To the moon Alice!
When someone says that this coin is “headed to the moon” or it’s going to moon, they are referring to the coin having massive increases. A very common phrase is Bitcoin.
It can even be used as a verb like “have you checked the charts? Bitcoin is mooning!”. Meaning Bitcoin is flying up in value as we speak.
Other variations include:
“I hope this coins moons!”
“It’s on a moon mission.”
All mean go up in price A LOT. Proverbially having astronomical gains. Frankly, everyone hopes the coins they chose moon.
