I will suggest that dont put all your money to bitcoin and some of your money must be secured in your bank account for emergency purposes. Any Bank will always give a guarantee their customer that they will secure their money no matter what happened.
In term of solely for security , BTC is indeed a better option ( Im a fan of securing my own belongings ) if you know how to do it properly but in term of solely investment , I would say that BTC is a good but as I said dont put all your money in ine basket only,  put some of your money in safe deposits as an investment
