You can't compare BTC to most altcoins. Most altcoins which are ERC 20 are just created for trading and profit purpose, no usecase.
Since it's your friend that brought you in, I think you ask him. You can't get anything.
of course bitcoin is the king of all cryptocurrency that exists even ERC20 is created from bitcoin technology developed and created erc20 many platforms that develop blockchain technology owned by bitcoin so at least bitcoin is better than other altcoins.
