I am happy to see such cooperation across cryptocurrency exchanges to interdict these heinous crimes. 

Unfortunately, in addition to the beneficial uses, crypto is also leveraged as a means to support criminal acts which undermines legitimacy and the positive moral purpose of this growing technology. The lawful minded users and community of digital currency don’t want criminals to run rampant and are acting in a coordinated effort to track these malicious parties. 

It is great to see such proactive activity by Coinbase, Bitfinex, and others that strengthens the cyberethics of the industry. I hope to see more such grass-roots efforts take hold to reduce the abuse by criminals.
