Next bitcoin?

I am a high school student. I learned about Bitcoin, but it’s too late. I was so young. Because I was 4 years old in 2009. But as history tells us, bitcoin killer will emerge one day. I want to find out such coin, but I don’t have enought knowledge and ability to do that.. I want to ask the smart people here. Is there a coin that is similar to Bitcoin now? something that is perfectly decentralized. I want to invest there. If there’s a coin you’re making, is fine too. Just let me know. I hope this post becomes a legend.
