Hello All,

I have been trading bitcoins for a year now and although i always thought Bitstamp is reliable i am having doubts since what happened a week ago.

I am going to tell you a small story that explains what happened and i would like people to comment and check their views in what they think happened and also if someone has any ideas on how to tackle this it will be more than welcomed.
I will give a bounty of 3 BTC if anyones help proves to be important to solve this case....

So here is my story...


Last Friday I had around 6.000 $ in cash into my Bitstamp account after several bitcoin buy/sell and deposits of cash from my Bank etc. and so I decided to withdraw this amount. I did the process normally. This goes through an email verification sent to my email and I click on a link giving them the verification needed.

After several hours (after midnight of Friday 1st November, Saturday early morning the 2nd November) I changed my mind regarding the withdrawal of the funds and decided to cancel this and play a bit more with buying and selling bitcoins. Just before I go to sleep at around 2.00am I decided to sell all my bitcoins eventually and ask for a withdrawal of funds (again around 5.800 $).

So I did the same process again and pressed the withdrawal button. Then the funds disappeared from my account (as they should) and I felt that all is ok.

Next morning I remembered that I never received the normal email confirmation and so I never reconfirmed this withdrawal. Then I started emailing the support ofBitstamp.net and trying to see if it did go through. The support said that no 2ndwithdrawal was ever requested (the first withdrawal was the one I cancelled initially) and so the problems started.



After checking thoroughly the logs and history of my transactions what it shows is that I have withdrawn all bitcoins and have send them to another bitcoin address. . WHICH I NEVER DID.
 In fact it shows that I have withdrawn in 5 separate bitcoin withdrwal requests. The weirdest thing is that the way the logs show that I have withdrawn the bitcoins is the exact way I sold the bitcoins to bitstamp order book. But instead of showing sell in the log it shows withdrawal.

Of course I did not withdraw any bitcoins anywhere and that's why i am here now...

 

Recap

·         I make 1st withdraw of cash 5.960 $ the morning of Friday the 1st November. I receive the email confirmation and I reconfirm

·         I cancel the withdrawal and decide to play a bit more by buying and selling bitcoins

·         I decide to cash out everything by selling my 29.25 bitcoins. This happens in selling intervals of 10 btc, 8 btc, 5 btc, 5 btc and last 1,25 btc for a total of 29,25 bitcoins

·         I take all the cash and ask for a withdrawal in my bank account but never get that confirmation email I always get.

·         Funds do not appear anymore in my account and I decide to start speaking with the support. I get late answers from them and nothing specific. The only thing they say is the obvious (whatever is in the log) but not true of course.


Possible things that happened (my opinion)

 1. Someone managed to hack my email account plus my Bitstamp account and enter while i was already inside. Managed to take the bitcoins in the same sequence that i sold them?? and withdrew in his bitcoin address. At the same time i continued to show that i DID SELL the bitcoins and used the amount to make a Fund Withdraw. Highly unlikely
2. Bitstamp has taken these bitcoins from me
3. There is a SERIOUS security problem with Bitstamp that they know it but try to through some smoke...

Fact remains that i AM MISSING either 29,25 BITCOINS OR 5.800 $ (This was with 200 $ per bitcoin pricing- I know now its much more)

The serious security problem is very well known about.
They use cloudflare, which pretty much equates to a permanent MITM attack.

I have been dealing with bitstamp since mid 2012 and did 100's of quick sales and buys and some large one's and I was always happy with the service provided. The only time I had a problem was when once I withdrew 1900GBP and I only received 1720GBP and bitstamp fee was 10GBP so 210GBP went missing and neither bitstamp nor my bank had any idea where it is or how and why it happened.
If you are 100% sure you never sent any bitcoins, your account got taken over by someone else it looks to me.

Isn't there any way that these transactions (Bitcoin withdrawals to multiple addresses) can be rolled back?

Yes, if you can persuade 100% of all Bitcoin users to use an modified client that has rolledback your transaction.

Good luck with that.
