CAUTION: blockchain.info wallet don't let me login to my wallet

[el kaka22]

Here is my story:

I've signed up a blockchain.info wallet months ago and I've been using it for no problem. At one point I've added my email to improve my security, however since that point I need to confirm my email before EVERY login. Yesterday I'm still doing this with no issues. However, when I tried to login to my blockchain wallet today, I don't receive the confirmation email even for submitting the login form few times. However without its email, I can't login to the wallet and hence I've lost control of 2 empty addresses which I haven't backuped.

Fortunately I've got a backup of non-empty addresses from them a week ago. Then I could still have control of my addresses, and having no loss in bitcoin. I don't recommend everyone using blockchain.info wallet.

Also a noob question here: I have private keys (in both compressed and uncompressed formats) and wanted to import them to another wallet which allows me to sign message. Can anyone give me a suggestion on this?

I had the same issue with you, didn't receive Authorization email but this is not the first time.Let's wait till tomorrow. I think you should post this in service discussion instead of scam accusations.

I never import private key to another wallet before, can't answer this.

Blockchain.info bugs are know things. Btw, you should move this to Service Discussion.

Both allows you to sign message. Check the format of your address because you won't get same public key or same address with those two private keys.

P.S. FYI: There is no thing as compressed and uncompressed private keys. You can't compress a private key.

I don't recommend everyone using blockchain.info wallet.

After I read this I got very scared and now I move my coins from there
Just jocking, good that you don't lose any coin
A got the same problem but in some hours I got my confirmation
Don't worry be happy.

You can contact support and they will likely remove the restrictions on being able to login.

My experience with bc.i wallets is that you will only need to confirm via email anytime that you try to login from a browser that you have not previously logged in from. If you are being sent an email every instance of you trying to login then you are probably clearing your cookies.

I am not sure however why you are accessing wallets so often that don't have any funds associated with them nor am I sure why you would not immediately backup your wallet as soon as it is created. The former is just wasting time and the later is a horrible security practice and will most likely cause you to lose access to significant amounts of money.

A much better way to store your private keys is with a deterministic wallet. All that you will need to save is your seed, regardless of how many addresses are in your wallet and your chances of loosing your money is overall lower. You can also use this kind of wallet in similar ways that the bc.i wallet is used as you can easily access your wallet from multiple secure computers by recovering your wallet from the seed.

as long as I use blockchain, there has never been a problem. Although many say there is a problem with blockchain, but I've yet to find it.
but I use it only for small amount.

This is the better way
I never kip more than 0.5 on my blockchain because the rest is offline
API is broken for a long time.

I personally stoped to using bc.i, I have bad experience with their wallet , I lost my coins there, although I set up the 2FA and strong password but my wallet still can be hacked and stolen my coins, I don't think if my PC is infect to virus or ect because I've scanned my PC

Just made a successful login there. Locking this thread, until I can't login there again.
P.S. I only have less then 0.1 BTC at blockchain.info, so it is safe for now.

[el kaka22]

Today when I login to my blockchain.info, they don't let me send my 0.115 BTC away from the wallet (because the tx is unconfirmed). I've got my private key there. Where can I broadcast a tx by private key besides blockchain.info!

From your full node! If you don't have a full node then PM me the signed transaction and I will broadcast it for you!

(if you are making money from a signature campaign -as you are- then you should invest the small amount of money necessary to run a full node; you will support the network and will be giving back to the community, and will help make your existing bitcoin worth even more!)

How to run a full node? My computer don't have enough space (see https://bitcointalk.org/index.php?topic=1093151.msg11663705#msg11663705: I've mentioned about my small computer storage). Also I've tried brainwallet.org, but they only recognized the 7.7M satoshi output (but not my 3.8M satoshi change).

You will want to rent/lease a VPS, I use RamNode and it costs about $14 per month, and they accept Bitcoin. You will want to get a VPS that has at least 2 GB of RAM and you will want to use Ubuntu 10.04 as your operating system. Once you get your VPS, you can follow instructions on Bitcoin.org on setting it up. I got a few error messages when trying to set it up, however it was nothing that a simple google search couldn't help me fix.

Once you get your node setup, you can use the sendrawtransaction command to push your transaction to the network and doing so will ensure it will stay propagated even if you include a small fee (it may still not get confirmed though). This won't solve your problem of building the transaction, you can do it manually (although this is risky as it is easy to make mistakes), there is brainwallet although this is not perfect, and there are a few other options as well. You could add your private key to your node's wallet.dat file to have bitcoind create the transaction for you although storing your private keys on a VPS can be risky because it is possible for others who share your physical server to "listen" to what is in your RAM (your private key would need to be stored in RAM unencrypted when bitcoind signs the transaction).

Do they accept bitcoin? I don't have a PayPal account yet. Also as what you said, storing a private key on a 3rd-party server is dangerous, as the bitcoins would be stolen. Also, I don't have the raw transaction, because I don't know where to sign it and how to sign it. Could anyone give me suggestions?

Yes they accept Bitcoin, IIRC via bitpay.

To build the transaction, I would use electrum; you can create a new wallet that is restored and enter the private keys that you need spent. In most cases, electrum should be able to push your transaction to the network, although I prefer to use my node because it will be rebroadcast every 30 minutes if it has not gotten confirmed yet which increases the chances of it getting confirmed.

The risks of storing your private keys on a VPS are very different then allowing btc-e (for example) to store your Bitcoin for you. If you have your funds held on an exchange then you need to trust the exchange to honor your withdrawal request and you need to trust them enough to keep your funds safe (eg not get hacked). Storing your keys on your VPS is similar to storing them on an online computer. Although a VPS will generally be connected to the Internet 24/7 verses your computer being connected to the Internet only when you are using it so someone could try to hack your VPS while you are sleeping/away and you wouldn't be around to notice. Another difference is that your hosting provider will have physical access to your server and could potentially look at what is stored on your VPS, although this would be illegal in the U.S. (And most of the world) without a warrant so the risk of this is probably pretty low. The major risk of a VPS is that you are sharing a physical machine with others and the people who are on that physical machine could potentially easedrop on what is in your RAM.

I experienced such yesterday also, when I log into my account my balance was displayed but when I clicked on send fund button I did not see any coin in the account, I got scared and do all I could nothing came up until when I log out and log in again.

[el kaka22]

I just confirmed my problem: that is my output doesn't got a confirmation because of the stress spam, and so that they don't let me spend or sign that as input. Locking this thread again.
