"Big man"

I was lucky enough to stumble across this person's Telegram channel, and after delving into it, I realized that he and his community work in highly specialized fields. I later had the opportunity to chat with him and get to know him better. He has interesting ideas and knowledge in the world of cryptocurrency that he wants to apply. He tries to find the most unpopular areas and extract maximum profit from them. I'm interested in his thinking, so I try to pay attention to the areas he emphasizes and recommends.
