In trading decisions, the reason why one tends to choose to increase positions in profit rather than in loss is rooted in a profound insight into risk and human nature.

If one adds to a losing position, facing two consecutive failed trades can result in a threefold loss of capital. Even if adding to the position is fortunate and successful, human weaknesses often lead individuals to rush to exit when faced with small profits—people tend to blindly hold onto losing positions, while they tend to exit too early when in profit due to risk aversion, ultimately missing out on greater gains.

Conversely, the logic of increasing positions when in profit is more robust: if the market reverses after adding to the position, one only needs to bear the loss of the newly added portion; if the market continues to improve, one can amplify returns through three positions (initial + two additional positions), achieving a multiplication of profits.

This strategy not only avoids the risk accumulation inherent in adding to losing positions but also aligns with the possibility of trend continuation, while better controlling the greed and fear inherent in human nature. It is a rational choice validated by the market.#美国加征关税 #比特币 #以太
