My most expensive lesson this cycle wasn't a coin, it was impatience. I bought dips in October that looked like bargains and every one of them needed another leg down before it actually bottomed — $BTC is down about 10% in a month, fifth straight red week, and the lesson I keep re-learning is that a level isn't a buy just because it held last time. It needs the flows behind it, and the ETFs just bled $1.28B in a week.

My rule now: buy in pieces, never on one candle, and never with money I'll need before Tuesday's CPI print.

What's the one lesson this market has taught you the hard way — the mistake you won't repeat?
