Cramer's lightning round: 'Go buy some Ethereum' instead of Hut 8 Mining

• It's that time again! "Mad Money" host Jim Cramer rings the lightning round bell, which means he's giving his answers to callers' stock questions at rapid speed.

Hut 8 Mining Corp.: "Blockchain company, they're a dime a dozen, unfortunately. I wish it were more special than that. I don't think you have anything proprietary with that company. Go buy some Ethereum."

Dynavax Technologies Corp.: "You know I've liked this company. You know I like companies that are involved in anything that's what I call personalized cancer, personalized immunology. And that's one of them."

Sprinklr: "People didn't like the quarter. ...There are not enough companies that follow this to be able to get a true picture on it. That's part of the problem with having all these companies come public. Very hard to get a real reading on it."

Ping Identity Holding Corp.: "Look, I happen to like Ping very much. I happen to like cyber very much, but my recommendations are you do Palo Alto [Networks] or you do CrowdStrike right now, OK?"

Correction: An earlier version of this story incorrectly stated the method Sprinklr chose for its public listing on the New York Stock Exchange.
