In December 2024, he sat down with entrepreneur and business executive Michael Saylor to discuss bitcoin strategies. Using a sports metaphor, Saylor explained that there are certain games that people would only watch and not play. If the team wins, it would mean that the tickets would get expensive in the next season. Saylor further explained:“There are other games you can play you go into a casino and you play the game but you know the game's rigged against you. There are some games where the house wins you're not winning.”Saylor then mentioned someone named Satoshi who created a game that everybody could win. He explained that Bitcoin was such a game. He also told Dave Portnoy:“Satoshi gave us a game we can all win right and big Bitcoin is that game it's you know that there are certain things where like you don't want to be on a network where they can censor what you say and they can freeze your account.”Saylor said that Bitcoin was a kind of money system that didn’t block where you sent your money and didn’t freeze your account. He said it was designed so that, in the long run, people using it usually came out ahead.Dave Portnoy said he is interested in making moneyDave Portnoy noted that he found the concept of Bitcoin interesting. He said:“I've always said I've heard Bitcoin fans also say they buy it because they think it's good for Humanity, it's not even about making money necessarily it's about good for society. I've been very clear I'm on the make money side of things.”Saylor explained that he chose to invest in Bitcoin because he felt that money was an important part of life, whether people liked it or not. He said that if someone kept their money in a place where the government made the money lose value or the bank froze their account, they would lose.He said people didn’t want to trust their money to unsafe banks or weak currencies, and that Bitcoin was appealing because it let people stay in control of their own money.
