My hardest lesson: The cost of ignoring market structure in crypto

I've made plenty of mistakes in crypto, from chasing narratives to letting winners turn into losers, but the one that truly stands out as the most expensive, both financially and emotionally, was ignoring market structure on a significant position. It was during a particularly volatile period for $ETH. I had a decent long position, but the daily chart had painted a clear lower high and lower low, signaling a shift in momentum that I chose to rationalize away. My bias, fueled by hopium and recent success, blinded me to the fact that price was consistently rejecting a key resistance zone that had previously acted as support. Instead of acknowledging the technicals and either reducing exposure or setting a tight stop based on the new market context, I held on, believing in a bounce that never materialized. The subsequent waterfall sell-off liquidated a significant chunk of my capital, a loss that could have been drastically mitigated by simply respecting the established downtrend. The lesson was stark: no matter how strong your conviction, market structure dictates the high-probability moves, and fighting it is a recipe for disaster.
