Crypto currency removing all the problem of modern banking or fiat payment and having the potential to be future currency it no longer a news and the IMF also advise the Central Banks and the government about it that's why we see alot of institutional investors accumulating cryptocurrency.
Still crypto account can still be hack if human errors are not avoided.

That's right, local media in my country say many banks are adopting blockchain technology. Although only technology but this is the beginning. Although I am not sure for the next 10-20 years we will not be able to use it as a legal tender. Due to differences in understanding of technology in several countries in the world, there are very big differences.
I think that in that money paper and metal currencies will still dominate usage around the world. Regarding vulnerabilities in my opinion all technologies have their weaknesses, nothing is perfect. We as users can only do prevention from crime through the loopholes of weakness. And I'm sure it will continue to grow to fix that weakness.
