The investment products emerge in the market to earn the difference of profit in the space of currency appreciation. As the bull market peaked, bitcoin prices gradually fell. As a new thing, the lack of the substantial economic support, and the price fluctuations are inevitable. To avoid risk whenever possible, we propose an online reinforcement learning model-Sarsa (State-Action-Reward-State-Action). The model has the characteristics of online learning, sample small batch data from the past. At the same time, it also has the characteristics of intensive learning, which can try to explore in the past experiences, so as to learn to avoid risks and improve the ability of investment efficiency. we compare the our Sarsa model with the latest-based LSTM portfolio model. This experiment proves that the model has minimum regret value and small sensitivity to the proportion of transaction commission.
