Why $72K is the invalidation level for my $BTC short.

For the bulls to maintain any chance of another short-term push higher, $69K needs to hold as support and $72K would have to be reclaimed and stabilized above. Without that, upside momentum remains very fragile.

The problem is that $69K is currently acting as a critical pivot. If that level starts to weaken and gives way, the structure likely opens the door for a move back toward mid-range support, where the market would look for its next reaction.

From a structural perspective, losing that zone would increase the probability of another rotation lower and eventually a retest of the range lows.

Just reading what the chart is showing.
