Valhalla, in crypto slang, is a mock-heroic name for the reward that committed holders imagine waiting for them at the end of a long ride. In Norse mythology Valhalla is the great hall where warriors who died bravely in battle feast with the god Odin. Crypto communities borrowed the image in phrases such as "see you in Valhalla", used to cheer on fellow holders through falling prices or to celebrate holding through a crash. It belongs to the same family of jokes as to the moon and when Lambo, and to the culture of HODL and diamond hands. The phrase is meant as humour and group loyalty, not a forecast, and the warrior image can make heavy losses sound noble rather than costly.
