There are many factors that affect price in the young and often illiquid crypto markets. These include deliberate disinformation, rumors, speculation, outright manipulation and inexperienced investors making superficial decisions to buy and sell at all the wrong times based on what they see the herd doing.
This is all fine, but if you are
investing, not gambling, then you will be most successful if you do your homework and thoroughly understand the leadership, developers, technology, businesses, and supporting community behind each investment.
Predicting where a rocket will be at sometime in the future does not have much to do with its current position. The more derivatives you look at (velocity, acceleration, etc.) and the better understanding of outside forces (like thrust and drag and gravity and bugs on the windshield) you have, the better your prediction will be.
Market cap = position which is a imperfect
lagging indicator reflecting what real and imaginary forces have acted on an asset
in the past. There is no substitute for doing your homework to understanding the forces that are currently acting on the asset you are considering.
Most amateur FUD is just bugs on the windshield.
Knowledge and understanding are the ultimate proof of work.
