Randomness!
There are some super smart guys on this forum who think they can predict coins like LTC due to actual facts. It's almost hilarious if it wasn't so pathetic. The truth is 90% of big moves are irrational and based on intangible human moods and whims.
I've made more money than most simply sticking my finger in the air and testing the mood, often being contrarian rather than following the crowd. But seriously logic is the last thing you want to follow.
Logically thinking is the better way for earning through the price dumps and pumps. Though digital currencies were speculative, at some instances these wereovercome by the acceptance and the circulation happening with the concern token.
