The answer to the question is that there is no cryptocurrency with a higher market cap than Bitcoin. Bitcoin is currently the largest cryptocurrency by market cap and has held this position for many years. However, there is speculation that this could change in the future as other cryptocurrencies, such as Ethereum, Ripple, and Litecoin, gain more traction and popularity. There is also speculation that Telegram's upcoming token, the Gram, could potentially challenge Bitcoin for the top spot in the future. However, CZ, the CEO of Binance, has stated that he does not believe that any cryptocurrency will ever surpass Bitcoin in terms of market cap.
