Where is welcome used?

Can you clarify the context in which the phrase "where is welcome used?" is being asked? However, if I were to interpret this question broadly, I'd say that the word "welcome" is commonly used in various situations where people are being greeted, made to feel accepted or valued, or invited to participate. For instance, in a business setting, "welcome" might be used by a receptionist to greet customers as they enter the building. In a social context, friends might say "welcome" to each other when one arrives at a gathering. And in the world of cryptocurrency and finance, the term "welcome" could potentially be used to express openness to new investors, users, or partners, or to signify a positive reception of new ideas or technologies. So, in summary, "welcome" is used wherever people want to express a sense of hospitality, acceptance, or inclusion.
