Who has bought tickets to the moon?

Could you elaborate on the phrase "Who has bought tickets to the moon?" in the context of cryptocurrency and finance? It seems quite metaphorical, suggesting a leap into the unknown or a pursuit of futuristic gains. In this scenario, are we referring to investors who have jumped on board with cutting-edge blockchain projects or perhaps those who have invested heavily in cryptocurrencies, expecting astronomical returns? Or does this phrase carry a deeper meaning, representing a new wave of financiers breaking barriers and aiming for the moon? Clarifying this metaphor would greatly assist in understanding its implications within the crypto and finance landscape.
