$GUA 0.3158, a single-day crash of 25%, eating up 20,000 USD worth of my position in one morning — now everyone is asking me if I can hold.

A piercing needle slams down to 0.3100, with a volume of 16.6M still expanding — is this a golden pit or a burial pit? Two voices are fighting in my head; listen for yourselves.
The bullish logic has three points: First, the 0.31-0.32 range is a weekly support from previous high-volume trading area; last August, when it fell to this level, it rebounded 80% directly, so the probability of history repeating is not small. Second, the 16.6M trading volume indicates big money is taking deliveries; the panic sell-off can't push it lower, clearly someone is backing it up. Third, the 4-hour RSI has broken below 25 into oversold territory; the last time such an extreme value appeared, it rallied 35% in three days.
But the bearish reasons are more spine-chilling: First, there has been no bounce at all since the crash from 0.44; it's entirely a one-sided gradual decline, and market sentiment has collapsed. Second, at this level, the main force can easily continue to paint pins; if 0.31 breaks, the next support is at 0.27, with another 10 points of room. Third, a 24h drop of 25% without any bearish announcements is simply capital flight; without substantial positive catalysts, it can't be stopped.
My personal trading discipline: go lightly long at 0.315, stop-loss set 10 points below 0.30, take-profit first at 0.35. But if your position is heavy, I suggest waiting until it firmly reclaims 0.33 before acting; don't catch a falling knife on the left side. With 16M in depth from pending orders, this board isn't something retail can handle.
Remember, this kind of K-line littered with corpses is either a golden pit or a mass grave. I bet on the former, but prepare to run from the latter. If it can rise, hit 1; if it's going to crash, hit 2.
