I think alt coins have a great future ahead for it and some of the altcoins proved that they are giving out new options to people who have different set of ideas, I love all altcoins making our world easier place, but we have a lot of altcoins in the market that you need to know and research it's fundamentals. we all know that some altcoins are shit and some are dead so be very cautious on investing and trading those coins.
Actually the cryptocurrency world has too many altcoins, same idea and clone more coins every day. It makes the ecosystem of the cryptocurrency world become bad more and in someday, we will have a cryptocurrency world with many shitcoin everywhere.
I would also add that some new altcoins with the same concept and idea, but with better development and technology by entering market, just move away coins that were gaining potential, it is just a "war" in crypto world where only the strongest coins will survive.
