Not all coins get dumped when reached exchanges. My friend had regret when she sold the full amount of her bounty token. When listed in exchanges suddenly got a lower price but partnerships came to that project and it gradually increase up to now. She had learned, she saw the potential of the project to increase its value, next time she will patiently wait or hold and will not sell the whole amount. Communication and peace of mind is important.
Our own mistakes will really give us good lesson so save it for the next time around.Holding demands more patience and understanding about the nature of crypto,so if you have potential coins to hold,learn to love them for longer investment.In time they will also give you good returns.Just hold them patiently and as much as possible,stay away from panic selling because it will only cause you more losses.
