I think ethereum is gaining more acceptance among business and that is why we are seeing many icos using it to raise funds from the public. We should not undermined the significant of this in cryptocurrencies development because a particular coins must be adopted for a particular purposes and that is what I see with ethereum and fund raising.
Ethereum smart contract is the cheapest platform so most of the projects are follow the same way and neo also little popular concept in crypto market. Future of cryptocurrencies are improve the technology so some unbelievable new arrivals are occupy the top region. I think bitcoin is always maintain a first position because most of the companies are adopting the Bitcoin so stable marletcap is possible in future.
