From my point of view, yes we need another Altcoin because many people are involved in cryptocurrency, because, altcoin is just like an alternative way to gain profit in trading. it also makes the world of cryptocurrency to be balanced, if there is no altcoin, maybe crypto will end. And Also, we should be more experimental to find other new things like altcoin, when it comes to investment and in cryptocurrency world.
The Altcoins provide a variety of options for different people to choose from. Their potential for growth may not be as high as those that were mentioned from the first statement, but they offer good alternative for people who could not afford to get themselves Bitcoin and/or other expensive coins that are existing.
