$BTC is trapped between a massive whale bid wall and an even bigger sell wall.

$77.6K has $4.6M+ sitting on the bid, with multiple $1M–$2M orders stacked underneath.

But $81K is the real battlefield, with $7.5M and $12.4M sell walls sitting at the same level.

If $77K holds strong, I’m expecting another attack toward $81K–$82K. Bulls still have a chance, but they need to break that heavy supply first.

For now, I’m watching both levels closely. One break could decide the next move.
