I hope this post becomes a legend.
Already had similar post in the past :p so nope.
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.
There is no other coins similar to Bitcoin even in few years later in the future. There is none close to Bitcoin in terms of usefulness, the decentralization and the community around it, other coins would not have stand a chance against Bitcoin.
Also there is no such thing such as late in cryptocurrency you still have a chance to gain profit because you are still young enough to do long-term holding. Because of Bitcoin's nature, you will find yourself getting a profit in the future if you are patient enough with your investment.
