The gap has been filled, but that doesn't necessarily mean it's the ceiling.

Today before sunset, I watched BTC rise again, with the weekly resistance at 80,600 giving a pullback yesterday, and today it directly filled the 81,000 gap.
The daily chart also closed above 79,400, indicating that it shouldn't be simply viewed as a false breakout.

To be honest, my idea about the 81,000 level is that the main force might push a few hundred more higher,
and at the same time, absorb the liquidity above.
But all of this depends on the choices of the main force.
Anyway, I have already set up a short position around 80,800, with a stop-loss just above 82,000.
Personally, I only see up to around 81,000; since we've already reached that point, it's time to short.

As for those voices saying 82,000, 84,000, 90,000, I honestly can't see that far.
My recent half-month perspective is this wide—81,000 is a gap, and it has now been filled.
If it can go higher later, that would mean I was wrong, but since it has reached my expected target, I will short.

To determine whether 81,000 is truly the top, the key is whether it can fall back below 79,400 again and not recover.
If it ends up like that, then filling the 81,000 gap really marks the top.
