No offense but I'd suggest you to use traditional wallets (e.g. blockchain.info old web wallet) ATM. After educating yourself, you can go for modern wallets for sure IMO.
Thank you for that such kind of informations. Yeah I'm still using blockchain.info and I like their new update most especially the security features.
These are two different things. I linked a guide how to export private keys from the new bc.i (v2) in the OP.
Wow, that's great. Thanks a lot for updating. I'll check it out and get my private keys now.
