He stole a mix of few books. 1. Farming Airdrops which isn't risky in general and has high ROI. 2. THE FREE EBOOK THAT I MADE IS CALLED "SMALL GUIDE ON HOW "I" ANALYZE MICROCAPS I INVEST IN" where I haven't disclosed other 90% of stuff i do when i do analysis but just gave a free beginners way on how i do it when market is green for those who are newbies. When market is sideways/red i just farm airdrops to make 100%+ ROI in 4 months. My main paid ebook can't be compared to this book as it's probably the best ebook for MMO out there. He is the one who added the "Make Money" niche to it, as crypto is risky you can do 100x in a day and also -100% in a day depending if you know what you're doing or not.
