I think the reason why many new miners get burnt is because they have no idea what the concept of "difficulty" is. I had this problem when I started mining in 2014. Bitcoin back then was like $1000 and I understood that if it goes to $900, I will make around 10% less money and I was fine with that and kept buying GPUs.
However I didn't realise that there is difficulty and that also kept going up, while price kept going down. I remember having a bunch of expensive R9 280X GPUs and I went from making $10/day/GPU in Dec 2013, to $5/day in Jan 2014, to $2.5/day in Feb, to $1.25March to pretty much breaking even with electricity. And price didn't halve every month. It was the difficulty which kept going up way too fast.
I keep saying that and they think I'm lying to them ehhe, trolls will always be trolls. I guess their calculations are flawed as their brains.
