It depends on what it means to "beat Bitcoin" ... Of course, there are cryptocurrencies and there are many of them that have a much faster transaction rate than Bitcoin. Still, Bitcoin is the most popular and stable coin in which investors are confident. Even if we compare in the current market situation: the price of bitcoin fell by 70%, while for the rest of altcoins, by 90%. If there is any coin that becomes better and more popular than Bitcoin, then not earlier than in a couple of years.
