It all depends on the mindset of the newbie, if he is here for a serious purpose, I don’t think he would even think of giving up because giving up is failing and if he is determined to remain in the forum, he must fight to stay here.
Those who give up in this forum shouldn’t have even started at all, and remaining relevant here comes with lots of dedication and sacrifices that you need to put in other to get to the heights that you wished to get.
The major thing to do when a newbie is faced with challenges is to keep trying, keep pushing because every senior member in this forum faced similar challenges, but they kept their hope alive, and are still moving.
I wouldn't completely agree with you.
People join this forum because they have certain expectations. If those expectations are not met, why would they stay on the forum? There are many different ways to get information on crypto these days, from Telegram groups, social networks to AI.
If someone finds this forum to be a place where they no longer feel welcome, then it is quite natural and normal for them to move on.
