Though the market at this point might be encouraging but that does not mean that altcoin is dead, the price of altcoin is been controlled by bitcoin uptrend, so you don't expect altcoin to increase in their price when bitcoin is still hovering and fluntuating between the price of 40k to 44k in the recent days, people tends to become more interested to invest in other cryptocurrency when bitcoin appreciates in price, if you can remember when bitcoin entered 49k earlier this year some people started making more profits in their existing altcoins and shitcoins, I believe most of them invested more, so op, this how this things works.
