First of all all 3 ratings agencies violated the law when that where publicly speculating during the debt-ceiling kabuki theater. The law prohibits them from giving a rating until they have done an analysis. Pretty hard to do an analysis when you don't know what the final legislation is going to be.

Secondly, mortgage backed securities where rated AAA ...how did that where out? Some AAA MBS experienced 80% default rates within 90 days of being given that rating!


Their corporate charters should be revoked.

WERE.  Repeat after me.  WERE.  Not where.


Sorry, I usually don't go anal on people for spelling but I seriously felt like I had gone full retard trying to read your post.

You can't help if you are non-native and using language with idiotic and archaic spelling system...


How well do you expect current goverment to handle this issues with theater we saw last weeks, utter carelessness about country and just thinking thinks would go on like they have...

Not trolling but this thread sparked this idea up. Soon people will have there Bitcoin addresses printed on their body as tattos so they can scan their money when they go to the market. This is the part where the Christians say "OMG THE APOCOLYPTIC CURRENCY HAS AWOKEN!!!". But in reality I'm highly religious so not trying to offend anybody here.

That would have to be a centralized currency, not a decentralized one, like bitcoin, and it's completely off topic to boot.  Wink
Not entirely off-topic, I was trying to give suggestions as what mediums we could safely store addresses(obviously not private keys) but also adding a religious pun to it.

Safety of address isn't realy an issues?

Every used key is know anyway... Also, you need private key to make a payment...

About the safety of addres isn't issues...question. If someone has your private keys someone the jig is up if someone takes it and then asks for you address.
Thats what I was intending to mean about safety anyways.

Hmm, I'm not in to math, but can't you connect public and private key to each other, if you know the limited pool of public-keys(the chain)?

Instead of hackers, i'll worry about arsonists. lol
Also a good point. So you'd at least want multiple copies.

Create keys offline, print them on paper.
Indeed. A possible workflow would be:

1) Preferably on a device without network connection you want to run an application that generates a number of keypairs. The private keys are printed to paper (or some other hyper-secure place), the associated public keys (addresses) are written to an USB stick or digital medium.

2) The bitcoin client on an online device is then used to send BTC to the public keys generated in step (1). It sends a configurable number of BTC per address.

3) When you want to spend the BTC, the private keys can be scanned/retrieved as needed, for the amount you want to take out.

So (1) happens outside the bitcoin client, (2) and (3) happen inside it.


Note for step (3), if you don't use for full amount, remainder must be transfered to new keypair from step (1). Once you have key-pair on device which is connected to net, you can't entirely dismiss possibility of it being compromised.
811  Bitcoin / Bitcoin Discussion / Re: MtGox: The ultimate bitcoin mixer/laundry? on: August 05, 2011, 08:25:41 AM
I've seen a couple separate bitcoin mixer services, but aren't we missing the ultimate one? I'm pretty sure MtGox dosen't send you back the same bitcoins you deposit when you withdraw, so can't one obtain untraceable coins by simply make an anonymous account, depositing and withdrawing the coins? (in randomized amounts of course) It certainly has far more volume than any of the mixer services out there.

There's no guarantee that MtGox doesn't keep a record of where the bitcoins came from and where they went to, and in fact it is in their best interest to keep these records.

So, if I were to steal 100,000 btc from you, and then deposit into mt gox, and then withdraw it to another account, police could probably still get that the coins went into account x and then they went to bitcoin address y. If I then paid for something to be delivered to my home with bitcoin address y, they could contact that seller and find out where I live.

Presumably a mixer would not keep these records.

Why they shouldn't keep records? They should atleast know:
1. From where the coins/money came.
2. Where the coins/money went.
Both connected to account.
For other purpouses also the trades which happened on the account...

If you don't trust your computer abilities enough to make your own securely, get a paper bitcoin wallet from Casascius or someone you do trust to do it right. Encode by hand the private key (see link in my sig) with an unbreakable one-time code. You can then put the encoded private key into emails or whatever. As long as you don't forget your passphrase, you're completely safe.

In five years' time when you want to cash out your now-hopefully-fat wallet, only then does the plaintext private key get near an internet-connected computer.

Adding an other layer is good, if you are absolutely sure you can remember the key for decoding.

Personaly for extreme security I support multiple keys even for this, best with geographicly separated copies.

Create keys offline, print them on paper.

Import one for daily use for phone, keep only the ammount of cash you would normaly keep on person something which loosings isn't a major deal for you, be it equivalent for 50€ or 1000€.

Don't stack all the coins on one address.

One more idea, which need some work. Way to export private-key+bunch of transactions. So you could bring one key active and move BTC from it(burn the key it might be lost at this point), without compromising any part of your entirely off-line wallet. Most secure way would likely be to burn it on CD, and run ones connected to chain on network.

So store on one key, and when you need the BTC move all the BTC from it to other storage and day-to-day use wallet. So, every storage key is used only onces.


Paper or write only media is most secure, USB-sticks can carry infections... Anyway we can't ever get rid off issues on end point devices, but before it can be secured quite fine...

815  Bitcoin / Bitcoin Discussion / Re: Bounty for "Tom Williams"'s capture on: August 05, 2011, 06:15:51 AM
I will commit 10 BTC to the bounty. However, unless a VERY reputable member steps up to escrow the coins for the bounty, I would rather hold them myself.

would you feel better if we had someone reputable like Bruce Wagner hold on to this bounty wallet?

Right now, no one is reputable, including anyone claiming to be Bruce Wagner or the real live Bruce Wagner.

Being a Hero Member is useless too SgtSpike - nothing personal.

I trust exactly 1 person regarding my BitCoin.

You have it much better than I do, I got one less Sad
816  Other / Beginners & Help / Re: Don't use online wallet services. on: August 05, 2011, 05:27:49 AM
Online wallet services are needed for instant transactions, but one should only keep the amount they are using in near future on one.

Main savings should be kept on multiple off-line adresses, with minium of one copy, maybe one on paper, so even if someone gets very very very... very lucky only portition is lost.
Key points of security:
1. Keep the 1000s off-line with certainly safe address.
2. Split it up if possible...
3. Make copies, USB sticks might die on you...

Still, it's Dwolla's problem and if TradeHills post are right they just deleted past records and not mark those reversed or anything like...

819  Bitcoin / Bitcoin Discussion / Re: The Ponzi scheme argument on: July 15, 2011, 05:16:31 PM

So, what you're basically saying is that bitcoins, USD, gold, silver, wheat, salt, rice, beef, pork, etc, are all Ponzi schemes.


This.


Bitcoin is comody now, which might be in future used as currency. Its like collectable goods, minimal real value, but high expectations and thus high price not a Ponzi.

It might very well be a bubble, but not a Ponzi. Ponzi should be used with centralised schemes where early investors are paid by later. Pyramid is bit more complex. As nothing is paid out, it can't be Ponzi.
820  Bitcoin / Bitcoin Discussion / Re: The Ponzi scheme argument on: July 15, 2011, 09:58:16 AM
Ponzi:

A invest money
B invest money
A get's his own and part of B's money back
A invest back
B get his own and part of A's newly invested money
and so on and so on...

Bitcoin isn't Ponzi as the value comes from increase of value of investment. Like any real good, gold, art and collectable. Also this good is "minable" so there is option to produce your own.

Just like gold isn't ponzi...
