Hodling also has its downsides. I invested heavily in so many projects back in 2017/2018. I was hoping one of them will be the next bitcoin.
Hodling shouldn't be the thing to blame here but your mindset and thinking. There is no project from 2017/2018 that can be considered as the next bitcoin. It looks like you just got dragged by overhype.
I hope it served a lesson for you and I think you are doing great now.

Anyways, I think it's better to move the thread here:
Trading DiscussionYes the mindset and psychology general matters a lot.
I did learn a lot. i don't regret anything.
