It's probably already too late but I'd say real estate AGAIN

The last couple years been real hot in my region with a ton of new flippers trying their hand again like we learned no lessons from 2008
A lot of people who copped from 2009-2014 came up I think, it's hard to tell if we are at the tail end of another bubble or still in the middle.
It's a lot of people "selling shovels to gold miners" in my area which is usually a sign we're at the end of a bubble. I went to a real estate class that was being run by a big time developer in my city, guy has xx millions of property level. I peeped that the thing for him was giving hard money loans to ppl who finished the course.

. ain't shyt free in life fam
I went out with my friends and I was telling them I looked into it because 'i saw random ppl flipping houses and if they can do it i can do it!!!!!!!!" ....right at that moment i realized it's probably another bubble
