The "acrophobia" of the big pancake has acted up again. Last night, BTC briefly dropped below $90,000. Although it has swayed back now, it feels like this 90,000 threshold is as slippery as if it were coated in lubricant; once you stand on it, it slips away. To put it plainly, it is still related to the movements over in Greenland, plus the financial unrest in Japan, causing everyone’s safe-haven assets to flock to the golden leg. Gold has surged to $4,800, and today, this "digital gold" big pancake seems like a mischievous younger brother, still not keeping up with the elder's pace.
