## Fungibility Bias

Fungibility bias is a cognitive error where individuals fail to recognize that all units of a currency or asset are interchangeable and have the same value. In the context of mental accounting, this leads to the irrational treatment of capital based on its origin or purpose.

For example, a trader might be unwilling to use funds from a long-term holding to cover a margin call, even if that is the most logical financial decision. This failure to treat capital as fungible prevents the optimization of resources.

In crypto, where different tokens and assets have different liquidity profiles, this bias can be particularly costly. It can lead to unnecessary borrowing or liquidation because the trader is compartmentalizing their assets.

Overcoming fungibility bias is essential for effective portfolio management and capital efficiency. It requires a mindset shift that views all assets as part of a single, integrated portfolio.

By treating all capital as fungible, traders can make decisions that are truly in their best interest, regardless of the historical or emotional context of the funds.
