Blockchain.info is generally as safe as other online wallets. Good for small amounts that can be accessed from anywhere.
You should use an offline wallet for larger amounts though.
Ever since I ventured into the bitcoin world, i've been using the blockchain.info online wallet and it hasn't really been a pleasant ride. I have had several cases of my bitcoin being transferred to the wrong address. My most recent issue is my bitcoin simply vanishing... Not a trace! Not even in my transaction history.
I try to keep all my passwords hidden, enabled 2-factor authentication, and this still happens.
Is there something i'm doing wrong or is blockchain.info not just a secure wallet.
Has anybody experienced anything similar?
I've actually never had any problems with the Blockchain wallet, but I'm generally told that it's not a very good choice due to frequent bugs and issues.
If you're sending to the wrong address, that's extremely unlikely to be Blockchain's fault and you might have malware. If you do have malware, I would suggest running several virus checks before you download a software wallet, because Bitcoin in software wallets can be stolen by malware pretty easily.
When you know that you're safe, you should note that Bitcoin Core is pretty hard to download - you'll require a lot of disk space. It's the official wallet run by the current development team and you're essentially downloading the entire blockchain to run it, which is called a full node. The Electrum wallet is better for convenience and probably will be best in your case.
This, there is some malware that modifies your clipboard to a different address when you paste.
