BTC's main players stepping in means a bigger rebound, If they don't step in, even strong support zones barely see a rebound. Look at the green arrows, both strong support zones at 791 and 784 didn't rebound. If the main players had stepped in, even a regular support zone would have been pumped hard. So, K-line charts are just surface-level; what really matters is whether the main players are spending money to push it up.
