Before BTC moons, a healthy retracement is valid at this point, could look lower than 16k maybe into the 15-13k area but 16 is a healthy drop.
There is an Order block on the OTE both overlapping to give a good entry, also a build up of stops above the OB creating a liquidity pool which has been touched a couple times which suggests it will reverse after touching this.
The market has seen continuous lower highs , suggesting a bearish trend, this gives me to enter at a good retracement in the market. the Volume of the recent high velocity move also shows instability in the market which is another reason to enter at a retracement.
