Bitcoin could rebound, but I'm not very optimistic

After almost 2 months of consolidation, Bitcoin dropped hard last week breaking under the channel's trend line support.
In my opinion, this break is very important and signals a top at around 30k and the resumption of the long-term downtrend that started 2 years ago.
Technically speaking, at this moment the price is above horizontal 25000-25500 zone support and a rebound could follow.
This rise should be viewed as an opportunity to sell in anticipation of a break under 25k with a target of around 21k.
Only the price back above 30k would negate this strongly bearish structure
