The question, of course, is very interesting, given that altcoins are almost the entire crypto market, with the exception of bitcoin. It is altcoins that provide a variety of useful functions of cryptocurrency, while bitcoin purely performs the functions of money, but performs it with great difficulty, given that it is used extremely rarely as a means of payment. Bitcoin retains its leadership in the crypto currency, in fact, only because people believe that it will continue to grow in price for a long time, and therefore has a consistently high demand. But the future is still with altcoins.
