A lot of Altcoins are based on ICOs. Something that is very discouraged by Governments and Control Authorities. They are going to come hard at it. China, South Korea has already banned it. Japan, Russia, Estonia, Australia, India, United Kingdom, Singapore are likely to do so too or regulate it. US SEC already considered it as security.

Frauds like DRC World and Recoin and what not. Companies from across the world have raised more than $1.8 billion this year via ICOs literally with nothing on ground.

And more than that, most of the altcoins are not catching up on their Roadmaps such as Monaco, Stratis. Stratis is down and out and I am stuck with it :( Monaco was supposed to announce their card approval in Sept, nothing so far. And again, I am stuck with it too :(

In short, a lot of uncertainty. Stay in cash.
