JD and what Else, Fintech Legal Counsel

Hi, I’m attending a non-ABA JD program and I can add on various certificates or one year degrees, or the MBA in AI product dev by Udacity, to boost my career prospects. I’m really interested in finance and technology. What are the best add-ons for fintech or tech legal counsel? Are those fields too competitive and narrow to bet a lot of time and money on with only non-ABA schooling? Thank you
