I don't know if we need more cryptocurrencies for specific niches.
For me it is like missed idea, better support one crypto than divide your attention and resources to create altcoin people will barely touch.
everyone just want to scam these days. if you own a coin, its going to be easier for you to scam from newbies hopeful to earn few bucks when they see green lights of these coins. this is exactly the reason newbies should just put their attention to tokens and coins that existed long before they have joined the cryptoworld.
