# Crypto assets do not have a verifiable valuation model
Crypto tokens have no reliable [valuation method](../concepts/valuation-model.md). It is not possible to develop a theoretical [value](../concepts/value.md) for a crypto token because there is no demand curve generated by a [use case](../concepts/use-value.md) or any [income or cashflows](../concepts/income-cashflows.md) associated with the [security](../concepts/security.md). Crypto tokens have a strictly zero [fundamental value](../concepts/fundamental-value.md) and a [present-value](../concepts/present-value.md) of zero.

Instead the price of a crypto asset swings about wildly depending on the whims of fluctuating demand, random sentiment and market mania of the larger crypto [bubble](../concepts/bubble.md). Crypto assets are a manifestation of the [greater fool theory](../concepts/greater-fool-theory.md) and the price of a crypto asset is defined simply by what people believe the next "fool" will pay for it.

Models such as "Stock To Flow" have shown no predictive power to explain the [price formation](../concepts/price-formation.md) of assets like [bitcoin](../concepts/bitcoin.md) on long time scales. These models have no rigorous foundations based on any mainstream economics.
 
Other products in [bubble](../concepts/bubble.md) such as tulips or beanie babies have exhibited similar market structure to crypto tokens but on smaller scales.
