At the expense of safety, I agree with you, but that relates to the preservation of the values, here I have a question. Gold is valued for thousands of years ago and is now valued. I am sure that this will continue. And what will be with bitcoin?
It remains to be seen whether bitcoin will be adopted as a mainstream currency, however banks are gearing up to implement the technology behind it (blockchain) as we speak:

I guess it all comes down to the consumer; if they get on board with Bitcoin (which would probably require greater price stability), there's no question bitcoin will be much bigger than it is now.
