Cryptodictionary: To the Moon
This expression is used to describe a situation where a certain coin is experiencing such a bull run that it is literally breaking the charts. Like, for instance, the early start of YFI when it went from $1 to around $40 in a matter of weeks. You would say, it was going to the moon.
You would often hear it as a wish or even a toast for a starting project or a hopeful exclamation of an investor seeing the early stages of a bull trend for a favored cryptocurrency.
