My question is how long should you have been involved with bitcoin to be desensitized with news that is trying to target investors into making irrational decisions?
There's no how long. It's quite subjective it depends on various factors like mindset, knowledge and some experience among others.
There are People that knew about Bitcoin under a year and they are resistant to market movements
Than some that have spent a decade.
Example of such people are some that held bitcoin even when it was nothing
And still held even after it crossed $10K.
Even after years of being into bitcoin, do you still feel anxious and act impulsively? Or have you gotten a hold of yourself?
Anxious is something I think you would feel if you trading especially futures
There's some annoyance and negativity felt during dips but what matters is how you hold on.
Personally If I feel the performance is getting to me, I just go to the WO thread and read their posts.
It helps.
