I don't know why for me, altcoins that are less considered to have more contributions to the cryptocurrency market I always ignore because I also see that the lifetime of these altcoins is also very less effective for the survival of cryptocurrencies.
I'm not criticizing old coins that already exist in the cryptocurrency space, but in fact these old coins are getting eroded by the times and the marketcap is getting lower, decreasing indiscriminately and dying.
Maybe for old coins, I only believe in Bitcoin, Ethereum and Doge .
