A careful observation reveals that the operational teams and Twitter accounts of some leading exchanges are likely run by the same group of people. The tactics are obvious: when their holdings experience a dip, they quickly list a few coins and flood Twitter with aggressive promotions, creating a buzz in the community every day. With this combination of tactics, retail investors are the ones who get caught. To put it bluntly, this is exploiting information asymmetry to induce people to buy into projects that are doomed to fail. This practice is really disgraceful.
