Bitcoin 1.0 probably won't happen in our lifetime.
I think it will happen in the next 15 years. I think bitcoin needs to achieve the following goals for it to happen:
- Throughput that scales and that can exceeds Visa transactions
- Better anonymity
- Low cost per transaction probably less than 0.02$
- Quantum computer resistant
- Mining solution for Bitcoin going forward without block reward
I don't think it is possible to create a Quantum computing resistant bitcoin in 15 years because quantum computers are not going to arrive that soon, while there are encryption algorithms which in theory could not even be solved by quantum computers, we will not be able to determine how much powerful a quantum computer actually is until a fully functional model is put to test.
