The thread they post the private keys to has now been moved: https://bitcointalk.org/index.php?topic=1175321.0

Has anyobdy here successfully transfered coins to a personal address? I assume it is not unlikely that they spend transactions right before revealing the private keys to possibly reduce liability or to increase their troll level.
How big of an effect do attempted double spends in this number have on the network? Do higher fee double spends clear lower fee transactions of the same outputs out of the mempool?

No, as I understood, ordinary people don't have a chance to claim these free coins. You have to know very well what you are doing and chances to claim the coins have only specialized bots, that can be built by the people that know what they are doing. Us regular people, that will try to claim them will just play into Coinwallet wishes and clog up the network.

These actions will have the same impact as a regular stress test, just that it will be done by the greedy users, not by a single entity like Coinwallet. It will raise the fees and give us numerous unconfirmed transactions.

For the rest of your questions, I will let more experienced users respond.

It would be interesting if one could see how many bitcoin users imported those private keys into their wallet in an attempt to sweep some of those keys.

Also, how can one be certain that they are actually giving away these bitcoins. Could they not perhaps have set themselves up before hand to sweep the majority of the funds right back to themselves? It would mean that they get a big PR exercise going at little or no cost. Personally I think that this PR exercise, if one could call it that, has backfired in a big way for them.

Well you can observe some double spend attempts in the block explorer of your choice.


I don't think any standard wallet implementation will cope with these outputs. It's probably best to create raw tx and broadcast those with appropriately high fees. I would be interested if anybody succeeded in manually snatching a couple of coins before the bots could.

they can do what they want but:

dont use this service, it is a scam!

I tried last night although i don't have very good knowledge but most of the keys have 0.0004BTC available and hundreds of transactions.It is very very hard to succeed to transfer even 0.0001BTC from these keys.All this is waste of time on name of giveaway.

i try this giveaway...
but i think like everyone else, it is just a big waste of time!

Eh, another foolery/trick of those malicious guys to use the people in creating a stress-test themselves. Do you think people would just let those 0.5 btc laying in there when they can get it themselves? I don't think so. Many will be tempted to claim that and send that to their own address, thus creating a transaction. You might know the next part, given that coinwallet.eu will be revealing more and more private keys in the following weeks.

If our greed consumes us, we, the people of this community, will be creating the transaction backlog in the network for coinwallet.eu.

if it looks like a scam, feels like a scam and smells like a scam - there's a high chance of it being a scam. don't use anything related to them.

It was too good to be true.Yes,you are right no one gives free money and why they to not take out by themselves instead of letting others to take their money.People already begin to claim to transfer some bitcoin successfully and one of them is newbie.This is a network of scammers to scam the greedy people.

Tried on Mycelium and it went into sync mode for wayyy too long, and not sure if it ever would.  So for anyone that did this, disable all network connections and delete that account.  It is not worth the small amount, but this is worth watching and a very nicely done experiment by Coinwallet.eu.  I'm not even mad.

yeah by the time you sync that crap, you will discover that everything was sent to another address already, i'm not going to bother anymore

but someone was successful in evading some coins

it is not a giveaway people. wake up!

they are obviously asking for your help to attack bitcoin, and anybody who is greedy enough to try and use any of those private keys are directly contributing to "spam attack"

Nodes seem to be crashing, so much for nothing happens if we hit the limit. Admit it 1mbiters, the crash landing scenario is real...

 Thay are doing the same on Reddit

https://www.reddit.com/r/Bitcoin/comments/3k8odg/coinwalleteu_stress_test_cancelled_bitcoin/ (https://www.reddit.com/r/Bitcoin/comments/3k8odg/coinwalleteu_stress_test_cancelled_bitcoin/)

Any official news that stess test has ben cancelled

I think the motivations of coinwallet are not promoting the blocksize limit. As apparently they even don't exist as a service, thus they are using that excuse to simply attack the Bitcoin

In only 24 hours after the start of the "giveaway", the unconfirmed transactions pool is saturated, every block is ~1Mb, and soon nodes and online wallets will face problems. The giveaway will be performed only today, but as people will keep trying to claim those coins, the problem will last several days, even weeks. The bitcoin network is under attack, and as a community we should react and minimize its effects. This spam attack is based and works thanks to the greed of users, so unfortunately we can't cut the origin of the problem...

But there are for sure some things we can do and I am thinking about something very simple: I suggest the mods to ban the coinwallet.eu user, to close their giveaway topic and prevent any future attempt to publish those private keys. I know that technically they are not doing anything illegal. Technically. But every minute those keys are available, more and more users will attempt to claim them the next days. So I think we should prevent more inexperienced people to put those keys in their wallets, making the problem keep growing

Actually a very effective attack.

They've turned every greedy user into a bot for their attack.

Agree with the previous poster that you might just do more harm to your own wallet than anything else. The chances of anybody getting anything worthwhile from those keys are next to zero.

Why do people keep saying attack? If bitcoin is attacked by doing what it is meant to do - - - transact - - - then it obviously is not doing it's job very well.

Coinwallet are demonstrating and by real world evidence proving wrong all the 1mbiters who said that we can just hit the limit and all would be dandy. It wouldn't. You'd be waiting in line, pay exorbitant fees, and all of it for the privilege of allowing some retard on dial up to run a node. Super smart.

That is a very good argument. As people is contributing to the attack due to their greed, we should use this as the primary argument: Is for the sake of their own wallets

i think there are a lot of things to do to secure your bitcoins...
first of all i think to don't keep you bitcoin in exchange wallet!
