I think it's not about your nervousness, but because your brain has a hard time translating Indonesian ehehe, so it makes you feel awkward.
But you did it well. It's not easy to tell people especially about blockchain. Slowly, and maybe later with offline events it will be easier for you.
😄 I think so. I find it easier talking offline actually. It's also easier to explain in a language that I understand. I am currently tutoring English and I could see my student's problem in me but it's all reserved haha.
