Talk about one key point to learn during a bull run: Position management.

For short-term trading, it's important to set stop-loss and take-profit levels. Withdraw when there's risk, and learn to run when there's profit.
In the long run, you need to set goals and expectations, and consider what height you think the project might reach, especially if you have low-cost positions. The most challenging aspect of a long-term strategy is the mindset, because it is impossible to keep pushing the market up; each time the price rises, you need to shake out the weak hands and those chasing the high in order to continue moving forward. Can you remain firm in your investment strategy?
There is a psychological suggestion: for example, if you bought XRP for 0.5 dollars and sold it for 1 dollar, and then it rose to 2 dollars, even if you think it can go up further, you wouldn't want to get on board.
Invest short-term and long-term separately.
In the short term, remember not to play long positions. If you fall and don't know how to stop-loss, you'll end up being trapped, which is very uncomfortable. You are originally speculating, not investing for value; if it drops too much, you won't average down, you'll just cut your losses.
Don't turn long-term plays into short-term trades. You could have reached a higher level, but instead, you sold your position as soon as there was a small pump, and you ran away at the slightest pullback. You sold XRP at a cost of $1 and can never buy it back. So, you must learn to sell in batches.
In the secondary market, a bull run will always drive the price up. So, maintain your own investment rhythm and lay the groundwork for long-term positions. Short-term trading must focus on hotspots.
Positions are separated, 7 long and 3 short. Short-term positions may yield several times the profit when encountering hot market trends. Even in a bull run, it is essential to maintain the mindset of never being fully invested. Being fully invested is very passive.
Trade hotspots in the short term, and set good stop-loss and take-profit levels. For long-term coins, adhere to the principle of doubling your investment to recover the principal, with the determination to hold profits for over a year. Some say I can choose not to double my investment to recover the principal, but you need to cultivate a stronger mindset, especially since it's normal for many coins to experience significant pullbacks after a big rally. Doubling your investment to recover the principal allows you to continue searching for good targets or to withdraw.
Clear thinking can make money in a bull run. In a bull run, pursue ambiguous positions.
For example, fearing to miss out, thinking that the pullback is almost over, or being at a relatively low Position, but also fearing a waterfall, one might buy a small Position first to feel it out, being brave enough to get stuck. Only after getting stuck can one continue to add to the Position; otherwise, one might never get on the bus.
