SOL recently remains in a generally weak and volatile pattern, with a lack of volume in the rebound and an inability to effectively hold above the key level of $80, indicating insufficient bullish momentum; the sharp decline mid-week has broken through the previous box bottom, and currently around $80 may have shifted from support to short-term resistance. In the context of increased trading volume but stagnant prices, it is likely to face resistance and fall back when approaching the 85-87 region. Consider deploying in stages within this area. Support below is focused on the 72-74 region.
