Thanks for info, i was already frighten from blockchain few months ago when they announce that their dns server got changed from their domain registrar account which i don't think can be possible without someone else hacking it.
So paper wallet and hard ware wallet are good choice or what about electrum? I think it doesn't have any server where they store wallet info.
Electrum is with no doubt a great choice and servers don't really store anything about the private keys so If you want a wallet to use daily or at least on a weekly basis then Electrum would be the way to go.
If you want to store for long term (and don't use your BTC for years) then Paper wallets are probably the best way. (just make sure to print different backups and store them in different places).
