Regulating Cryptocurrency Markets

In traditional exchange regulation, one of the main things that happens is trade reporting and letting others in the trading ecosystem as well as the regulator know what's happening. In the crypto space, particularly with respected decentralized exchanges, all of that information is already available and public. So to the extent that we've established that there are a lot of different ways for people to get at information, where do you guys draw the line about where the feds have a legitimate claim to be able to step in here?
