I think it's really difficult to predict how the market will evolve. Basically it's just guessing. Can't look into other peoples head.

In my experience the more people post FUD (same as the hype/ to the moon posts) once the sell or buy power slows down we head into the opposit direction. Sometimes that's so fast we get huge jumps within a couple of minutes. Shorting is quite risky in my opinion.

Therefore i just buy every now and then and hold the coins.
