Big drop in the morning means to increase positions, big rise in the morning means to reduce positions.

Big rise in the afternoon only means to reduce positions, big drop in the afternoon means to buy the next day.

Do not sell coins when there is a drop in the morning, increase positions at a low (T+0).

Do not chase prices when there is a rise in the afternoon, reduce positions at a high (T+1).

For morning rises, watch at ten o'clock; for afternoon rises, watch at two o'clock. Sell at the highest point. If the coin is strong, seal at ten o'clock; if the coin is not strong, seal at two o'clock. Control positions without taking risks; rolling operations are the best strategy.

Do not short in a bull market, do not long in a bear market.

Do not kill dips in a bull market, do not chase rises in a bear market.
