nice work. was andy already a contributor to the site prior to the publication?
No, Andy is a new contributor to the site. Personally, I like his take on derivatives, and the piece in a brief but concise manner. He'll be churning out more content.
Personally I can see the rise of derivatives in general, for crypto it is more apparent this year, we can see many new exchanges popping up since late last year to do futures etc. Even major exchanges like Kraken, Bibox etc are also starting to do futures. Definitely a trend not to be ignored
