Most important to note is the rising support line which if broken will invalidate this swing trade.
We can see a continue in price drop to our first (lower white line) as it has served as support in the past.
Two things are most likey to happen, we find support on the horizontal and bounce up so I would put a first buy order at that level (2K sats ).
The price continues to drop to the rising (18K) and that would be the optimum buy level. After this I expect a price bounce to retest the upper resistance line.
Capital management is required.
