Online reports that CNBC's "Mad Money" host Jim Cramer shared his thoughts on Bitcoin and MicroStrategy Shares (MSTR) this week. A caller during the show told Cramer: "I have owned this stock since 2023 and is currently up more than 1,000%. I'm not going to sell it. In fact, after recent adjustments, I plan to buy more." Cramer commented on this: "I have to tell you, this is a Bitcoin game. I prefer actually owning Bitcoin." He also mentioned that Citron has recently carried out some kind of short operation on it, and suggested: "I can only tell you that you own Bitcoin. This is the winner."
