That was honestly a brilliant post, the sad thing i have noticed, is that even if you tell new crypto traders these things, they often don't "get it" until they have been burnt, its like a child being told not to touch fire, they dont learn the lesson until they touch the fire.
And, i throw myself into that camp as well, i was exactly the same, however, content like this is really good to have out there, because as you say, when you have those negative experiences you reflect on them as a trader and become better, and things like this are excellent resources to point people into a better direction.
