I think there will continue to be a rapidly growing number of coins with no clear leader. Regions and countries will have coins that have become popular with real uses as trading tools, with government's trying to control them. At some point there will be a global winner that will be nothing but a fiat currency replacement, controlled and taxed. I wouldn't be surprised to see governments banning crypto coins altogether other than their chosen platforms in their quest to keep us all under control. Just how I see the next 10 years of crypto currency playing out.
