Most of the transactions coming to that address have 5 or more senders.  I don't think this is an individual, but a service/exchange that's holding onto a lot of people's coins.  Hope they have their security down Roll Eyes

Well they are using 3 Factor Multi-Sig at present
So whatever service it is has at least some rudiments of security down pat
Whether that means three distinct operators or one person controlling all three keys is another story XD

I might be a bit off given that Bitcoin values are fluctuating but total recieved is just a tad under 1 Billion still a damn impressive sum of money to move back and forth
91,559,816.63

With a total balance sitting
2,354,836.13 at time of observation.

Or Roughly 892 million moved over six months (148.67 Million a month) Equivalent to sell pressure of $495,500 a day if it was pure conversions to fiat (30 Days)

Not bad at all considering its first transaction was on
 2014-09-18 15:00:14
According to the first recieved txt on the address
https://blockchain.info/address/39ngTt6DWQRUbzjmx6ucxz7pPvQcm52CL3?offset=1050&filter=0

(If a billion was sold into the market that answers your question of how they swiftly sell, they are one of the main sources of volume that helps drive the price by taking all the demand and pushing it down converting to fiat.)

Not sex per se, but I do recall Mircea had a bounty for exposed tits that was paid in Bitcoin
That bounty was pretty generous when he offered it on a porn/stripper site and they didn't understand what MP was selling haha.
As for full on Sex not yet, but who knows it may be around.

Wagecan definite scam?


Xapo is ridiculous, anyone willing to use it?

Hell no

Indeed looking at that table its not worth it
Assuming the others don't run away with the assets at a later date of course, although the table did need an update as the Xapo affiliate mentioned
This seems like a good thread to keep track of since debit cards are becoming more common in Bitcoin now, still fairly limited in terms of selection but it is progress.

Xapo debit card:
Maximum card balance: There is no maximum. You can spend directly anything you have in your main wallet.
ATM withdrawals: $400 if you dont provide any ID or proof of address. Goes up to $2000/day as soon as you provide this info
POS purchases: Up to $2500 without ID/address. Goes up to unlimited when you provide this info
Monthly fee: Was removed in September last year. We pay this for our users

Note that we are not a preloaded card. Meaning you dont need to spend btc and load fiat onto the card. We withdraw bitcoins and load those funds in fiat onto the card immediately when the card is swiped.

The rest is correct. Let me know if I can clarify anything else  Smiley

It's so exciting reading reports of places like Africa and India becoming more knowledgeable and interested in learning about bitcoin. These are two major areas that could benefit the most from expanding this market.

I hope to see these conferences turn into development in the future
The applications of mobile banking and cheap efficient transfer could do wonders for their economy
Just the benefits alone from not needing to waste time walking to a bank to get cash if they live far out of town that can then be placed into working productively is worth the test.

But you know that isn't going to work very well here, so congrats to the officers they now have a brand new asset that no one will be bold enough to claim a piece of Smiley
586  Bitcoin / Bitcoin Discussion / Threshold Signatures and Multi Signature Development Discussion on: March 28, 2015, 09:18:01 AM
Princeton/Stanford/York whitepaper on Threshold Signatures
http://www.cs.princeton.edu/~stevenag/threshold_sigs.pdf

Download Link:
Here is the link to the paper (via google scholars)

Seeing as this topic seems/is too recent to catch much attention and people are more familiar with multi-sig transactions but not with thresholds at this time, I am raising the question and discussion, should future Bitcoin development focus more on Threshold signatures “stealth multi-signatures.” or on the development of Multi-Sig transactions.

As it is Bitcoin wallets often are attacked by increasingly sophisticated cyber thieves. Coupled with the irreversibility of bitcoin transactions, that poses important security problems that decrease user confidence in Bitcoin and as a result the Bitcoin ecosystem needs a breakthrough in security.

Bitcoin should be moving towards stronger integration in multi-signatures and development to inter-linkages among different devices, the question is how do we get there and what steps should Bitcoin moves toward in the future and what seems to be the most efficient/user friendly option.

Feel free to discuss it here.

Additonal info:
https://bitcoinmagazine.com/19528/threshold-signatures-new-standard-wallet-security/
https://bitcoinmagazine.com/11848/multisig-explained/

What a Threshold Signature is

The ability to construct a signature is distributed among different devices (for example a computer and a smartphone), and each device receives a share of the private signing key. For individuals, threshold signatures allow for two-factor security, or splitting the ability to sign between two devices so that a single compromised device won’t put the money at risk. For businesses, threshold signatures allow for the realization of access control policies that prevent both insiders and outsiders from stealing corporate fund.

Plain English:
* Key Difference (A private key can be split and does not need to be generated/reconstructed even after repeated signing)

What a Multi-Sig is

A multi-signature feature requires the signature of more than one private key to be spent. Multi-signature can, for example, allow an organization to give access to its treasury to its members while only allowing a withdrawal if 3 of 5 members sign the transaction. It can also allow future online wallets to share a multi-signature address with their users, so that a thief would need to compromise both your computer and the online wallet servers in order to steal your funds.”

Plain English:
* Requires multiple private keys versus a threshold Signature which can split one private key among different devices.
587  Other / Beginners & Help / Re: Multi-signature: what it is and a list of services on: March 28, 2015, 08:36:45 AM
Work in progress (quite obviously)

Feel free to comment with educational material I could use in the OP as well as services using multi-sig.
Well a little background information on what it does might be nice
Simply put its where it takes more than one signature to confirm a transaction this can be 2/3 with each party buyer seller and provider having one and transactions only succeeding when a user has 2/3 of them. 3/3 where they need all of them or any mix that requires more than one signature for a transaction to be processed.

As a note bit-x also uses multisig you can tell because all ID's start with a 3 instead of the traditional 1
Since you missed that one, unless your threshold requirements are a bit more restricted than sites that use multisig in any form or function.

Article:
https://bitcoinmagazine.com/19528/threshold-signatures-new-standard-wallet-security/

As for that discussion it is a step forward at least not the true solution though as the article points out

Multi-signature (multisig) wallets offer a solution. A multisig transaction, for example a 2-of-3 transaction, requires the agreement of the required number of authorized signatories, in this case two out of three. However, the paper shows that multisig transactions present significant usability problems, and serious anonymity and confidentiality drawbacks.

“Bitcoin currently lacks support for the sophisticated internal control systems deployed by modern businesses to deter fraud,” say the authors of the paper. “To address this problem, we present the first threshold signature scheme compatible with Bitcoin’s ECDSA signatures and show how distributed Bitcoin wallets can be built using this primitive.”

In a threshold signature scheme, the ability to construct a signature is distributed among different devices (for example a computer and a smartphone), and each device receives a share of the private signing key. For individuals, threshold signatures allow for two-factor security, or splitting the ability to sign between two devices so that a single compromised device won’t put the money at risk. For businesses, threshold signatures allow for the realization of access control policies that prevent both insiders and outsiders from stealing corporate funds.

The researchers built a prototype implementation of a two-factor secure wallet, a desktop client and an Android app, and released open source code on Github. A video shows how the system works: a user initiates a transaction on the computer, and the computer then begins the threshold signing protocol with the phone. The phone will show the user the transaction details and will proceed with the transaction only with the user’s explicit approval. The computer and phone use QR codes to initially pair, and for all subsequent sessions they communicate over the local Wifi network.

If threshold signature schemes become common, private bitcoin wallets will support the same multi-factor authentication offered by major wallet providers, while continuing to offer a high degree of anonymity.
588  Economy / Securities / Re: [HAVELOCK] Mintspare (MS) Bitcoin Electronic Trade-in Service - Official Thread on: March 28, 2015, 08:26:30 AM
MS is still operating. They have lowered their expenses. As long as they are providing a service to their customers we don't see any reason why the MS fund should be closed.

Any proof they're still operating?

You're an incredibly shady exchange. No vetting of new IPOs, no recourse for fraud (NEOBEE), and no de-listing of failing businesses (MS).

MS is in constant contact with us by phone the same way you can contact us by phone. We answer all phone calls and concerns. Judge us as an exchange not for companies that are start-ups and have a very high rate of failure in the real world and in the Bitcoin world.  Havelock is a crowd funding platform denominated in Bitcoins. We do our best to protect both the companies which list with us and the users of our platform.  If you feel that we can do better please feel free to contact us and provide us with your input.



So out of curiousity, how long should shareholders in a company go without any contact from Mintspare regarding its asset or news at all in terms of its progress, even a confirmation from havleock that the secruity is active before we can call it dead.

Seeing as its been around 1 year since any meaningful communication has occured, I can't say this asset has been providing any service to its customers or its shareholders.  
589  Economy / Economics / Re: destroying bitcoins on: March 28, 2015, 08:19:14 AM
In fact most of the coins in cold wallets are almost like destroyed, they are not in circulation for a long time

The key is to remove bitcoins from exchanges, when coins on exchanges are getting less and less every day,  the value will increase for sure, and an easy way is to purchase from exchanges and spend them

Was skimming through the thread to see if someone made that note or not
In essence that is the correct approach to take removing coins from circulation is the same as decreasing the monetary supply
Scarce coins means increased value, so while coin destruction does work the best way to do it is cold storage with coins going offline for long periods of time, although when they wake up Coin age will move like one heck of a crazy stat.

The strangest thing happened.  As soon as a stopped investing in bitcoin securities...

I had more bitcoins.

Ain't that the truth, well Bitcoin securities have had a very high tendency to suck
With very few exceptions all of them can be considered failures
In the end you really do have more Bitcoins avoiding them like the plague Wink
591  Economy / Economics / Re: 3-5% daily decline trend is back on: March 28, 2015, 08:13:19 AM
The price has only been down for a day. I'd wait a few more days (like 30) until I'd call it a trend. You can always consider it a buying opportunity, too, if it goes down to $250 or lower.

http://www.coindesk.com/price/

I don't know if this is seen as a trend by most of you, but Bitcoin has been on the steady decline for the past few months after it peaked.  Am I the only one who looks at Bitcoin like a stock? Because it is seeming like a shitty stock.  I think when it hits a ceilling for how low it will go, it won't really change too much. 

It is a means of exchange but if we were looking at it like a stock it's good on the fundamentals but in terms of performance price wise its sucking pretty hard, in other words the market isn't reacting to the news.
If we treat it like a currency it's dropping relative to all currencies lol.

Why didn't you create this thread when we were going up ?

Because when it goes up it's just a dead cat... I've shown this time and time again.

Well it seems like your winning this round
It's been a consistent trend for a while now new lows might be breached again sigh
Then retracing to a new lower high

uh? what satoshi minigame? what's Eulora?  Huh

The Ministry of Games (S.MG) is a public company which develops games. The first game by the company, which they are in the process of producing, is Eulora, MMORPG type game with a real bitcoin economy. You can see the wiki for the game at http://www.eulorum.org/Eulora or read more on trilema in the SMG category (paywall).

Well most people do not always check trilema but it's usually not behind a paywall if your an infrequent visitor
Thanks for posting a wiki link sort of forgot that existed after all this time

Current prices look ugly but graphs are currently indicating a floor.., what do you think?

Possibly, it might try to retest 300 again pretty soon
It couldn't last time maybe it will this time around.

seems like the floor was firmly set at 200, im not sure we wont go back there soon.  Below that, I doubt it, but 200 seems easily reachable in the right circumstances

Looking at it now I think your right we might be retracing downward to the 200 range than reaching upward to the 300 range


Good old chartbuddy

Now? There's been nothing left for over a year. Just smoke and mirrors.


Still a million dollar marketcap somehow.  I guess based on the chance that FC emerges?  Or that no one can get their shares from FC to sell them Smiley

What a mess.  I hope he has a change of heart and decides to come back and figure out a way to continue the company or dissolve it.  Running and hiding is childish, if that was his plan.

I'm a bit suprised there was still a working URL keeping track of the market capital
It's still quite the farcry from the days it was a 100 million dollar company but I guess the mighty have kept falling and getting weaker over time.

Blocking a selected few bitcoin address and will be difficult. It will be easier to can hire hackers to hack their accounts at the exchanges and steal all their coins.

Well I guess they can try Ip tracing
But that requires the help of Washington to trace the servers back and then geolocate the terminals
Not to find Bitcoin wallets per se but to target separtist PC's lol...
