For those who have been investing in Crypto, What will cause bitcoin to rise in 2019? Or to crash?

As per my vision. Bitcoin may take another high in 2022. Things are changing regarding cryptocurrency. More people are getting involved in this type of investment. Although several countries government has banned this type of investment. But on another hand, big players are looking for a middle way to open the door for safe investment in crypto.

It's mainly speculative with many countries against it and nothing to back up the asset. In the past, cash was backed by gold and now it's by the monetary authority/reserve. Unless there is significant change in stance by large nations, there is unlikely any good improvements
