government regulation may come before 2020 for many countries anround the world and if so this will wipe a lot of the altcoin market...this will be a good thing in the longer term as the market won't be as diversified across so many sh##tcoins. less scammy ico's also.
Or bad... because it will reduce innovation and it will ve harder to raise capital for new projects leading to more security but less agility.
if there is a reduction of altcoin market it will affect the fate of crypto, the reduction of the market is very influential on investors and also the development of crypto will weaken
