## Constant Proportion Portfolio Insurance

Constant Proportion Portfolio Insurance (CPPI) is a dynamic asset allocation strategy that provides a floor for a portfolio's value while still allowing for upside participation. It works by maintaining a ratio between a risky asset and a risk-free asset, adjusting the exposure to the risky asset based on the distance from the floor.

As the portfolio value rises, exposure to the risky asset increases; as it falls, exposure decreases to protect the floor. In crypto, CPPI can be used to manage downside risk while capturing the explosive growth potential of the market.

It requires disciplined execution and careful management of the 'cushion' between the current value and the floor.
