2  Economy / Service Discussion / Bitstamp warning DO NOT DEPOSIT - they delay crediting funds on purpose on: April 10, 2014, 11:33:55 PM
I deposited a big amount of money on Bitstamp on April 1st.  When they received it they also came with these stupid 6 KYC questions and it always took them 2 days to respond when something was missing or unclear. Now they wrote me 2 days ago that i have passed the KYC program. I wrote them several messages - without response since then. I still do not have the money in my account.

A company that acts that way is highly suspicious. This delay really cost me a lot (not only fiat inflation) as i really need the funds and they act like they don't give a shit.

DO NOT DEPOSIT. USE KRAKEN instead!!

4  Bitcoin / Development & Technical Discussion / Easy solution to prevent 51% attacks from doing any harm? on: January 21, 2014, 03:44:29 AM
Hi folks,   I often read that many people are afraid of so called 51% attacks. I really don't  understand the big deal about it.  

********1st problem: Double Spend Attack*********

Here my solution: Can't we agree that our full Bitcoin Nodes never automatically overwrite these parts of the Blockchain that are older than let's say 1 hour  (or 6 confirmations).  Normally orphaned blockchains never contain more than one additional block, so there should not occur any problems.  

In the rare occasion that there is a longer fork and you have the shorter blockchain the program should ask for manual selection of the blockchain that should be used.  
For unlikely cases like

* http://bitcoin.org/en/alert/2013-03-11-chain-fork
* an real 51% attack
* Australia gets disconnected from the rest of the world  and you live in Australia  or whatever :-)

I think it would be safer if users can manually handle these events.  

*******2nd problem: Mining Empty blocks ********
Gavin also found a good solution (changing the protocol to reject longer chains in some cases): https://bitcointalk.org/index.php?topic=78403.msg874553#msg874553


******3rd problem: Prevent all other miners from mining any valid blocks  ********
If the attacker doesn't do double spend attacks and includes all transaction but just ignores all blocks from other miners it could be a problem. Other miners would soon go bankrupt and the attacker would gain even more % of the network....

I would suggest the same solution like with problem 1.  Any Miner or any Full Node shall not overwrite a Block that is older than 5min in the case that such an attack is ongoing.

******
  So overall I suggest to include a manually adjustable parameter, that allows every user to set the timespan in which overwriting existing blocks remains possible.  
In case of emergency it could be set to 5min
Full Nodes could set it to 60min  and  
simple Nodes  or Nodes with bad connectivity could set it to infinity....

Hi, a couple of people have not been paid for over 2,3 or 4 days.    Just thought it is about time to make a new thread!

Edit: wtf FloatesMcgoates?   Who are you and can you please stop posting if you have nothing to say.  Bitconsports.eu  is scamming several customers (all with rather big amounts)  

http://www.bitcoinsports.eu/inv/6bc71   10BTC

http://www.bitcoinsports.eu/inv/aa8e3    7BTC

http://www.bitcoinsports.eu/bet/f6799   1.5 BTC

http://www.bitcoinsports.eu/bet/0b590?destination=bet-slip 10BTC

http://www.bitcoinsports.eu/bet/72f9a?destination=bet-slip  5 BTC

... and counting....

8  Bitcoin / Bitcoin Technical Support / Very dubious Transaction, still pending despite fee after >10hours - Resolved! on: November 07, 2013, 01:40:53 PM
Hey,

I made a transaction  of 5.384  BTC  with 0.0001 fee included  more than 4 hrs ago.  

from 1QDRDaVZ2oXfXXWbkf98ebcfT9y2x8LZHN

to  

Status: 0/unbestätigt, über 8 Knoten übertragen
Datum: 07.11.2013 10:10
An: 1E67jR6bvbkcHEMhmDPqJcEaiTsscGtX7b
Belastung: -5.384 BTC
Transaktionsgebühr: -0.0001 BTC
Nettobetrag: -5.3841 BTC
Transaktions-ID: a9cbbaa4341f0eae9d2c6d86b6d60032c81e93dcb262aec14ad5232715cc0f16


The Receiver already confirmed the transaction.  

Just out of curiosity:  Why is that taking so long? Normally it only takes seconds even for non-fee transactions without confirmation to appear on Blockchain.info

9  Bitcoin / Bitcoin Technical Support / Bitcoins sent back to sender address and are now gone? on: October 22, 2013, 08:28:56 PM
Hi,

damn. I think i just lost 4 BTC.   I thought i own this address

***

Yesterday I sent 10BTC  from this address to **.

Today i just cashed out 3.935 BTC to this address  but it doesn't appear in my wallet!  

Wallet is synchronized but the balance is still unchanged.

Is there any way to retrieve the 3.935 BTCs?   Dont really get what I did wrong? Thx for help.


I use the normal BTC QT client 0.85

I have 4 receiving address listed under Tab Receive

***

There are many services that return funds only to the sender's address.


All resolved.... Now it's in my wallet!  Strange. Normally it takes only seconds....
10  Local / Trading und Spekulation / Bitcoin.de Support hält sich nicht an Gesetze und gibt Bitcoins nicht heraus. on: August 19, 2013, 04:21:16 PM
Hallo,

muss hier mal ausdrücklich vor Bitcoin.de warnen!  Bin dort schon seit langem Goldmember und habe >80 Transaktionen durchgeführt und  bei diesen zum Glück nie Probleme gehabt und somit auch nichts mit dem Support zu tun gehabt.

Nun habe ich vor einem Monat dort 10BC's von einem Bronze Mitglied gekauft (etwas unter Wert). Dieses Mitglied handelt unter falschem Namen und mit einem anonymen polnischen Kreditkartenkonto.  Dieses Konto hat ein Transaktionslimit von 2500€, dass der Verkäufer fast ausgeschöpft hatte. Meine Überweisung kam also  nach einigen Tagen als Überweisung zurück. 

Einen Nachweis meiner Zahlung habe ich an Bitcoin.de geschickt. Bitcoin.de ist außerdem bekannt, dass der Verkäufer verdächtig ist (falscher Name + falsches Konto).  Trotzdem hat der Support die Transaktion abgebrochen, den Verkäufer nicht verifiziert und mich negativ bewertet. 

Kaufvertrag ist Kaufvertrag. Wenn der Verkäufer kein korrektes Bankkonto benennen kann, ist das sein Problem.  Eine Klärung mit der Verkäufer hat sich als aussichtlos herausgestellt - dieser gibt weder korrekte Personalien noch ein korrektes Bankkonto preis. Die Bitcoins hat der Verkäufer wahrscheinlich rechtzeitig wieder ausgecasht. 

Der Support versucht, die Sache unter den Tisch fallen zu lassen. 

Mir ist auf jeden Fall ein recht hoher Schaden entstanden, wenn man vergleicht, was die Bitcoins jetzt wert sind...

Ich werde wahrscheinlich gegen Bitcoin Klage einreichen und dort nicht mehr handeln...
