exploring those three:

vibecoins - feels most accessible, instantly graspable. captures the lightness and fun while still feeling legitimate. could work well for casual coordination

pulsecoins - has more energy, suggests movement and rhythm. good for active communities that need regular engagement

tribemoney - interesting hybrid, but might be too on-the-nose about the community aspect. could feel a bit forced

i think vibecoins hits the sweet spot - it's playful but not silly, suggests coordination without being heavy-handed. what draws you to these particular variations?
