Bitcoin and Litecoin are good very promising coin.
But I don't know why they have very little demand while most Altcoins are being pumped to the moon.

What do you mean? Where did you get that idea? BTC is the one that has the most demand in the market always although I do not think I can say the same of LTC.
I don't know about anyone else, personally I saw a lot of value in the litecoin, I had seen enough of Altcoin being pump to the moon simply due to the marketing hype, that they don't even provide an usable wallet, and not to mention they didn't even start to develop something useful, lite coin is a well established coin with strong dev support, this is something making it valuable, but they don't have good marketing team to creating a lot of hype.

Note: a promising coin do not necessarily it will be pumped to the moon, I had seen plenty of promising investment being screwed, I would prefer not to put money into promising coin, but put money into the coin that making the most hype.
