Litecoin, Cardano, Ethereum, and all coins except Bitcoin are Altcoins. So, you don't need to mention it.
But I also agree that Bitcoin becomes the most favorite, and I am sure enough that most people make BTC as the most favoriite cryptocurrency. We cannot deny it, not only because this is the first crypto but also how Bitcoin going on so far, its value, market cap, and also our trust on it. Moreover if this is for long term, indeed no doubt.

But if it is for day trade, sometimes it is different. I will prefer to altcoins that have low price, this is suitable for me because the capital is very small, so tthis is for short term trades. However every decision always bring its own risks. And we mat be able to handle the risks.
