As long as your private keys are safe your bitcoin is safe. Because it is merely impossible to breach into another's wallet without knowing private keys. So keep your private keys safe. Best use offline wallet to ensure security.
Yes I agree with you. Bitcoin is not totally safe because your account can be hack by anyone but you can protect your account from hackers by keeping it secure and do not share your private or personal information to others. Always make sure that no one can bring you down.
