When did 3E come out?

Can you please provide me with some context regarding the entity or product named "3E"? Without knowing the specifics, it's challenging to accurately answer the question "When did 3E come out?" However, assuming "3E" refers to a particular cryptocurrency, a token, a blockchain platform, or a financial product, I would inquire further by asking: "I'm curious about the launch date of 3E. Could you elaborate on the specific product or service that you're referring to? If 3E is a cryptocurrency, for instance, when was the initial coin offering (ICO) held, or when was the token first made available on exchanges? Alternatively, if it's a blockchain platform or a financial product, when did it first become operational or publicly available?" This approach allows for a more informed and precise response, given the various interpretations "3E" could have in the cryptocurrency and finance landscape.
