BNB misled me! 622 was scared away by a missile strike, now I want to chase but I'm afraid of Bitcoin crashing the market...

As the saying goes, "A single big bullish candle changes three views, a missile destroys everything," this phrase is just too fitting for me. At this moment, my heart is filled with endless regret, truly BNB misled me!
Yesterday I was in a pretty good mood, holding BNB and watching it climb steadily. To be honest, when it previously reached 640, I was as steady as Mount Tai, with no thought of selling, secretly thinking I could catch big gains this wave.
And then? Suddenly in the afternoon, a message about a "missile attack" popped up. At that moment, my old trader PTSD instantly kicked in, with thoughts of "black swan," "liquidity exhaustion," "flash crash." My hands moved faster than my brain, without any hesitation, I immediately closed my position at 622. After closing, I even thought I was quite sharp, feeling I could dodge the big drop and pick up some cheap deals.
And then? The crypto market doesn’t follow the usual geopolitical routines! Today, looking at the chart, BNB’s upward trend is so obvious, I watched it recover all the territory it lost yesterday, even pushing forward. This feeling is like growing a cabbage with hard work, about to harvest, but a passing wild boar startled me, and I pulled out the cabbage and threw it to the boar.
What hurts me most now is not just missing the opportunity, but falling into a deadlock of dilemma.
Looking at its current trend, FOMO is pulling me madly, I want to rush in and buy back immediately. But! Just a glance at Bitcoin’s (BTC) trend makes me instantly chicken out. Bitcoin now is like an old man walking a tightrope at a high position, unsteady, ready to fall with a big red candle waterfall at any moment. If I get impulsive and chase BNB now, and Bitcoin drags the market down, it’s classic "chasing the top at the mountain peak," turning a profitable position into a high-level standstill. That would make me a pure fool.
This move really taught me a lesson: when the technical trend is good, don’t be easily shaken off by sudden news. But I understand the principle, it’s just too hard to practice in real trading.
Brothers, give me some advice. This trend is clearly good, but with Bitcoin hanging over the market like a sword, how should I handle it? Should I grit my teeth and build a tiny bottom position to test the waters, or just hold back and wait for a full correction? Waiting online, it’s urgent, don’t scold me, I already scolded myself eight hundred times last night…$BNB $BTC ‌ ‌
