The risk-reward ratio of #风险回报比 is an important concept in the field of financial investment, used to measure the relationship between the potential risks and returns of an investment.

Formally, it is the ratio of the maximum possible loss (risk) in an investment to the expected gain (return). For example, if you expect to lose 1000 yuan on an investment while anticipating a profit of 5000 yuan, the risk-reward ratio would be 1000 ÷ 5000 = 0.2.

Generally speaking, the lower the risk-reward ratio, the more attractive the investment, as it implies that a lower risk might yield a higher return. However, in actual investments, cryptocurrencies like Bitcoin have extremely volatile markets, making it difficult to accurately estimate the risk-reward ratio, and different investors have varying capacities for risk and expectations for returns.
