I will never sell under 20k$, even if Bitcoin go to 100$ ...
The peoples who bought Bitcoin at 19k$, why you are selling them now ? You bought at 19k$ sell higher than that !
If you don't beleive at this technology do not buy anymore.
that's fair.. but:
1) what if price never touch 20k again?
2) you are losing the opportunity to gain something via trading (i admit not everyone like to trade)
my little and obvious suggestion is to not move 100% in single moves, unless you have a very small bag
