Was he being jealous?

I know this guy who works at a store as a cashier we met years ago. Whenever I see him we talk. And we hooked up and had sex once. Recently I started talking to another guy about Bitcoin who works there and he heard me talking to him. So I saw the first guy who I gave money to recently And I asked him why he doesn’t want to keep it he said it’s too much. He said maybe I can use it to buy Bitcoin. And when I told him he was so sexy he said oh stop and walked away.

I just don’t get it.
