I have set sell orders at some points, just a small amount of bitcoin in case there will be another pullback below $18k but the fact that bitcoin is getting on over $19k repeatedly in a short period after many attempts to halt bitcoin to break $20k with huge dumps, in the end, bitcoin will make it to surpass $20k in the next few days, so I prefer to sell at $21k-24k.
The price struggles to reach at #20k right now and if you're doing short trades I don't recommend it for those who doesn't able to have focused observation on the recent market changes. It needs more effort to do it in order to watch out real time on the market behavior. The risk of setting up an order is really stressful, hopefully you won't lose big amount on that mate.
