So as bitstamp has been hacked, I wonder if blockchain.info is safe enough?

Thanks Grin

Should be safe for sure. But its always recommended to just store small amounts there and create a cold storage for any larger amounts.

Keep in BTC only what you want to "play"(speculate) and nothing more. Do not keep large amounts in Bitcoin at all. The money must stay with "you"(house, bank) but not in BTC

It is not a wise idea to hold large amounts of value on any site (wallet).

Simply..
If you think Blockchain.info not save anymore, just get out from BC, and find another Walllet what you think safe.

its been de-listed from the main bitcoin .org site as one of wallets to be used, so im guessing its not safe anymore.

not customer's lack of secure behavior.

The other problem is there is no proper definition of what is the "customer's lack of secure behavior".

BC might also return funds if the amount is small, what if they get hacked to the tune that Bitstamp got hacked... or even worse Gox?

(And yes, I do use them myself... Grin

but not for 100% of my coins)

be sure they won't pay any BTC back. they will close the business like the wallet Inputs.io, hacked

So, the online wallets are hacked often. blockchain.info = online wallet = very possible to be hacked AGAIN as IT WAS in the past.

I think blockchain.info wallet is safe. People lost bitcoin on blockchain.info because they using unsafe methods to access their wallet. I still have my wallet there.

blockchain.info was hacked.

who said that is it safe? it is not safe.

hacker : ""Every bitcoin transaction is signed by two values – 'R' and 'S' – which prove that the sender knows the private key. If the same R value is used twice, the private key can be easily computed from the signatures alone.""

and then read this :

"Even if the manufacturer claims that it runs open-source code, how do you tell whether it is actually running what you compiled?" Verbücheln said.

But as far I know, Blockchain.info never failed to return coins when the loss was due to their own fault, not customer's lack of secure behavior.

we do not debate whether Blockchain.info is or not fair. we debate whether the Bitcoin wallets are safe and THEY ARE NOT.

Well Basically Online wallets are less safer then Offline wallets .
so I personally don't recommend you to use Blockchain.info or Coinbase or anything simillar to that , just use Offline wallet like Multibit , Bitcoin Core or Electrum ... or if you wanna be sure about your protection and you have huge amounts then just buy Hardware wallet

Blockchain maybe safe at some extent, but I would like to share what I experienced during the past days:

A few of my transactions have been marked as Double-Spend, even though I didn't do it... It was a bug, but it took nearly a whole day in order to show the actual available funds in my wallet... So, you should better go for Bitcoin-Qt Desktop Wallet if you are to do some huge amount transactions...

Everybody has to make his own conclusion.

This is the best practice for me:

online wallet like blockchain.info: storing bitcoins worth up to 10% of the monthly salary. If it's unavoidable (exchange), storing more than 10% for a short time period is ok.
local hot wallet like Multibit, Core: 10-100% salary.
offline storage: bitcoins worth >100% montly salary.

Think of it this way, it's easier for a hacker to hack into an on-line wallet but it's not as much easier to hack an off-line wallet which never sees the light of the internet.

I wonder what the relevance is in discussing Bitstamp when asking about the safety of a wallet service. The two are completely different.

But no matter.

Blockchain.info has a few security considerations to take into account. Malware on your computer can steal your coins by monitoring you entering your passphrase. Furthermore you need to ensure that you have a backup of your private key stored somewhere safe (offline) in case Blockchain.info decides to just go offline one day. Finally, recently there have been issues with Blockchain.info using a weak random number generator, which allowed attackers to decypher some private keys and steal coins. Fortunately, most of this was done by someone with good intentions, so the coins could be returned, but still.

All together, I would only use Blockchain.info (or any other online wallet) for day-to-day spending money, not to store larger amounts that aren't being used.
