I feel that vitalik created blockchain 2.0, which should be regarded as a milestone in the currency circle. In the world of blockchain, his contribution is second after Satoshi Nakamoto.
As long it would really be beneficial and that really revolutionary then it would really be significant but still nothing can beat out on what that the first do able to achieve.
Yes, he could make that contribution but i dont think that it would really be having the same impression on what Satoshi had done because nothing can beat out the first
even though in terms of technical aspect then it might be something that ahead but support or the community will always look on whose first.
