What is an example of welcoming?

Can you provide an illustrative example of what constitutes a genuine act of welcoming? I'm seeking a scenario that embodies the essence of hospitality and warmth, one that effectively demonstrates how individuals or organizations can make newcomers feel at ease and valued. Perhaps a scenario where a cryptocurrency exchange greets new users with personalized messages, simplified onboarding processes, and educational resources tailored to their needs, thereby fostering a sense of belonging and trust within the platform's community.
