PROBLEM SOLVED!!!

People in this forum are simply amazing. This thread was so informative, everybody so helpful and I have learnt a lot!

Here is the explanation to what happened:
The guy was not very good at English, so he was using Google Translate to read my comments and translate his own responses.
I did not realise this; If I had, I would have used very simple language, and read his comments more carefully, to figure out what he really meant.
He meant to ask me to confirm the BTC Address to send to, again, even though I already given it.
He had not in fact made the transaction but went to bed, awaiting a final confirmation from me, which he thought he had asked for. Combination of language problem and lack of question mark just made the comment turn out wrong for him.
It sounded as if he had sent the BTC and wanted confirmation that it had arrived.
Because of the time differences, I was asleep when he was asking about this,  and couldn't respond. We had already agreed he would send the BTC when the money arrived at his account. He just wanted to be 100% sure about the address.
Then he was asleep as I got confused by his comment.
Now he's up and trading and has sent me the BTC.
Just as I thought - the guy is very nice and completely trustworthy. My female intuition is not so good for love, but for business, it works!

I was particularly happy to be trading with somebody who's using BTC in a "live" situation in Venezuela. Apparently they use it there to buy everyday things + it's enough of a struggle for them, with American blockade, political turmoil, hyper inflation and whatever else is going on.  
I like this guy so much, I'll buy from him again.  His rate was very good too.  I'll just be aware that the World Remit is not always as fast as it ought to be.
 
BIG THANKS TO EVERYBODY WHO HELPED ME LEARN NEW THINGS TODAY!

The difference of the EUR figure mentioned is just because I sent the money in SEK (Swedish) not in EUR. When writing here, I wanted to mention the price in a currency that people are likely to be familiar with. SEK is not a big currency, so  I just did a very sketchy calculation in my head,to give a rough estimate. Then somebody specifically commented on the sum, so I decided to double check and it turns out I was off and the value in EUR was a little bit higher than I thought.  Exact price for anyone who is really interested, was "Buying 0.07592263 bitcoins for 6,885.00 SEK". This is approx. 611 EUR. Sorry about any confusion.

The payment method he asked for was World Remit, which was new to me. Register and then use your Visa/Mastercard to send money. The seller said the transaction with World Remit would be complete in 1 hour. However, as it turned out, it took close to 4 hours. His window for the transaction, was something like 1.5 hour. Additionally, it was late at night, I was not at my sharpest and aware I needed to go to bed. When the window was nearly up, I was warned by Local Bitcoin Exchange, made a stupid gut reaction, i.e. closing the trade even though the transfer was already made.

As for me handling this the wrong way: I knooooooow!!!  I started out by explaining that I realise that I did everything wrong and that this may be the price I have to pay for learning that lesson. I am angry with myself and feel very stupid.


Yes. I really thought I was dealing with a nice Christian guy who was trading BTC to make a living in Venezuela. I even chatted with him a bit while waiting for the transaction. I am normally very good at telling bad people from good, but of course, I am not God, so I don't know what's in people's heart!

Sometimes CIRCUMSTANCES makes an otherwise honest person behave dishonestly. Here, I had already transferred the money to him and cancelled the trade by mistake. Maybe, sitting there in Venezuela, with all the challenges the people there are facing,  it seemed to him like "money from the sky", simply too good to reject.  He could accept the money and not send any BTC, and probably get away with it. He might not even be sanctioned by Local Bitcoin Exchange. It's between him and his conscience.

I have now asked him to provide the Transaction ID, Re-send the BTC or refund my money
To be continued...

Thanks for checking! I recognise those figures you list, because I made two transfers earlier. The time also checks out.
I see the Address in the Addresses section of Electrum.

However, neither of these is the transaction I made with him.
Any transaction he made, would have been later in GMT - around Midnight or 01:00 GMT, by my reckoning.

Okay - that clarifies the situation.
The transaction he's talking about, was not made, and I can confront him about it.  
Odds that he made a mistake, seem pretty slim to me.
I doubt Local Bitcoin Exchange will help me, since the transaction was cancelled and outside their site - but it's worth a try.

I messed up and it seems he took advantage of it. The problem was, it was late at night and the World Remit transfer didn't take <1 hour as advertised, but something like 3.5 hour and this made me lose my calm and act stupidly. I guess 611 EUR goes a long way in Colombia/Venezuela... Maybe from his perspective, it's worth skimming a European who doesn't have her wits about her.
 

- Do you have multiple wallet on localbitcoins.com or blockchain.info?  Answer: No. Just one Local Bitcoing Exchange account - I'm not sure what it's address is. The missing payment was sent to an Electrum address.
- Is the wallet in question an old or new one? Answer: The Electrum wallet in question was set up in 2014 and has been only sporadically used. The Recieving address is constantly refreshed in Electrum though.

- Are you sure, you actually log-in to copy this address when you sent the wallet address to the buyer or you just copied already saved address from your computer?Answer:  Yes, I double checked. I could not have copied another address and I compared before I posted. (See screenshot).

- Finally, do you normally access your coin both on mobile & computer (notebook/desktop...)? Answer: Only on Desktop - I don't have a mobile Wallet.

Thank you for sharing your story, SoldiersWithLittleFaith!

Thanks everyone and sorry I disappeared for a while. I should be working really!

Here is the recipient address I gave the sender.
This was in the Recieve Tab of my Electrum yesterday night. He wrote that it's the address he sent to, including the address, for confirmation.

1JW9NJneiHVqpvDgcNah4FLXRF62Mw1Np5

Sum in Bitcoin: 0.07592263

I double-checked that it's what I sent to the seller in the chat on Local Bitcoin Exchange. It is also what he said that he sent the payment to, via chat on Local Bitcoin Exchange. This guy gives every sign of being honest and decent and a chatted a bit with him while waiting for the payment. I just don't get scammer vibes from him at all, even though I realise anyone could be tricked. His high score on Local Bitcoin Exchange also indicates he's honest.

It's in fact worth more than I thought in EUR, it's EUR 611. I paid him in another currency.

Now I will read all the responses since my last comment, very carefully to understand it, then follow up.

In the meantime, I would be super grateful for help by an experienced person, to check the blockchain.

I understand what you are saying about the Transaction ID and I will ask him for it, if needed. It's still really early for him, due to time zones and it would be good to know the verdict of Blockchain first!

This is the first time I've had problems with a transfer, so from that perspective it's suspicous.

Thank you! I checked Block Explorer but I'm not sure what I'm looking at. I can't immediately see the BTC being there.
Is it safe if I post the details here? If I mention the sum and the Receiving address, would somebody be able to help me check and interpret?

Thanks for an excellent explanation! Got it!

Thank you! So I understand the responses so far, to say that:
1. It doesn't matter whether Electrum was open or not - the payment should reach me when I open Electrum the next time.
2. The old address can still be used.

The only thing that remains then is (a) Check the Blockchain, which I asked for help with, if it is safe and (2) Ask him to verify that he sent the BTC by a screengrab of his Outgoing transaction.  

I am not very experienced and now, something has happened that I don't understand. I hope somebody can help me understand what happened:

Somebody was going to pay me, on an Receive address generated by Electrum. (This was a purchase Local Bitcoin Exchange, and the receipt of his payment was delayed at his end. I cancelled the trade, when I hadn't received the BTC during the allocated time on Local Bitcoin Exchange. This was a mistake by me, of course

The guy said he'd send me the BTC anyway, assuming the payment arrived.
So I pasted the Receiving address from Electrum in the chat, on Local Bitcoin Exchange.
I closed down the computer that Electrum is running on and went to bed.
This morning, the guy (who is in South America while I am in Europe), had pinged me.
He said he sent to outstanding BTC to the address I gave.
However, the money has not arrived.

I realise that he could be lying, but he is a top rated trader of high volumes on Local Bitcoin Exchange. Let's assume he was honest for the time being.

• When I open Electrum this morning, the Receiving address is something different than it was before! Why?  
• Is the Receiving address I gave him yesterday no longer valid now?  
• Electrum wasn't open when he presumably sent the payment. Is that a problem for receiving it?

What has happened here, from the BTC / Blockchain / Electrum perspective?  [/b]

(I realise this is my mistake for cancelling the trade, instead of Disputing - it was late and I was very tired, not thinking clearly and got stressed. I understand that the guy might have lied or otherwise tricked me, in using such a slow method of tranfer, so please advise me only on the Technical aspect of this - worst case: I paid EUR 550 to learn this lesson.)

No I think its mBTC. Confusing.
I only had 2 bitcoins at most.
So the balance in Electrum is in mBTC.
Which means I have nothing.....

I just logged on to Electrum. I thought I had sold my bitcoins...
However Electrum shows a balance of 0.92? See pic...
How do I know the balance shown is correct?
Electrum is connected.  

How has Wright been supporting himself? He owns 3 properties in various locations in Australia.
If he is Satoshi he has access to an unbelievable fortune!
He's got kids - are they in great school (who wouldn't spend money on their children's education, if they had it?)

If he really was Satoshi and didn't want it known - then he shouldn't have done that panel shown in the video. Or he should have had a cover story ready instead of dropping "I am Satoshi" hints left, right and centre.

Why did he go for a Japanese name? Does Wright happen to be a huge anime fan, and fluent in Japanese? Or maybe he has some other connection to Japan?   Check his Facebook.

Satoshi's writing has been with Commonwealth spelling, not US. That supports his being Australian. Of course, it could be "planted" but the comments in question were made long before anyone had any hunch Bitcoin would take off.

Seems he's close to the heart of Bitcoin either way.
Perhaps he was number 2 in a duo headed  by the guy who died.

If being Satoshi was a crime, could Wright be convicted?
I don't think so.

On the other hand, he may have been part of an original duo and he may have leaked the info on purpose because it suits his agenda at the moment. 

One thing I don't get is how a guy so talented with access to a bitcoin fortune lives so modestly.
Even if he doesn't care about money, he's got a wife and children.

Anybody with children who had access to a fortune, even if they don't want to spend it on themselves, would invest on the best possible education for their children.

What's the story with Wright's wife and kids?

Well I am the original poster here (lost access to the account).
I should have listened to you and used Electrum. But I got so angry and suspicious because the "official" client didn't work. Plus I had problems finding a way to buy bitcoins in the UK.

Can't believe I didn't buy any Bitcoins in December 2012 when I posted this....

Imagine if I had spent a few hundred pounds, as I wanted!

Instead, I bought them at ten times the price now, in January 2014.... In the meantime I heard Max Keiser talk of bitcoin on RT during the autumn. Lately taking some time off work, I listened to tons of podcasts and now I am up to speed.

I was sooo close in 2012! But I dropped out because QT was so useless and hung. Seriously, this client is a liability. I have a high spec PC but it just didn't work.

My impression at the time, was that it was "buggy". I wasted 2 weeks on and off trying to get the QT current operational... Then I got so annoyed that I just dropped out altogether

And now I am running Electrum, just as flatfly suggested! 

I think that QT has become a liability. The download page should actively discourage n00bs from using it, and point them towards a light client instead.

Are you saying that there is no point mining AT ALL unless I buy a dedicated mining rig?

I'm not in the market for that right now. Plus it seems to me, anyone doing that should live in a country with cheap energy to get really good value.
Or scavenge off electricity at work, or something like that.
Right?

I live in London, so I realise it's not profitable to mine - but I want to try it anyway...

My desktop machine happens to have two Nvidia cards. Model GT 430 , nothing special.

Can I mine anything at all with this machine, and in that case, what mining software do you recommend?

I tried GPUminer but I was only able to mine with one of the cards - don't know why.

I also tried Bitminter's client. It mined a bit faster than GPU miner, but the cards got a bit hot. Had to take out a PCI card that obstructed the airflow.

What is a "Cuda miner" and is this what I should go for, since it's dedicated to Nvidia? If so, which is the best and where do I get it?

I could really do with some advice! Hope somebody can point me in the right direction?
 

Doesn't seem like this thread is monitored regularly.

Perhaps better lock it if it serves no purpose to post here.

I spent a lot of time to try to find the details of my other account, could have been better spent just staying active and logged on for 4 hours.

Oh allright! I see.

I happen to have two graphics card in this machine, becuase I have two different monitors and I couldn't get the monitor setup I wanted with just one card --- it seemed at the time.

Ok so, mining really increases resources then... Well mining at work should be good then, but it could get awkward if they decide to run a network wide scan to see what software is running and/or submitting network traffic....


Desktop PC which happens to have two graphics cards (nvidia decent spec). What do you think?


I can't measure the energy consumption from the actual PC, can I?

I run my stationary PC 24/7 because I seed torrents....

Will it consume MORE energy because if I mine, than if it's just standing and seeding torrents?

Any idea what the difference might be?

I am pretty put off by Bitminter requesting Open ID to sign on.
It is provided by Google, Microsoft &  co.
These IDs set flash cookies, regular cookies etc on your machine, and then track where you go online "for marketing purposes". What NSA does with the info is anybody's guess.

I know this sounds paranoid, but it's a matter of principle.

Any comments on this?

Can anybody recommend an alternative mining pool for newbies?

Had an account here, Freja. Cannot access it - forgot pw and cannot get to email.
The forum was out of newbie restrictions (old style). Please can I be granted the same, or my old account pw reset?

I have an existing account here for which I don't seem to have the correct password and I cannot access that email account. Did not set a security question. Can anything be done?
User name for that account was Freja and the email freja at live.fr
Can anything be done?
