first, you said you want to find out your bc.info priv keys and transfer your fund to coinbase
if you want to transfer (send) fund, you don't need to extract you priv keys... just send them from your bc.info account
second, you
"hacked and imported 69 btc" 
but you need to get the private key?
really? or you just downloaded an encrypted wallet? a list of addresses with balance? or what...
third, now you said only have 0.0004 btc

where is the 69 btc you mentioned earlier?
your posts are contradicting one another,
I'm confused what exactly your situation and what are you trying to accomplish?
Quite weird indeed.
He then goes on to plug his "Bitcoin adder" several times,
https://bitcoinxadder.com/ (which is obviously a scam for anyone wondering.) which makes me suspect that he is just trolling.
It's already a scam... Also, do you really think that the top 100 adresses would still hold so much balance if there actually was an exploit? Not only would these wallets be hacked already, the price of bitcoin would also dramatically decrease... I'm really confused whether you are pushing some sort of ponzi scheme for your own profit, or if you're actually thinking that there's some magic bitcoin generator...
Most of you think coinbase is insecure but i think it has authentication so it's better than blockchain tbh, now i got like 0.0004 btc or something and after i add i will be getting 0.5 btc daily i wanna keep it secure to sell it in a later period , that is why i think coinbase is a secure wallet and better than blockchain.
Are you seriously this naive? ( Or is this your site?) Might aswell give me your money...
