Your savings however, if you wanted it safer you have to put in the bank as only investment should be put in the blockchain.
It's still better to have fiat savings rather than bitcoin alone since internet are not present all the times. So just in case you need in an emergency you don't need to log on with your device just to execute withdrawals of your coins. And besides, withdrawals of bitcoin are not that instant in most of the cases per country.
