When an asset decreases in value your net worth will not change because there was no cash involved?

When an asset decreases in value, your net worth does reflect this change, as net worth is calculated by subtracting total liabilities from total assets. Even if no cash is involved in the decrease, the reduced value of the asset impacts your overall financial position. However, this change in value is considered a paper loss until the asset is sold or otherwise liquidated. Therefore, while you may not experience an immediate cash impact, your net worth is indeed affected by the asset's decreased value.
