I think the key benefit of bitcoin here is that you have a choice as to who holds your bitcoin for you, as opposed to there being only one option: storing your money with a bank. You can store bitcoin with an online wallet or on your home computer, and there are risks in both cases. E.g. if you are afraid of getting hacked, or accidentally destroying your own keys (common enough to be a real concern), you may determine that storing your bitcoin with a service like Coinbase is better for you personally in your specific context. The advantage of bitcoin is being able to have that option, not that it's always necessarily better to store bitcoin on your own.
