Anyone whom had done business with Bitstamp would probably gotten an email indicating problem with Bitstamp. The key information is, if anyone deposit Bitcoin on or after January 5th 2015 will not be honored, meaning your Bitcoin is gone where it’s 0.0001 BTC or 100BTC all gone. However if it’s a large amount, you can probably check with Bitstamp suppose to get it back if possible.
It is official that Bitstamp hot wallet got hacked. Bitstamp had suspended its service on January 5th, 2015 and at this time it’s still down, no ETA. Let just hope Bitstamp hot wallet don’t have a whole lot of Bitcoin in there. Both Coinbase and Bitstamp, and probably many others stored their Bitcoin in a cold wallet, hot wallet would only hold small amount for constant transactions. Meaning your Bitcoin is safe if you deposited a couple days ago, it is in the cold wallet and also guaranteed insured by Bitstamp and Coinbase.
There’s a conspiracy theory going around right now. People are saying that Bitstamp did this on purpose due to the fall of Bitcoin price. Bitstamp might not be making much money on transactions, on top of that Bitcoin value plunged, so with no revenue, no profit, Bitstamp decided to make stories saying they have technical problem, all sounds so familiar like MtGOX? as they will take advantage of this and stole all the bitcoins moved it somewhere else and sell it later. The same conspiracy theory with MtGOX, in which the Police are investigation its staff possible stealing the Bitcoins instead.
BITSTAMP SERVICE TEMPORARILY SUSPENDED
We have reason to believe that one of Bitstamp’s operational wallets was compromised on January 4th, 2015.
As a security precaution against compromises Bitstamp only maintains a small fraction of customer bitcoins in online systems. Bitstamp maintains more than enough offline reserves to cover the compromised bitcoins.
IN THE MEANTIME, PLEASE DO NOT MAKE DEPOSITS TO PREVIOUSLY ISSUED BITCOIN DEPOSIT ADDRESSES. THEY CANNOT BE HONORED!
Customer deposits made prior to January 5th, 2015 9:00 UTC are fully covered by Bitstamp’s reserves. Deposits made to newly issued addresses provided after January 5th, 2015 9:00 UTC can be honored.
Bitstamp takes our security and soundness very seriously. In an excess of caution, we are suspending service as we continue to investigate. We will return to service and amend our security measures as appropriate.
