Dear Hussain,

Thank you for reading my work and thank you for taking the time to share the list of HFTs and quants which are active in the cryptocurrency space.

To be sure, HFT as I have narrowly defined it, would necessarily exclude cryptocurrency exchanges which today simply do not have the infrastructure capable of supporting the speeds that are achievable on the New York Stock Exchange.

That having been said, as a firm we have appreciated direct access to the APIs of cryptocurrency exchanges as well as the ability to run our own trading programs on these exchanges directly, a privilege extended only to a select few in traditional financial markets.

Yours,

Patrick
