Also, as someone mentioned about importing private keys is not a good idea. I tried sending bitcoins from one account to another but the fee is an issue for me but for those who are OK with the fee, it's fine. If at any time a user forgets his/her password and he/she cannot access the wallet, that's when the private key is useful.

I believe it is more of safety than anything else. The previous wallet provider may have logged the private key and could compromise your wallet if they want to. Especially since wallets like blockchain.info allegedly stores encrypted private keys on their server. If the encryption is weak, then your wallet would be compromised.

The reason is blocktrail hasn't had such issues like blockchain and blockchain has been down for maintenance for about three-four times this year which causes a lot of transactions to get delayed. It again is your preference on what wallet to choose. However, blockchain and blocktrail aren't that different in terms of safety issues.

From what I have heard, I don't neccesary need to change to an other online wallet. I just need to backup my private key. Would it be ok if i store it on a usb?

As long as it doesn't get corrupted, you would be safe as long as you can remember your encryption password (when exporting encrypted) and make several backups. I would still strongly recommend to change your wallet, there is simply no point in going with them anymore.

I hear some people to reccommend others to stop using blockchain and use blocktrail. I also know that blockchain is down or attacked often. What should i do?

for me there is not problem using blockchain.info as my wallet because i have my private keys back up written in a paper and in my mobile so even BC was down i am still able to spend my coins

as for a blockexplorer, i still prefer using blockchain coz im familiar with it already but if there are some issues i temporarily switched to blocktrail. maybe you can try what im doing

I am also in similar situation as I haven't used other wallet except blockchain till now. I haven't lost any funds except some temporary unconfirmed transaction due to those attacks on blockchain. Will wait for some more weeks before I consider shifting my wallet and I suggest you the same.

Blocktrail is a good wallet too. But for your safety, do not store more than 0.1 btc if you don't own private keys.

Since blocktrail don't give you permission and no features to export private keys.

You still have choice to use multibit or electrum wallet.

Wow, so if they want they can steal everyone´s bitcoin who uses their wallet?

They could possibly do that. I believe they do not allow control over any of the keys used to sign the multisig address. The only thing they give is the seed which can be used to recover the wallet.

I do not consider any online wallet as secure if they:
1. Can potentially capture the private key or do not allow users to know their private key,
2. Are able to push updates without permission from the user.

Even though most online wallets create the wallet in the browser and do not send the unencrypted version to the server, they can potentially push an update such that the informations are captured. This is the main difference between desktop wallets. Desktop wallets require your permission to update.

That's not what i mean. The key for your safety is private key. If you don't own it you can't control your wallet.

It's like you store your btc in exchange. Which is you don't own your private keys. Only can send and receive bitcoin.

I remember sometime asking a similar question about importing private keys for other wallets. I got told that this is not a really good idea.. and that to move fund from wallet A to wallet B I should simply send myself the money (from A to B wallet), instead of importing and exporting private keys. If you can this practice should be avoided... just create a new wallet and send your funds there.

I believe that has to do with HD wallets. When people create a new HD wallet from seed, and then import private keys from other wallets, they forget that which addresses are not natively derived from seed. When they restore the whole wallet from seed later on, they loose the keys of those imported addresses, potentially loosing coins. By sending the whole balance to the new HD wallet (abandoning the old addresses), a restore from seed all always retrieve all your coins.

My suggested solution does not forfeit the use of old wallet and addresses, it provides a secondary access to your existing addresses.

Not a surprise considering many other web wallets do the same, people are using Coinbase even when they know that Coinbase can take all their coins at any time. If I had to choose for a online wallet I'd choose greenaddress, multi-sig address and many other security features, best web wallet I've seen. But still do not use any web wallet for amounts over 0.1, use either electrum or Multibit.

Well it depends on yourself Wink

do you still like using blockchain ?
If you do then continue using it
If you don't want to use them
Don't worry,there are many alternatives than Blockchain like xapo,coinbase,hive Wink

But i wouldn't recommend to keep using blockchain Roll Eyes

Make a new wallet account somewhere and move your funds from blockchain to that new wallet Roll Eyes

I can't see why you cannot continue to use blockchain.info wallet and another one in parallel. Backup your private keys on blockchain.info wallet and import them into another client or another web wallet. You then have control of the same addresses from two different clients. You continue to use blockchain.info wallet when it's up and use the alternate when it's down.

What you should do now is to backup your keys. Once you have the keys and do not create new addresses, you are save.

I wouldn't use blockchain.info service for anything that isn't spare change. I still prefer Core for your main amount of Bitcoins or a paper wallet with encryption, and then if you want to have some "cigarette and coffee" type of spare change money you can put it on the Mycellium wallet in your Android or whatever.

If you use still use their wallet, you better make a backup now.
So, you can access your bitcoin using other wallet if blockchain.info is down or you decided to use other wallet.

Personally, i recommend you to stop use blockchain.info wallet & use other wallet such as Electrum for Windows or Mycelium for Android, both of them are good wallets.
For block explorer function, you can use blocktrail as alternative

Thank you for your recommondations! I will download an wallet for android, but is that less secure than a windows wallet?

Technically no. Both are open sourced and has no vulnerability as of now. The worst case was probably the 2013 RNG incident that affected almost all of the wallets. It allowed for the creation of transactions with repeated 'R' values, allowing the private key to be less secure. There is no indications that it would happen again. I would recommend you to go with Electrum as your primary wallet and Mycelium as your secondary daily wallet.

I thought if blockchain would go offline and i have no backup right now. So then I lose all my btc right?
Anyways, I have downloaded blocktrail and will use it in the future, also I have send a backup to my email.

Thanks for your help!
