I'd use stuff related to steemit. Let's see what I got.
So people hear crypto steem and then steem dollars and they be like, mama-mia I'm going to make money. They come on board, write their introductory post and go like OMG I'm going to make so much money here, hahahahahah(because they made some few bucks). After the first three posts they go like, you know what? I quit, I give up, I'm over with Steemit, cryptocurrencies aint ma thing. (Why? because they got 0.00).

It's not funny right? :(
