Reasons for me is,
1. The work on scaling issues
The token's market dominance stood at about 40 percent as of Wednesday. By my estimates, however, it's clear bitcoin's market dominance should return to 75 percent of the entire space.
2. Large scale and more legitimate ICOs
Like last year, initial coin offerings (ICOs) will impact the ethereum network because ICOs usually require plenty of ether. That will buttress the demand for the platform's digital coin. More legitimate ICOs will lead to greater interest in ether as we are already seeing with the billion-dollar ICO of messaging app provider Telegram and that of Kodak.
3. Regulation
We saw something similar when Japan started regulating bitcoin. The market dropped initially, but it rose eventually. Ditto in Australia.
4. A lot of execution and usability
This would burnish the reputation of cryptocurrencies, with more and more companies trusting them. The firms that execute well this year will stand out and create a survivorship bias where a few companies thrive and others fail, but people focus on the winners and ignore the losers.
5. Institutional investors
If you combine those factors, the market's upside potential could rise to up to seven or eight times the present levels. While this might not be as much of a multiple as what we saw in 2017, it is much higher in absolute terms. That could make 2018 the most successful year in crypto ever. Additionally, the growth might not be based so much on hype or hope as it would be on solid foundations.
