Are my bitcoins safe in online wallet
www.blockchain.info for what happens on August 1?
I have my private keys & my account is fully secured.
I really need to know this

I've heard it's better to actually have a software or hardware wallet rather than an online one. If you have either of those you will always have 100% control over your bitcoin. If the blockchain.info site were to go down you will probably lose access to your coins. Better safe than sorry
