Ok, a bit off-topic, but I have a few facts to consider:

The first two depend a bit on which country you live in but in more and more countries you have either:
- Money printing by central bank reducing the value of your cash every day
- Negative interest rates on your bank account
- It is not that easy to open a bank account for people in some countries.

Besides the above over time assuming more acceptance of Bitcoin and NuBits it is also possible to just do without a bank account and its fees in any country. No 3rd party is required to transfer money with Bitcoin and NuBits.
