Last night before bed, I reviewed again why I can't hold onto spot positions and still keep thinking "just hold on a bit longer" with contracts... To put it simply, it's one sentence: don't prove yourself right by holding through the pain.

For spot, I only keep the amount that doesn't affect my sleep even if it drops; the rest I treat as experimental positions for volatility, exit when reached, don't get caught in a fight.
Contracts are even simpler, positions that could blow me up shouldn't be opened in the first place, leverage gets to your head, risk control is just stubbornness.

By the way, a quick rant: recently, when I see large transfers on the chain or hot and cold wallets moving on exchanges, the comment section starts with "smart money is coming/going."
I also love looking at data, but really don't treat addresses like a crystal ball—seeing unusual activity should just remind you: volatility might be coming, don't fill your positions to the max.
Anyway, I now prefer earning less rather than living on luck.
