when i was in college, i preferred to buy udemy courses for topics i wanted to learn - in my mind, a paid course with high rating had a higher chance of quality content vs free playlists on youtube these courses were mostly around upskilling for job interviews - so courses like "introduction to corporate finance" and "data structures and algorithms" its surprising how there are only two paid + well known (non trading) courses made by CT natives i.e. shefi and safary's marketing course huge potential imo for a working professional in crypto to launch a "Crypto 101" paid course on udemy as the industry matures and gets more interest from college students to join in
