That's a great idea but i'm wondering how can i withdraw that stored bitcon if i want 
. Because i also want to store bitcoin for long term soon because now i'm collecting and saving bitcoins as much as i can. I hope i get a reply 
. Because i never tried any kind of cold storage so i'm confused 
.
Blockchain.info atleast have option to import bitcoin address through private key to your wallet. Check the option in imported addresses page inside blockchain.info wallet, but you shouldn't import private key unless you like to send coin from that address. .
