The largest cryptocurrencies are all up for the day, with bitcoin (BTC-USD) as the biggest gainer. The leading cryptocurrency has gained nearly 70% since bottoming out at less than $6,000 last Tuesday.

One possible catalyst is key cryptocurrency market South Korea backing off from its previous stance that the cryptocurrency markets needed to be strictly regulated or even shut down entirely in the country. Now, reports are suggesting that South Korea may be entertaining the possibility of a cryptocurrency exchange licensing system, similar to the one currently in New York.

The recent gains have prompted many bitcoin enthusiasts to renew their calls for $25,000 or even $50,000 bitcoin values by the end of 2018. However, there are many high-profile investors who think bitcoin is nothing but a good way to lose money, with Berkshire Hathaway's Charlie Munger being the latest to voice his negative opinion.

Berkshire's Charlie Munger has even more harsh words about bitcoin

Munger, the 94-year-old vice chairman of Berkshire Hathaway, is the latest billionaire to publicly criticize bitcoin (BTC-USD) and other cryptocurrencies, following JPMorgan Chase CEO Jamie Dimon, activist investor Carl Icahn, and Berkshire's chairman and CEO Warren Buffett.

Speaking at the annual meeting of the Daily Journal, Munger referred to bitcoin as "noxious poison."

He said that he considers the surge in bitcoin's popularity to be "totally asinine" and said that the government should have cracked down on it when it began to spike in the last few months of 2017. "Our government's more lax approach to it is wrong," Munger said. "The right answer to something like that is to step on it hard. I expect the world to do silly things from time to time, because everybody wants easy money."

These latest comments come after Munger's previous warning on bitcoin. In November, Munger called bitcoin "total insanity," and said that people should avoid bitcoin "like the plague." Buffett, Munger's longtime business partner, has said that he's almost certain "[cryptocurrencies] will come to a bad ending."
