PayPal os only safe when you are dealing with payments from and to recognized institutions or traders. Buying or selling bitcoin via PayPal is very risky. I am a victim after losing $500 and my account PayPal account frozen.

Bitcoin is virtual goods, so you cannot buy it with paypal. I heard it somebody said that in the forum.

There is a trusted user named BayAreaCoins in the currency exchange section. I bought paypal money from him some times and i consider it relatively safe. One shouldn't buy from an untrusted user though. As long as no dispute comes up inside of paypal then it would not be a problem that a digital good was traded.

Not to sure about this website, I've purchased a item from a users amazon list. Inserted the tracking number a day later.  The package is marked as delivered on USPS's website but I never got the bitcoin.

Contact the admins, you need to do this not seldom to clear things. Might be the buyer only forgot to release the coins or other reasons.

I believe administrators can release the coins to you too.

still broken in chrome. looks exactly the same

Do you have the latest version of Chrome? If so, do you happen to have ad blocker enabled? Maybe this would make the page appear distorted. I had once a similar problem with another site and I was able to fix it by disabling ad blocker. Hope this helps.  Smiley

P.S. It is looking fine for me, on my latest Chrome browser.

Clearing browser cache might be a chance too. These cache things in content management systems can be a real pain. And way too often one forgets about one or another cache that can be the source of the problems. Roll Eyes
1425  Economy / Scam Accusations / Re: Master-P's scammed funds summary. Post your case here if you were scammed. on: February 03, 2016, 11:23:07 PM
It's likely that it will be hard to get this amount with signature campaigns.

And for master-P's victims it would be interesting to merge forces with the other scammed members. Informing them about the connection and the more are involved the lower will be the costs.
I personally think the best bet would be attempt to make contact with his other victims from past scams, collect more solid evidence that all these thefts were in fact done by a single person and then contact law enforcement. The more money that was stolen, the more attention that law enforcement will generally give to a criminal, especially if there are multiple victims.

The ~$10k that master-P stole would probably be sufficient to get the attention of Law Enforcement, however his various stories (even with all their holes) might be enough to give reasonable doubt, and might be enough to get his victims to not pursue him. I somewhat get the feeling that he "read" his victims and repaid those who he thinks were most likely to pursue him, and stiffed those who he thought would not.

I fully agree with you. And the law enforcement should have not much trouble finding him. He did not run or anything like that... There are other scammer who are, unfortunately, harder to find.

Though when i say that... still nobody visited the address. And it might mean that there is nothing to find. There are enough ways to scam this.

Everyday we read about new scams.
Scammers growing like mushrooms after rain..
How to trade safe, to whom to believe?
And people makes mistakes with such stupidity..

I can only tell you that using an escrow is momentarely the best way to prevent being scammed. Very often scammer vanish silently already when you tell them you contact the escrow. Some play it smart and back out after the escrow had work with the contract. Most probably to find a valid sounding excuse. Still a prevented scam, though often enough people don't tip when a scam was prevented with escrow. Even though he had work and saved the user coins.

I know there was a well known escrow scamming lately but that is pretty seldom. An escrow is increasing safet ALOT.

If someone has a deal you can ask me, see my user profile to find my servicethread.
1427  Economy / Trading Discussion / Re: How I was scammed ...... on: February 03, 2016, 11:12:43 PM
Not sure why everybody is saying it must be a "malware".Most easiest scammed he pulled off.Teamviewer gives control of your computer to him.He would have simply opened your wallet and sent the bitcoins to his address.Its as only screen sharing as you thought it is,he basically controls your computer from his chair.

EDIT : About typing the wallet address ,he would simply copy pasted it from his browser if it was on bitcointalk or pastebin I suppose.

But wouldn't this first need that the user enables the option that the other partner can interact on his pc? I think the default setting is that the partner only can see and there is a warning before you give him the right to move the mouse on your pc and such things.

So what happened here? Were the rights given?

How can raising the second number increase security?
Quote from: SebastianJu
The key will create a bitcoin address the site owner controls. So no error but manual change in code for purpose of scamming would be possible.
I think you misunderstood: not 'raises security', we understand 2-of-N's vulnerabilities and are limiting N to 4. We believe 2-of-4 provides added securites while limiting the risk involved. With 2-of-4, by your example, if someone dies then the coins wouldn't die, or if the site effs-off then there will still be 3 legit parties. If we only offered 2-of-3, people could reuse their keys, generating reused multisig addresses (as you know, three keys will always create the same multisig address). The fourth key is the random server private key.

I didn't know 2 of 3 would create always the same multisig address, though when i think about it it makes sense. I somehow awaited a random factor like with mnemonic phrases for wallets. Though makes sense.

But what i meant with lowering security is that the lower the first number and the higher the last number the higher the chance of a possible scam happening.

For example 2 of 4... it only needs a corrupt escrow who comes out as a trader and trades. Then one person has the power to release the coins. 3 of four would be more safe then since it will be harder and harder to impersonate more parties.

By the way, when will the server give his key? The one controlling the server might be one of the involved parties too.

And the higher the last number the higher the chance that 2 are the same person again.

Quote from: SebastianJu
Merchants might already have established enough trust to not having to care about escrow anymore. But if they do then an automated system looks faster.
There are faster and more user friendly systems available, however keysCrow was built to give our users the control over their transactions they deserve. Not automatically doing things for users gives them piece of mind of knowing exactly where their Bitcoin is going. What if the site begins to create faulty rawtransactions or changing destination addresses? This prevents that scenario.

Yeah, for some shops a buyer really would prefer protection. Though i think that the merchant needs to offer it first. I mean the merchant would agree that he only gets his payment after the buyer receives the goods. That surely is not for every merchant.
1429  Bitcoin / Development & Technical Discussion / Re: Why soft fork is a very bad idea and should be avoided at all costs on: February 03, 2016, 10:41:33 PM
Thank you for the explainations. I'm not so much into the details of the tech so i appreciate to learn how it works.

So when the witness is segregated into a parallel block then the amount of data to be transferred and to stored would not be less than if you would put the same amount of data into a normal traditional block? I thought this was one of the main reasons that were brought up against raising the blocksize limit. And the segwit nodes would have to verify the transactions, which then would mean the CPU would still have to work on, let's say, 2MB worth of transactions.

So the internet use, harddisc space and CPU-Usage would not be lower for the same amount of transactions than with traditional blocks?

sturle, you say that it is very unlikely for an old node to create an invalid block. Though segwit surely won't start with the majority of miners. So when segwit hashpower is at 10% of the net then no segwit blocks will be created, segwit blocks start at 95% of hashpower only. So 5% of the blocks would have potentially a chance of being invalid blocks because the old nodes can't see that some addresses already have their bitcoins taken away and they might try to spend them again. Though it doesn't sound like a big problem since when segwit reached that threshold then it is sure that it won't lose that power anymore. It would be safe to switch.

But it is not sure that segwit will reach that, right? Though it would be the same like with the old nodes. It would be safe to assume that segwit wins and that this transaction will never get invalidated.

So it is sure that segwit blocks only start to be created once segwit nodes hashpower reach 95%? I have read it differently, like it would be done from the start to enforce the adoption. So implemented in a different way than previous soft forks. So it is definitely the case that the old threshold is used?

To be honest... at the moment i don't even see anymore why segwit is an advantage when the arguments against 2mb blocks, internet, cpu and harddiscspace usage, are not changed. So it is only easier to raise?

I guess i misinterpreted since that sounds strange.

1431  Bitcoin / Bitcoin Discussion / Re: The real disastor that could happen (forking Bitcoin)... on: February 02, 2016, 09:29:17 AM
You are right, they will chose one chain. But that doesn't say that they can check incoming deposits against the deposit on the other chain. When they received the bitcoins not only on their chosen chain but on the fork too then they can accept that deposit because it is riskless.

Why should they not monitor the other chain and instead close down completely? That makes no sense businesswise.

You are talking nonsense (again) - if you accept coins that end up being on a failed fork then you cannot spend them. Got it?

So if I am exchange A and I accept coins on Fork A and am giving someone fiat for those coins then I've already spent the fiat and end up becoming a bag-holder of a useless alt.

Now tell me why any business is going to take on such a risk?


You write as if this exchange wouldn't own the same address on the other chain then too. But they would ideally. Well, probably depends on the way their wallet creates addresses. Core might be not good if i remember correctly.

But let's assume they own the same deposit address on both chains. Then it would not matter if they receive the coins on both chains and the chain they used on their exchange suddenly dies. They still would have the coins on the other chain. Nothing would be lost.

I hope you got now what i meant. Smiley
1432  Bitcoin / Bitcoin Discussion / Re: The real disastor that could happen (forking Bitcoin)... on: February 02, 2016, 09:25:37 AM
..Because a blocksize increase means faster and more frequent transactions and faster confirmations.

Actually you only misunderstood him. He meant that a transaction will receive confirmations faster, blocks won't be found faster then. But a transaction will most probably be implemented in the next block. So his sentence is fine.

Doesn't this apply to SegWit as well?

Yes i think so. Though Lauda wrote like the author of that sentence was so stupid to think that the confirmation time (the 10 minutes) will be lower. At least i interpreted it so since the sentence otherwise would be fine.
1433  Bitcoin / Bitcoin Discussion / Re: The real disastor that could happen (forking Bitcoin)... on: February 02, 2016, 09:23:59 AM
I don't see why it is fine for you to run a softfork that activates after 75% of the hashpower is using it or a hard fork that goes life after similar thresholds. Double standards? It would still show that the majority supports something.

All soft forks so far have only been enforced after a 95% threshold (and this will apply with SegWit as well).

The only people trying to push for a 75% hard-fork are Bitcoin Classic, Bitcoin Unlimited and Bitcoin XT (the latter being now defunct).


Yeah, though the chances are not fair if you think about it. 75% is the majority of hashpower for sure. That's the first point. Then they can do it.

The otherside will make segwit come with higher threshold and lightning network without decision finding.

The problem is that the core developers block the raising of the blocklimit and they can enforce it. So in fact they force all the rest of the community to follow the way they want it to be. I think they can not complain about classic doing a similar thing. Classic at least would know the majority behind themself at that point. Coredevs don't really care about such decision.

In order to allow a decision there is no other way than to present an alternative. So at the end coredevs complain about the possibility to vote. They decided for themselves and for all to not raise the blocksizelimit. Everyone had to follow. Force. Now a way to find the opinion of the community was found and they complain about that happening since they already did their decision for us all.

No, i think the worse enforcer are the core devs. Deciding for everyone without giving a choice and when someone creates a choice then he wants to break everything in their eyes.

Bitcoin is not a democracy (have you not even read Satoshi's paper?).

Satoshi said 1 vote per CPU (not 1 vote per person) so surely you can understand that one person can have more than one CPU?


Yes, in this sense it is not a democracy... maybe a technocrazy... cpu's are voting... Cheesy So at the end the wealthy has more power. Was inevitable. But still it is some kind of decision finding. And the strongest wins because he can.
1435  Bitcoin / Development & Technical Discussion / Re: Why soft fork is a very bad idea and should be avoided at all costs on: February 02, 2016, 09:13:01 AM
So what i ask myself, when the old nodes only see empty blocks, aren't the transactions needed to calculate if the block hash is correct? If the transactions are not seeable then how can the hash be calculated as valid? As far as i remember, changing the transactions of a block will give you another seed part that is used as base to find the block hash.
In old nodes' view, it is just an empty block with a coinbase transaction, nothing special,  like those blocks generated by SPV mining. So the hash function will return OK signal.
Wrong.  All transactions are recorded in the block.  Only the signatures are moved.

Do you speak about the time that will be used by segwit to reach 95%?

You are right. If Segwit nodes only have 10% of hash power, then when they publish their block, the block will be accepted by core nodes, and core nodes see nothing in it. But in Segwit nodes' view, that block contains a transaction that spent Alice's coins. Core nodes does not see this transaction, thus they believe Alice's coins are still there, but in Segwit nodes' view, it is already spent

As a result, later when core nodes trying to spend those Alice's coins, that block will be accepted by Core nodes but not Segwit nodes, so a fork will happen. The fork happens because Segwit nodes does not have enough hash power to prevent core nodes to publish Alice's transaction. If Segwit nodes commands more than 60% of hash power, then core mining nodes will never be able to spend Alice's coins, because all their blocks are orphaned. And there will never be a fork
Wrong.  An old and a new node will have the coins at exactly the same places.  The UTXO set will be identitcal.

Then were comes the less datausage from? The signatures are not needed to verify the tx?

sebastian why not use NXT asset exchange? its fully decentralized and working for a long time now with a lot of volume. and its easy for your shareholders to use it

Actually we tried that first. But it is very complicated, has a learning curve. Then the problem was that the issuer would have to pay in nxt and solutions to pay in bitcoin did not match well.

Counterparty is very easy to handle so that i have high hopes that it will work fast there.
1437  Bitcoin / Bitcoin Discussion / Re: Blocks are full. on: February 02, 2016, 08:59:21 AM
I'm not aware of such errors. Can you give some examples?

One bug would have resulted in the block reward coming back (at 50 BTC per block) when it should have been zero (so the supply was not actually 21M).

He didn't even predict GPU mining (that seemed to take him completely by surprise and he basically asked people not to do it).

(and there are plenty of other things)


*lol* The GPU-Mining is actually pretty funny. I really did not anticipate such thing from him. Well he probably was surprised by the worth bitcoin reached and had not thought through the following effects.

The thing with the block reward sound like a software bug that might happen when coding. Well, it would have been enough time until that effect would have been triggered. Tongue
1438  Economy / Scam Accusations / Re: Master-P's scammed funds summary. Post your case here if you were scammed. on: February 02, 2016, 08:55:43 AM
Surprise surprise, who would have thought that it ends this way...
I have to say that I am surprised about the majority of the situation. I personally did not think that master-P was planning a long con exit scam. Ironically, it would not be all that difficult to make as much BTC as master-P ended up stealing by trading honestly if he were able to find a niche market of some sort -- he probably would need to commit some kind of initial investment, either monitory or time, though.

Quote
Regarding escrow.ms's offer. I wonder if it would help master-P alot too. Since when the victims get their coins back from escrow.ms then there might be no one anymore who wants to prosecute master-P. Why invest the time and money when you are even?
Probably not. The individual amounts that master-P stole were generally small and I would find it unlikely that many/any of his victims will invest significant time into seeing that he is prosecuted.

escrow.ms previously had master-P on his trust list and escrow.ms likely wants to compensate people for the illusion of trust that this gave master-P (even if escrow.ms had no reason to believe that master-P was a scammer). I don't think that escrow.ms will be able to make any significant dent in the amounts owed to victims. Several months ago, my signature earnings peaked at roughly 1 BTC per month, and that was with ~800 posts per month. It is my understanding that victims are owed somewhere round about 10-15BTC or so.

Quote
What i wonder too is, why is no victim of the other scams coming in here? Did they give up? At least i would have awaited that some of them show up, but it seems nothing happened.

Are they not aware of the connection?
master-P's other victims are likely not aware of the connection, and I would not be surprised if they have given up on trying to collection of the money stolen from them.

It's likely that it will be hard to get this amount with signature campaigns.

And for master-P's victims it would be interesting to merge forces with the other scammed members. Informing them about the connection and the more are involved the lower will be the costs.
1439  Bitcoin / Bitcoin Discussion / Re: The real disastor that could happen (forking Bitcoin)... on: February 02, 2016, 08:35:23 AM
Fake bitcoin classic nodes would not be able to raise the percent of support since they aren't actual miners. At the end the amount of hashrates are mattering.

Hashers can throw their power behind a classic miner then later withdraw their hashing power.

What would be the sense of doing so? You can't send a reasonable amount of hashingpower to fake nodes just to try raising the hashrate, you would need to put real power into it. And you would only do this when you are sure that the fork wins. You can't fake hashrate like you seem to suggest. At the end it comes to the blocks that are found. And when a classic node miner has XX TH and spreads this hashpower around 10 fake nodes then on that chain there still would only be XX TH from that miner.

I think you mix the kind of vote the XT fans tried with actual votes by hashpower. It's not the same and the number of nodes decides nothing.

And when a fork happens then when support for this new system raises a high value which means everyone will switch then since it is very unlikely that they will drop again then.

As I've stated I don't think we are just dealing with sensible people making sensible decisions.

If Bitcoin Classic were to stick to the way that soft forks have so been done (95% before activation of the new feature) then all of this controversy would go away.

If the vast majority of people do want 2MB blocks then I don't see that 95% should be a problem (and for the record I don't really care if the blocks are 1MB or 2MB).

It might be that the problem is that one can foresee that there will always be more then 5% miners that categorically would block such a change. Which would make it impossible. On the other hand 75% is a strong sign of the will of the community, well miners aren't actually the community but comes near to it. And it's better to let the majority decide instead staying undecided.

At the end it doesn't matter. Sigwit might get taken over by the net realitively without problems, ln doesn't need a fork but i doubt it will be used very much. And at one point in time it is inevitable anyway to raise the blocksize. It's grinding some time, that's all.
1440  Bitcoin / Bitcoin Discussion / Re: The real disastor that could happen (forking Bitcoin)... on: February 02, 2016, 08:26:22 AM
I think they need only to check if the coins reached on the deposit address on both chains. Then these coins are safe. It doesn't matter then which chain will win since they have the bitcoins on both chains.

Huh?

You are not making sense. An exchange is going to on one fork or the other (not both unless they want to be giving away fiat).

If your exchange decides on Fork A and then Fork B finally wins out then that exchange will go "belly up" (as all the coins it has had deposited would be unsalable).


You are right, they will chose one chain. But that doesn't say that they can check incoming deposits against the deposit on the other chain. When they received the bitcoins not only on their chosen chain but on the fork too then they can accept that deposit because it is riskless.

Why should they not monitor the other chain and instead close down completely? That makes no sense businesswise.
