The high-level resistance I was watching earlier finally gave an answer today. $OPG didn't drop suddenly; the real change had already appeared when the rebound weakened, but many just didn't catch on. At that time, I noted that the key resistance level was repeatedly tested and failed, with price quickly getting knocked back each time it rose—indicating insufficient buying power there. I observed the shift before the signal came out, so I went short around 0.2047, without chasing a price that had already fallen too far. Now it's at 0.1185, with a return of +829.14%, and the trend is clearly extending. The most critical point is that during the decline, the rebound strength was very weak, meaning this isn't just a simple shakeout—the short-term rhythm has already been taken over by bears. At this level, don't get too carried away after taking profits. Take 80% off the table first, and keep the remaining 20% with a protective stop to see if there's further room to run. If you missed it, don't rush, and definitely don't chase after a drop. The market moves every day—wait for the next opportunity. $BTC $ETH
