This is what everyone should know. Price dump is inevitable because its unhealthy for price to keep going up. Traders and investors will take profit which will cause price dump not minding how good the project. But a good project will rise with development and demand.
It's not the traders who have been taking the profit but the early investors who have been dumping it so crazy. When a coin already traded above the ico price and early investors will be making the price of coins to go back to the ico price again. The development needs time while the dump can happen easily and anytime.
