With bitcoin, we are our own bank. So the safety and security of our funds lies within us, our capability to keep and store our bitcoin privately and securely, which we cannot expect from banks to do it with fiat.

Furthermore, bitcoin is decentralized, so it has nothing to do with big names and companies that could back-up bitcoin but the control is given to us solely. This is the best chance for us to accumulate maximum amount without the interruption of other group or entity, unlike fiat that is monitored by the government and banks.
