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.
Thats the real optimism.
It wont make sense if you dont believe on what your buying, common mistakes why most people lose so much in crypto because of their negligence to do research. People who had more knowledge and patience are the one who could rip the benefits.
