The price of Bitcoin is flying at about $73,000, and expert Mike Novogratz thinks it won't drop lower than $50,000 unless something serious occurs. Novogratz, the CEO of Galaxy Digital, revealed that the recent surge in Bitcoin is mainly because more money is going into newly approved Bitcoin funds in the U.S. As long as the money flowing in stays positive, Bitcoin's price will only go higher, Novogratz shared in an interview with CNBC on Wednesday.

"If the inflow turns negative, that's when the first real dip will happen," Novogratz explained. "Things are looking a bit overheated right now, the funding rates are high, so during these times, you should always be prepared for a dip. I don't see us going below $50,000-$55,000. Unless something big occurs," he added.

Novogratz also highlighted a recent shift in mindset following the approval of Bitcoin funds, noting that more older investors, known as Baby Boomers, are starting to invest in Bitcoin through professional advisors. He pointed out that people holding Bitcoin are hesitant to sell, often valuing their wealth based on the number of Bitcoins they have rather than the dollars they own.

According to Novogratz, Bitcoin is currently exploring new price territories and could even hit $100,000. He doesn't believe that Bitcoin ETFs will end up holding all Bitcoins, estimating that they might cap at around 20% of the total Bitcoin.

The investor also touched on the rise in Ethereum's price, which is now around $4,000. This surge is largely due to expectations that Ethereum ETFs will soon get the green light in the U.S. Novogratz is confident that the Securities and Exchange Commission will approve these funds, especially since there are already futures-based Ethereum ETFs available.
