The host of CNBC’s Mad Money show, Jim Cramer, has issued more warnings about cryptocurrency. Cramer is a former hedge fund manager who co-founded Thestreet.com, a financial news and literacy website. He said on CNBC Friday:

I would not touch crypto in a million years because I wouldn’t trust the deposit bank.

He was then asked whether he is making a distinction between centralized and decentralized platforms. “They fought regulation. They didn’t want regulation and you don’t have regulation,” Cramer replied, indicating that he does not trust any platforms that do not want regulation.

Cramer also commented on the chairman of the U.S. Securities and Exchange Commission (SEC), Gary Gensler, stating that existing securities laws are adequate for the regulation of the crypto industry. He wants the SEC to “come on and enforce” crypto firms.

The Mad Money host added: I think they need to do a big sweep. They have to stop people creating money.
