It is imaginary in that you can't sense it. It emerges from computer code as an imaginary abstraction.

It has no object of value or beauty. Its is a function, but not a thing which functions. It is a function without a form, yet generates a sense of ownership and value.

It has proven that value is not intrinsic to material, but a conceptual and emotional artifact. It effectively captures the very essence of value - the underlying function than generates value itself.

It gains value and loses value - spiking up and crashing down - but the underlying function of value generation is so concise that over time is increasingly treasured at a phenomenal rate - regardless of it being entirely unnecessary, let alone completely intangible.
