it is entirely possible for the next financial crisis to result in a surge of interest and demand in cryptocurrencies, for the very same reasons that gold acts as a safe haven in times of economic, social and political turmoil.
Defining crypto-currencies as safe-heaven looks like a little bit overkill. But I am sure people will distribute more assets into the ecosystem in case of any big financial crisis.
I agree. There is no safe-heaven and nothing is black and white. Every asset has its features and every investor needs to find the portfolio that best matches her/his values.
