Well what do you mean by "works" the guys on twitter screaming about "Have fun being poor", were by and large just trying to scam you. Like, I could phone up your grandmother and convince her she's got a virus and she needs to transfer her life savings to me before the hackers get it, that could make me rich, does that "work". I don't know what Crypto actually worked for beyond - creating a target rich environment for scammers, a neat way to buy drugs, and good way for criminals and rogue nations to launder money.
