The PNL (Profit and Loss) is an essential metric in the cryptocurrency market, used to calculate an investor's profit or loss. It can be realized (when the position is closed) or unrealized (when the asset is still held). The PNL directly influences profits, as it reflects the price variation of assets and helps traders adjust their strategies. In volatile markets, a positive PNL indicates gains, while a negative one may signal losses. Monitoring the PNL allows for more informed decisions, helping to minimize risks and maximize returns. Tools like CoinStats assist in accurately tracking this metric.
