Yes. If you had to make a dozen eggs secure, would you tend to put them all in the same basket or place them at different locations?
Firstly, the design of distributed technologies makes them a better response to security issues, because not all the data is in the same location.
Second, there has been a lot of conversation about how quantum computers might be able to crack blockchain technology. Until proven otherwise, and I'm talking about Bitcoin here, many believe that the difficulty involved in proof of work, because the structure is changing all the time by those using the data, is such that it can be protected and resist a quantum attack.
I would say that blockchain technology is much more secure than putting all your eggs in the same basket, by which I mean a central database somewhere in the cloud.
