RE:HH is BS....Let them have their dreams........your nagging is likely falling on deaf ears. The best way to learn the dangers of investing at the top is to actually invest at the top and then to learn the lessons it teaches. Don't try to take away everyone's learning lesson, I bet many need it.
Hell, I learned that lesson myself when investing in a few of the silver miners near the top in 2011. Won't make that mistake again! Probably a lot of newbie investors here for this go around, let 'em learn - ain't no teacher better than experience!!
