842  Economy / Exchanges / Re: BTER stole my bitcoins!!! Still owes users BTC from the hack! on: August 16, 2016, 05:35:59 PM
Well, that's the risk with exchanges... I'd take that money as a loss. If it comes back, it's an extra.


BTER has been hacked a year ago, and many users lost their Bitcoins. BTER is working fine and they returned minor amount of the owed funds a few weeks after the hack to calm people. Over one year has passed, and they didn't return and more of it - they still owe me 1.7BTC !!!

http://imgur.com/a/7h3sJ

There is no information or news regarding stolen funds nor do they answer any support tickets or emails regarding that. Complete silence...

Anyone have any information? I would stay away from trading at BTER, don't know when you can lose your funds...

well, i was checking out some exchanges to do some tests on trading. BTER was on my list, but now i will skip it. thank you for you post and as you see that result of it is that i will not use this service.

BTER has been known to have some issues for quite some time.

Last time I tried, they didn't work properly on all platforms (I don't recall if I had issues on Windows or Linux...) but I honestly didn't try to make it work as I rely on a separate tool to make the codes.

USB sticks are deemed less safe. There have already been a few discussions about this on the forums, some quick findings: 1, 2, 3, 4

AFAIK only Samsung used a fingerprint scanner on screen and they've already ditched that... But yeah, I kind of get your point Cheesy
You mean on the Galaxy S5?

That would have to be weighed in regarding data randomness obtained in both methods and if the security given by one method tops over the cost saving the other method offers.
I'd say generally, that the retina scan should provide better security however there are obviously important factors that play a role in this. I wonder how secure the iris scanner in the latest Galaxy Note is.

Since it would only be to recover a passphrase, I'm not sure if it would be all that impractical (you would only use it once in a while). We would probably have to build hardware for that tho... Lips are very distinct, and they're also used for investigation in forensics, hence my idea Smiley
Indeed. It is less impractical if rarely used, although I do wonder the implications of this. From what I've gathered, there's only some research in this area.

Correct, it's the S5 that still had in on screen.

I assume the Galaxy Note uses a Secure Enclave-like system and encrypts keys on a separate chip

Furthermore, there are 2^160 bitcoin addresses, 2^63 grains of sand on all the beaches on the Earth, and only 2^33 people on this planet. Using a fingerprint, just like using a brainwallet, significantly reduces the set of possible keys and therefore decreases security. Given that vanitygen on a GTX970 can do 40Mkeys/sec, it would take just over 3 minutes to calculate 8 billion keys; this means your fingerprint based brainwallet will probably be cracked pretty damn fast.

This is something I'm really curious about... What about retina/iris, would it increase the set of possible keys?

so how can we mine the coin .Huh?? then if the website and nothing is working.

is there anywhere else we can download the wallet and mine.Huh

Read the OP

Moto is delisting on C-Cex so withdraw your coins. I suggest to move to Cryptopia and support the market there:

https://www.cryptopia.co.nz/Exchange/?market=MOTO_BTC

Best if we focus on one exchange only, could perfectly be this one.
846  Economy / Exchanges / Re: OKcoin - illegal business/money laundering - Judge rules on: August 15, 2016, 09:52:00 PM

I think the impact won't be that big because we know that volume trading is fake/manipulated. The trader/whale only going to another exchange.
Would be different if they can't pay fine, got hacked or run away with customer money.


despite the fact that everyone knows what's going, markets run on perception and enough stupid people would panic for there to be a hefty fall and more doldrums. the whales depend on the sentiments of the dimwits to take more coins off them.

Yes, this is exactly what I meant Wink
847  Bitcoin / Electrum / Re: cold storage n cross plataform malware on: August 15, 2016, 09:12:06 PM
I don't think having two different distros will enhance your security.

There are solutions beyond usb sticks. Examples are QR Codes and audio transmissions.
848  Bitcoin / Electrum / Re: another noob with LOST BTC on: August 15, 2016, 02:31:51 PM
No way to reverse payments in Bitcoin. I don't think anything else can be done.

has anybody noticed the fact that the motocoin website is listed as domain for sale.Huh??

Yes, for quite some time.

And I guess I've just answered myself, we were delisted from C-cex, so no immunity there.

You should choose the one you like the most and avoid web wallets. Out of those I chose Core because it's the one I prefer, although not the one I use anymore.
851  Economy / Marketplace / Re: Retailer report - Tortuga backpacks on: August 14, 2016, 10:43:13 PM
I love backpacks that can pack a lot and aren't bulky... I've been using a pretty regular 20$ Billabong for years and it has suited me quite well for general purpose. Well built, carries quite a bit of stuff (I can take clothes for a weekend out, maybe a bit more and my techy stuff - laptop, chargers, camera). Previously I had a 30$ one from Puma, but it was more bulky and eventually "disintegrated" itself...

Although these look great, I don't think spending 54$ on a backpack is worth it, much less 250$... But I might be completely wrong, so I'm awaiting on your review Smiley

Where is that rex hacker guy now?
If some one can track him down from his alternative accounts then they would be a rich man from Bitfinex.
Looks like they got alot of funds fast to put together such an amount in the prize bounty.  Undecided

If you're referring to rekcahxfb, he most likely wasn't the hacker... Cheesy

If you sent to the right address (which seems to be 1nTFLtFSdx7osRrPtVyrbrrL99LkBTmgz), then the problem is in the service you've sent the Bitcoins to... Doesn't seem like an Electrum issue.

Thank you for your reply.

lotmixing.org says i need to save the address that i send the btc from for my btc to be reflected in lotmixing.org

Question: Is the address I sent my BTC, the one stated in Blockchain? I tried to save that address but the website prompts:-

"Entered Address already exists, please try a different address"

Yes I understand it could not be an Electrum issue, but I was hoping that anyone with expertise on this can assist.

Yes, I guess that would be the address you sent your BTC from, which seems to be 15vYLohAz6o951fcj7Kzt9TtCk9M6pWLpu. If this results in an error, you should probably contact the website's support.
854  Bitcoin / Bitcoin Discussion / Re: Bitfinex Offers $3.5 Million Bounty for Stolen Bitcoin on: August 14, 2016, 09:55:19 PM
so did they lose this coin through a simple address collision or what?

The coins were hacked... a collision is practically impossible.

857  Bitcoin / Bitcoin Discussion / Re: Brain wallet password based on fingerprint? on: August 14, 2016, 09:40:15 PM
If bitcoin will use fingerprints password they need to have a very very good system for this type of password. Millions of prople are using bitcoin , so there will be millions of fingerprints, there will be lot of errors in log in. Maybe you want to login trough fingerprints but your phone is a bad model and it's scress doesnt reconize you fingerprints.

There is no "log in" in Bitcoin. You use your client as usual and you recover your keys via fingerprint/retina scan.

AFAIK only Samsung used a fingerprint scanner on screen and they've already ditched that... But yeah, I kind of get your point Cheesy

But yes, I agree 100% on retina scanning, as I've also suggested in my post. That would be the future. I'm curious as to what kind of randomness can we "extract" from an iris, as stated in my first post.
I'm pretty sure that people around here don't know that there's a difference between retina and iris scans. Retina scanning should provide better security but it does come with higher equipment costs.

That would have to be weighed in regarding data randomness obtained in both methods and if the security given by one method tops over the cost saving the other method offers.

But building further on the fingerprint idea: you can further enhance the security of something protected by fingerprinting using one's lips. So 10 fingerprints + lips print would be way much more harder to obtain and it wouldn't make the process of recovering a wallet a bigger burden.
Lip print? That would be very impractical if you ask me, but an interesting suggestion nonetheless.

Since it would only be to recover a passphrase, I'm not sure if it would be all that impractical (you would only use it once in a while). We would probably have to build hardware for that tho...

Lips are very distinct, and they're also used for investigation in forensics, hence my idea Smiley

Not a good idea.... We had a biometric scanner system linked to our payroll system... you clock in and out with a finger print scanner.. but some of the guys { those who did handyman jobs and work

with their hands a lot } had problems with the system not recognizing their fingerprints.

Yes, this is a valid issue to which I have no suggestions Sad

The other problem --> People will know that your finger print is the way to access your money and they would

simply force you, with violence to give up your money.. A password memorized and written down as a backup in a safe place, will never be trumped by Biometrics.  Wink

People could also force you to reveal your backup location...

It could be used as a salt behind your private key though.

Great idea too Smiley

And believe me, we don't want to go into Bio metric way of identity confirmation, soon we could be tagged exactly in a way cattle is.

Software attempting to communicate with a server somewhere, storing our biometric data would probably be detected by someone auditing the code.

First of all the idea is good but there are some other better biometric security way like Iris scanner that recently is introduced on the Samsung Note 7. I don't know if you know but the fingerprint can easily be hacked by some kids toys that use in kindergarten for more check this video how can an iPhone touchID can be hacked/tricked: http://www.dailymail.co.uk/sciencetech/article-3471718/Can-iPhone-s-fingerprint-sensor-hacked-using-PLAY-DOH-Researchers-claim-toy-bypass-Apple-s-security.html#v-5041464962111065112

This was what I was referring to back in the 1st page... To be able to replicate a fingerprint this way, you have to have it very beautifully "printed" on a surface, and that doesn't happen frequently in real life Smiley

Golly, you people are so much more security savvy than I am. I'd be dead impressed with myself if I was using fingerprints for stuff. I suppose fingers can be cut off and retinas gouged out. I'll be waiting for a scanner that reads my eternal soul. Until then passwords do the job.

Cheesy


To further enhance the fingerprint idea, one could create its passphrase using a specific sequence of fingers...

I'd still love to see this happen, fingerprint or retina scan or both.
858  Economy / Services / Re: [BIT-X.com] Earn Bitcoins by Posting | Signature Campaign on: August 14, 2016, 02:43:54 PM
Announcement

After nearly 2 years, over 330 thread pages, and more than 300 BTC paid out, the CoinsBank signature campaign will be closing down as of September 1.

I'd like thank every member who has participated, especially to those who have stuck through the issues until now (and until the very end hopefully).

A final payout and announcement will be made on September 1 for all members wearing the signature (normal rules applied).

Once again, thank you to those who made the CoinsBank signature campaign incredible! Smiley

Best regards,
Marco

I guess this was to be expected. Way too many issues with the campaign lately and Bit-x/CoinsBank already has a name big enough not to be bothered with these things. Sad for us that they don't need our advertising anymore, but good for them, it means they've fulfilled their objectives and have grown their own space on the market.

marcotheminer, thank you very much for running this campaign. Despite the issues, you've managed to pay every time and ran this campaign exceptionally well for a long period of time. It's probably difficult to run a campaign like this, so thanks for the effort.

It could also be that they are hoping that the hacker will return the coins in return for the 5%.

The hackers "loses" a lot in a deal like that, but it makes moving the coins a lot easier for him. Also, it basically removes a huge mark from his back.

We don't know what the reasons behind the hack are (most likely money), but if it is ideological, the coins might reach home with an offer like this.

Exactly... Couldn't have said it better. I think this is the main reason for a bounty.

Good fingerprint replicas aren't easy to make. They take time and that's probably not feasible in most attack vectors.
Adequate replicas are easy to make. You should do a bit research regarding the sensors used by smartphones these days. Generally, I think a iris scanner would be a better option.

History tells us that systems like Touch ID aren't easy to deceive with fake fingerprints, although it's obviously not impossible to do so. I'm not familiar with systems by other brands, but I assume the same applies. But yes, I agree 100% on retina scanning, as I've also suggested in my post. That would be the future. I'm curious as to what kind of randomness can we "extract" from an iris, as stated in my first post.

But building further on the fingerprint idea: you can further enhance the security of something protected by fingerprinting using one's lips. So 10 fingerprints + lips print would be way much more harder to obtain and it wouldn't make the process of recovering a wallet a bigger burden.

Jut my take on this topic... I think we can explore this much further, whether through the fingerprint topic or through the retina scan topic Smiley
