Is it okay to just say welcome?

I'm curious, in the world of cryptocurrency and finance, where every detail matters, is it truly sufficient to simply say "welcome" to a client or a potential investor? Wouldn't a more personalized and professional greeting, tailored to the individual's interests and the nature of our business, better reflect the level of expertise and attention we strive to provide in this industry? In a field where trust and reputation are paramount, doesn't a thoughtful and engaging introduction set a stronger foundation for a fruitful relationship?
