ETH represents their largest competitor. Capitalism is a cut throat game. They hold a massive amount of ETH and are able to attack them by selling it. We shouldn't expect crypto to be any different than the shit on Wallstreet. We shouldn't be surprised when this shit gets crooked and dirty.
Like, Bitfinex and Tether are likely used to launder Columbian drug cartel money
