It's part of the game and is actually beneficial in my eyes. If everyone was holding Stratis at the ICO price, it would be hard for it to rise since everyone is different and will take their profits at different times. The higher the average price of your holdings, the higher the price you'll wait until you sell it for a profit. Unless you just straight out sell Stratis at a loss, then you should just forget about cryptos and invest in bonds. It is good that the weak hands leave early so that we can go to the Stratosphere.
Actually they are selling to ..... themselves. Like you said - just part of the game.
