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?
