It's a grind. He buys names with low liquidity and he's basically a whale buying like $200 worth and it impacts the price. He works in a team, he'll warn people when he sells, price will dump and it's usually a buyable dip.
He spends a lot of time on it and for an hourly rate, it's not great. He says it's fun for him though.
If you're actually serious I'll ask him for some resources on how he does it and where he got his research. His hit rate is really good. Tech guy, works for Square/block or whatever the fuck. He's building a bot too, that's when I'd be interested. I prefer passive income.
