How to Be Fluent in Esperanto

I never really noticed when I became fluent like it's hard to say. The moment I realized that I was like 100% fluent was when I was having a conversation in Esperanto with a Chinese Esperanto speaker and we're talking about cryptocurrencies, he says. "That's giving me goosebumps because I remember that feeling from French" He also talks about his love of Portuguese which he now speaks with his wife every day.
