I've read so much about Cambridge Analytica and similar organisations! It's such a fascinating topic how these organisations with power and a broad reach can influence the cognitive behaviour of a complete community of people.

Phenomena like what Cedric says (and wow, both of you are one of a kind in smarts) are OneCoin, Bitconnect. It's interesting how such a massive amount of people can fall into such things, but it's nothing new and has been happening from the beginning of society. I think that most of what is in politics is a macro-view of this phenomenon.

This is one of my areas of study, so forgive my enthusiasm hahaha

If we are to trust the current state of the world as a positive simulation of what tends to happen in a human-run free market, then we can safely assume that there will be many major coins in the future that will be centralised and will have doubtful/controversial features such as Ripple's centralisation and Dash's lack of transparency.
