My whole transaction history has disappeared, i cannot access my coins

[jackg]

Sorry it took me a while to reply. I have a flu now on top of the distress (though the news about the apparent 1.6 btc is perhaps better than any other medicine....of course 10000 btc would be a better medicine but anyway). Im just feeling sleepy and confused.

Now i started looking into other possible bitcoin addresses that i have, and i just noticed something and this clears things up a bit:

15FyEELVAzyKiWNQA888SDPDyZdB1Czrqj is the address to my ledger nano (havent really been using it, had certain issues with that too [yes, i dont know why but i always get some crazy issues with technical devices, but there is enough of a headache already so lets leave ledger out of this]) and i do remember sending a small amount to it, so i can confirm to that transaction. Apparently i just imported the casascius private keys to the electrum () since it shows transactions going from the casc public address and i made that transaction using electrum.

As for the 0.6 btc, well that should logically be the time i sold the 0.6 so yeah

As for the 5.0 bitcoins, now that is my WTF moment. I dont remember doing that. But if i still have 1.6, its weird if a hacker left that, and since the two other transactions are most obviously mine, i guess i must be behind this one too. I just cant imagine how i would transfer 5 goddamn coins and not remember it  My own memory is starting to scare me now. Now i imagine i would have transferred that to a btc wallet of my own and somehow forgotten about that, but it shows a lot of transactions happening after that so it cant be cold storage??? I dont think i have a bitstamp account and if i do, im pretty sure ive made that later.

Did i just iuwbgiubgiebwiugbw 5 coins ?

Wow what the fuck is going on.

----------

Well.....how would you guess suggest i get that 1.6 btc out safely? Import the private keys again, then move them wherever? Im asking cause to me it seems at this point its smarter if i dont do damn thing before someone else verifies im not doing something dangerous. I seem to have a skill at fucking things up which is a skill i dont yet know how to use in the most productive manner.

-----------

Thanks for all the support ive been receiving, i really appreciate it. I can already feel my mental health repairing itself a little bit, maybe i dont have to go live in a crazy people home after all (and i wouldnt wanna spend the rest of my money on the treatment).

What ive learned:

-Keep everything in order and pay attention to security
-Backups, so i dont have to come back online and whine about whats going on
-Unfortunately cannot trust electrum anymore, the transaction history is still lost
-Im not made to deal with crisis situations or with losses, i better avoid these scenarios like the plague they are
-I cant trust myself, i thought i could, but 5 btc and the blockchain disagree and i cannot argue with that. I have to deem myself untrustworthy which kinda sucks cause i have to rely on myself anyway.
-The community in bitcoin still works, so you guys are alright 

Make a seed in a newer version of electrum and go to sweep the coins into there. You can write down your seed beforehand then and write down the private key also (optionally encrypted).

As near as I can figure, you sent 5 BTC directly to a deposit address at an exchange (possibly Bitstamp)... It didn't go anywhere near your Electrum wallet. I suspect you may have "swept" the funds directly to the exchange.

For the record, that was the same day (15th August 2015) that the Bitcoin XT fork happened and the Bitcoin price was "only" ~USD$260... (10 days later it was $214, according to this: https://99bitcoins.com/price-chart-history/ )

Does any of this trigger any memory? Perhaps you were cashing out before the fork?

Back then, your 5 coins were maybe $1250-1300... about 1/5th of what the 1.6BTC is worth now!

Anyway, what you do with the 1.6BTC you have left is up to you... Do you want to cash it out or keep it? If you want to cash out then just sweep the funds into a new wallet of your choice.

If you want to keep it, maybe you should consider moving to a new wallet as well, given the lack of faith in the current private key... If you didn't send the 5BTC then it may have been compromised.

Damn. I used coinbase at that point so couldnt cash out anything from the fork .

Anyway, OP if you have a main email your using, search that for sires like bitstamp and coinbase and other exchanges at the time and see if there's anything you can get in regards to where your coins are.

I used sweep to put the 1.6 into a new electrum wallet

https://blockchain.info/tx/1799965988b878401c49810b70e08da23e91fc65af3537bb6d4e56b5c6a5c76d

There has been a block after that, but it says unconfirmed and the electrum wallet also has 0 confirmations. And it looks like it indeed went out of the casc bar....

Are they gonna be stuck??? I could not customize the fee which is 0.19325 mbtc

Oh my fuck did i fuck up the coins i have left???

[Numerous64]

OH two confirmations. Ive never seen the word *confirmation* with it looking so beautiful. Damn. I deserve a beer you guys

I did not even know of the fork. This seems unlikely to me, but my skepticism is on steroids now cause i cant remember doing that transaction either. Maybe i just have some serious memory loss now. Ive deleted emails from that time, for sure. I guess i need to start by looking at all the papers i have and see if any in them give me a clue of what has happened.

Maybe contact bitstamp to see if there is an account relating to my email.

Well im glad i got my 1.6 back, at least all this was not for nothing. I think 1.6 is worth the stress after all. You guys have a time machine so i can go back and a. save my coins b. slap myself in the face???

Your 1.6 btc are still safe.
And, if you wait to  remember where the 5 btc were then your future self will be even happier (even if it's still without a time machine to remember how exactly the 5 btc ended up where they did (wherever they are).

I used sweep to put the 1.6 into a new electrum wallet
https://blockchain.info/tx/1799965988b878401c49810b70e08da23e91fc65af3537bb6d4e56b5c6a5c76d

I don't want to be an alarmist, but did you move your 1.6 BTC after you sent it to Electrum?? Because those coins have been moved... At least twice since the transaction you say you did to sweep them...

https://blockchain.info/tx/41d857b8605e86581f6a406083733cc95653cff5ea8ef80fc5ce18c9849dd74c

They appear to have been consolidated along with a number of other UTXOs into a 359+BTC UTXO... Again, possibly an exchange or other web service consolidating deposits into a warm wallet (given the destination address has had 25,000+ transactions and over 3.25 MILLION BTC deposited!!?! )

Your 1.6 btc are still safe.

You sure about that?

Also, @jackg, can you please stop quoting entire posts and then just adding 1 or 2 sentences... It's really annoying and makes it difficult to follow the thread with massive walls of quoted text everywhere... Thanks in advance.

[Abdussamad]

so he has malware on his system and he just fed it more coins. sad. should have diagnosed the earlier problem first before sweeping his casc private key. sorry for your loss op.

[HCP]

Hmmmm seems that the address it ended up in: 12cgpFdJViXbwHbhrA3TuW1EGnL25Zqc3P belongs to Poloniex... so someone has sent those coins to the deposit address: 1Dfat2qDcdAh9Tjgux59U7jHzKwHt8LHbW at Polo, and Polo have then consolidated it all...

I'm really hoping it was the OP moving his coins... they sat around for nearly an hour or so before being sent to Polo, so it doesn't seem like an automated bot...

OP, did you create a brand new Electrum wallet? If so, and you didn't send the coins to that 1Dfat2 address, then as Abdussamad has suggested, it is highly likely your machine is totally compromised

He probably moved them into an exchange for some reason, considering we got the updates when he was worried about the coins being sent to the other address and having them pending for a while (he probably mved them for something such as 2FA or to try to margin trade them for a profit or even invest them in an altcoin).
@OP, even though an exchange offers IP security and 2FA it's still not a great option as a place to store funds.

Your 1.6 btc are still safe.

You sure about that?

Nothing is ever 100% safe. Once something touches the internet it enters a critical state and has potential to be hacked.

I'll try doing that on my PC. If I'm on my phone, I have only 512mb so loading chrome tends to crash it a few times. But i'll not that.

[Numerous64]

Omg

Sorry i was afk for a while, getting the situation out of my head.

Yeah i moved them to my polo account temporarily, no need to be worried about that.  I just forgot to mention that. Yeah im not gonna leave them there for a long time.

Whoa well. What a situation.

Glad to hear your coins are 'safe' then.
You can store a small amount on poloniex, I just wouldn't recommend storing 100% of what you had (unless you split it between exchanges but even then that's risky).

It might be of use for you to look into hardware wallets like trezor or ledger, or for you to attempt to start using a paper wallet (preferably encrypted) to store the coins as storing them on an online computer may not be your safest bet.

[Numerous64]

Yeah thats my plan. I have a trezor wallet but i havent initialized it yet (i recall i had some sort of an issue with it... ,,,yeah ). Plan on doing that tomorrow and then moving my coins to it.

[HCP]

Good to know your 1.6BTC is "safe"... Now if you could solve the mystery of the 5 BTC...

but yeah, leaving sizeable balances on exchanges is not recommended. I would definitely get your Trezor up and running as soon as you can if I were you!

So i put bitcoins to my electrum wallet on a usb 2,5 years ago. I made an another topic on the matter earlier on

https://bitcointalk.org/index.php?topic=2130374.0

But i recovered my wallet file and the seed is not wrong, and i have the password right. The transaction history is simply not showing, and it tells me i have 0mbtc which is not true.

Can you tell me what exactly do i need to do? Yes, the green mark is connected, ive let it sit there for an hour and i still get no transactions. Do i need to connect to a different server or recover my private keys from the wallet file or something else? What do i do to access my coins now?

I got the same situation with my wallet. I save a true seed from Electrum, but it not synchronize history.
Are you restore your bitcoins? I can help you in this.
