if angry it seems not, if disappointed and sad it is certain. no matter the slightest frustration there will always be because of our wrong decisions. the world of crypto & trading in particular cannot be far from the decisions taken. it all depends on each of us. the important thing is not to give up easily, let alone give up.
I agree with this, because our assets including coins are things that are beyond our control, if I sell coins in an urgent situation, of course I have no right to be angry because this is urgent, unless I sell coins to improve my lifestyle, of course I will regret it in the future. the day the coins I sold were priced higher than the previous phase.
