Because they are a competitor? If they would move that much. 5 million coins is 4 billion dollars and that is tripple the daily traffic. That will cause big changes very clearly. More like 3x80=$240-480 difference potentially. 5-10% is not a small amount. And now I haven't even added in the sheep effect that they may cause so move to even $100-200 per Ethereum coin. Plus they are slower in speed compared to EOS goal. Currently we are using a platform that Dan helped create so clearly he is a genius so I wouldn't underestimate his future projects!
