I realize I used to be a bit paranoid: I only look at on-chain data, thinking that if the data is written there, it won't be wrong.

As a result, when the market suddenly moves, I can't hold my spot positions and want to run, and I try to "improve efficiency" with contracts, but in the end, the efficiency leads to liquidation… Basically, it's because I didn't tier my positions, and my mentality collapsed first.

Now I tell myself a straightforward truth: don't let any single position be so large that you need to watch the market constantly to prevent it from falling.
Treat spot as slow money, split it into several parts, set acceptable stop-loss/ take-profit levels;
If you really want to play with contracts, that's fine, but just remember "losing doesn't affect my sleep," and don't pretend to be a hero with leverage.

Recently, the funding rate has been extreme, and in the group, there's again debate about whether to reverse or continue squeezing the bubble.
My approach is very simple: don't guess the plot, first reduce your position so that the funding rate and volatility won't crush you…
That's how I start.
