Is my brother being scammed?

I know nothing about crypto or how it works so I want to ask people here if my brother is being scammed.

He wants to buy in to a coin he won’t tell me about. says its a “meme coin” out of argentina or some shit. And that he knows a guy, who knows a guy, who told him to invest at a certain time because he either control’s its price somehow or knows when it’s gonna go up. Sounds way too good to be true.

My brother is a gullible 19 year old so i want the opinion of people here if he’s being scammed or not. Sorry I don’t have more information I’m not a crypto person and I’m just going by what he’s told me.
