Martyn Lucas is a high-output English-language stocks-and-crypto creator who runs the "Martyn Lucas Investor" YouTube channel along with a secondary channel, "Martyn Lucas Investor EXTRA." Since launching in June 2021 the main channel has grown past 110,000 subscribers on an unusually heavy schedule of several videos per week, mixing stock-market and crypto coverage with a marked tilt toward XRP and Bitcoin, and a programming style built around live market opens and news reactions.

His format leans on real-time, high-frequency commentary rather than long-form deep dives, and the channel features regular contributors such as Sensei and Vaz who handle technical analysis and emerging-industry coverage. Alongside the main channel he runs the EXTRA feed for more behind-the-scenes content and points his audience to his own site for further material. His audience skews toward retail investors following fast-moving XRP and mainstream-crypto narratives.
