Last year i was pretty active in the LISK project and one of the early adopter (and a whale, he had 400 btc) decide to leave the project, he dump all his coins in a single blow which made the price go down 40% (it was on poloniex and bittrex, about 30-50 btc of daily volume on average). He then explain that he didn't believe in the project anymore and wanted to invest himself somewhere else. Of course at that time it hurt the project and the price went bearish for quite a long time. But you need to put everything in perspective now the project is strongly alive and kick ass and it's now in the top 15 crypto standing at a 700M$ marketcap (it was around 12M$ at its bottom).
So you need to put EVERYTHING in perspective and invest yourself in what you believe, it's totaly ok to leave or to stay as long as you take those decisions for yourself.
Stay true to yourself!
Very good comments, supertee made his contribution to the community and the dev team treated him pretty well. He dumped 18000+ ONIONs which is an excellent return for what he did. Unfortunately he will miss the incoming boom and rise of the coin. To the best, this is a day-trading and not an investment. With such a good dev team and community, this coin has a long and beautiful way to go, the investment return will be much higher than day trading
