Some will say that Bitcoin is the king of cryptocurrency, and all other coins are alternate coins. Other opinion is that because there are also some other good coins out there, they should not be treated as alt coins. Here I talk about Ethereum, Monero and few other good coins. At the and, for me it doesn't matter if something is called altcoin or not. Only thing that is important, is the value of the coin and the earning that we can gain from the coins.
