Which Spanish speaker knowledgable about BCH and cryptocurrencies would you recommend for an interview with an economist?

There is a Spanish libertarian economist that wishes to interview someone regarding Bitcoin and the lightning network. I would like to suggest him to also interview (or maybe set up a debate with) someone that supports BCH and explains how a cryptocurrency can scale.

Who would you say is fit for the task?

The economist is called Juan Ramón Rallo (YouTube), and he produces high-quality content regarding free-market economics, libertarian (classical liberal) philosophy, political analysis, even detailed ancap debates.
