Generally, lots of discussion whether this disruptive technology should be regulated.

There was an American saying that the ecosystem self-regulates itself.  There's an English gent wanting regulation focusing mostly on preventing financial crimes.  There was also what looks like a transvestite (not judging) giving good insight on the blockchain, and its transparency indicating how cash is more apt for money laundering and terrorism than digital currency.  One person asked if it's possible to confiscate digital currencies in case of money laundering, answered by what seemed to be a Portuguese speaker whom spoke in his native language.  French woman addressed financial transparency and how blockchain adoption would serves as a tool vs. obscurity for centralized systems. 

Overall, the consensus thus far seems to be on the fence (sit and watch).
