I think lots of the reason why speculators have jumped in and out of various coins is because in the past three years so many coins have crashed and burned. Do people remember the "country coins" like Aurora which were supposed to save Iceland? And look what happened to poor Doge when a scammer tried to take hold of their community.

I think investors have been burned so much that when they are In profit they cash in quickly, lest the profit melt away.
