I think the same.
Altcoin to me is just a way to multiply my bitcoins, sometimes all my bitcoins are invested in a few altcoins but in the end i sell all of them for more bitcoins.
I agree to this as no Altcoins can be compared to bitcoins. None of the Altcoin is near in terms of volume or price to bitcoins. People buy altcoin just to get the profit and then sell them again for bitcoins.
I agree with you because Bitcoin is too hot and when it comes to the crypto market people just mention Bitcoin. Newspapers and media also report on it as the most. So Bitcoin has no competitors and even at the top of the market it ranks first.
