Bitcoin holds 57% of total crypto value, Ethereum another 11%, some 15% is in centralized instruments like USDC or XRP, which are not really cryptocurrencies.
In addition to that, there are also 10.5 million altcoins (10000 new are created every day). But all of them together hold just 17% of crypto value. So you can, of course, create another millions of forks, but it won't make a dent in Bitcoin value.
