Yeah, I think Altcoin is a must in the cryptomarket. there is a interconnection between BTC and Altcoin in the market. both altcoins and bitcoin grow together helping each other so i think bitcoin needs altcoins. so we need altcoins in the crypto world.
altcoin is an alternative to Bitcoin so it is necessary to advance crypto because not everyone can achieve bitcoin. even though they look competitive, they are truly connected. we can see that there are many crypto fans thanks to the existence of altcoins, so I also strongly agree that altcoin is needed.
In every sector, people are seeking for something new. So it's normal to see altcoins as the alternatives of bitcoin or ethereum. This is not a bad thing, this will help the sector grow up better.
