You can depend your life on Bitcoin that is why Bitcoin is referred to as decentralized and independent!
I'm sure whatever angle to that statement you made was informed by a personal experience of yours. However, I'm of the opinion that no one should place their life consequent on anything; not even on Bitcoin. Yes, it may be decentralized and all that but that isn't the only thing to life. Bitcoin, despite its accolades, is still unstable and volatile. It seems the most safe of all cryptos but that isn't to say one shouldn't be precautions while dealing in it. There are many who won't even talk highly and in good light about Bitcoin till date. Everyone's perspective isn't the same on Bitcoin. Many bemoan their losses while few glory in it.
