't plan to sell them 5 minutes later to earn $0.5. I just want to buy stuff with bitcoins. For someone who wants to buy stuff with bitcoins, these exchanges make you do lots of useless calculations...

The MtGox hashes were mostly salted, the unsalted accounts were dead accounts where nobody has logged in for months. Each salted hash used a unique salt. You would need to generate a unique rainbow table for every single password(salt) in the list. And generating a rainbow table for every single salt in the list, would take just as long as "simply" brute-forcing them from the start. That's what i meant by "it's pointless to create salted rainbow tables"

Yes, but our fellow wewillfightintheshade claims he has such tables Smiley

Unless your password is longer than what he has or the salt is bigger than 128.

Update: We have enabled bit-dust, and now users are able to transact down to a single satoshi.

Elgawwf, can you please check and confirm on behalf of the thread?

Thank you!

Does this also work for withdrawals?

4670 also works with AGP, but you won't get much more than 40Mh

You can tell just from basic discussion on the forum...  it's always in this order as well... 

1 - security
2 - how it works
3 - security
4 - ease of use
5 - security

It's more like:

1 - OpenSource?
     No: Scam/Vírus/Trojan. I will never download it.
     Yes: Let me check the code and I will tell you.

2 - Got reputation on the forum?
      No: Nobody will use your service.
      Yes: Let's wait for feedback from someone respectable

3 - How do you save user's passwords? No salt? No HTTPS?! Are you kidding?!
(.....)


People interested in bitcoins are in general computer geeks with a great interest in security. Now tell me, what happens if you take a bunch of security experts and make them run sites to sell stuff to each other?

It's not really that exciting out there. The real nice people hang around the noob section  Cool

Since this is probably a trojan that steals your wallet, I Googled some Objective-C docs and wrote an open source clone in 45 minutes.

That's mean. You're stealing the idea without any proof that his software is harmful. I know that there are scammers, but there is an open source paranoia in this forum. Open Source is not always good, as you have just demonstrated.

I seriously doubt that this is a trojan. He could have stolen wallets without creating the original logo + avatar. They both look quite nice by the way.
1051  Economy / Trading Discussion / Re: Noob question about price matching on: August 01, 2011, 06:49:55 AM
This is actually a matter of exchange policy.  Almost all exchanges go with the price on the older of the two orders in the match, but you need to check with the exchange to be sure if the exact behavior matters to you.

You should never tell an exchange that you are willing to accept a price that you aren't actually willing to accept.

OK, thanks for the advice. I think that all this trouble could be avoided if there was an "Instant Sell" option that would sell at the best price...
1052  Bitcoin / Bitcoin Discussion / Re: Three New Merchants are now up-and-running with Bit-Pay on: August 01, 2011, 03:37:33 AM
Great. I like the new logo Smiley
1053  Economy / Trading Discussion / Re: Noob question about price matching on: August 01, 2011, 03:24:45 AM
Thank you for the answer. In my case, I just wanted to sell some bitcoins at MtGox, but by the time I filled in all the details, the price shifted a little and my order was pending...

So if I just want to sell, I can put something like $1 and I will get the best price currently on the market, right?
1054  Economy / Trading Discussion / Noob question about price matching on: August 01, 2011, 03:15:32 AM
Suppose that the lowest bid is $14 and I issue an order to sell 1BTC at $10. Do I get $10 or $14? (and the same thing for buying)

The NSA, oh nevermind they already have their own tables.

I'm very interested since it's my job to be interested but the requirement to have a 50TB device just to house the tables required to solve a 16 character password not to mention the CPU/Bandwidth requirements to still process that amount of data against a password is something only the folks with unlimited budgets are able to buy into, as in those folks in DC or just outside it in VA.

It does or should make you wonder how long it would take the NSA to actually crack those 16+ character passwords as you know they surely have their own tables, most likely stored on some form of SSD and able to cluster the attack using multiple systems polling those tables.


But aren't these tables sort of useless? I mean, If a website decides that the salt is: "websitename.com"+128 characters, your 50TB of data is completely worthless. You have to brute force it again...
1056  Bitcoin / Bitcoin Discussion / Re: Want Bitcoin to have a real user/merchant support site? on: July 31, 2011, 07:58:22 AM
Bump because I like this idea and because I just got to 200 rep  Cool

Also, here's the list of websites: http://stackexchange.com/sites

Thx . Is that your real picture? Tongue Your pretty hot...

There is something really strange going on in this board... There's a lot of sexual tension. Maybe it's because of summer? Tongue
1058  Other / Beginners & Help / Re: Security, rainbow tables and other wonderful things. on: July 31, 2011, 06:59:00 AM
Hum... I don't think you will get past the 9th or 10th character... At least in 2011 Tongue But good luck with that. Maybe someone is interested.
1059  Other / Beginners & Help / Re: Security, rainbow tables and other wonderful things. on: July 31, 2011, 03:39:20 AM
I am not a security expert, but isn't salt used to make it impossible to create rainbow tables? Well, not really impossible, but I think rainbow tables with salt take so much space that it becomes unfeasible to create/store them.

Those 6TB correspond to what exactly? How many passwords do you have? I bet that hundreds of years will pass and you will not be even close to the 20 characters + 128 salt.

Flagged as scam/fraud. Everyone else should flag it as well.
