Contract players, use small positions with moderate leverage to trade, focusing on shorting at highs as the main strategy. Successfully navigating trades from this year to next is just a matter of earning more or less. "Bottom fishing" is essentially short-term, and fundamentally it is "short long". One cannot have too much of a grand vision; the situation can either lead to all gains being given back or gains turning into losses. Because the overall trend is downward, it's like standing on a treadmill; the faster the treadmill goes, the faster you need to run. If you slow down, you will fall. The logic of going long during a bear transition is just like this.
