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.
Its others peoples choice and they have their own reason. Some people doing trade and cutting their loss and some people prefer hold their coin for long term. But i do believe bitcoin will recover again and reach highest price
In this time trading and holding both is very beneficial, so if those people have high knowledge about trading they are really doing a high profit because nowadays the bitcoin price is goes to up and down very quickly in this way many trader recover their loss, and also if those people hold their bitcoin they are in benefits because there is no doubt that in the world of crypto after a big dump there must be a pump very soon.
