What is the biggest lesson BTC taught you?

The biggest lesson BTC taught me is that if I plan to hold it for years, the daily chart should not affect my decisions.

I still check charts sometimes and adjust the amount I buy based on the price that day, but I'm not to treat every red or green candle as new information. I care more about liquidity, rates, ETF flows, and whether the long-term reason for holding still makes sense. A 5% drop can make you feel bad, while a big green day can make you feel late. Neither is useful if your timeframe is long.

That has affected how I look at other investments too. I try to separate “is this worth holding/owning?” from “is this a good entry today?”
