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 dont think anybody has that knowledge, they would have to be a time-traveller for that to actually happen.
There is a narrative in the crypto space that certain coin is a bitcoin killer and hence people should buy it. Point is that such things are only gimmick. Bitcoin can be called fiat-killer - but does that even make sense? No, because fiat is working fine anyway. So if someone tells you that this coin is the bitcoin killer, take that with a large amount of salt. You are most likely being duped.
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.
Like I said, smart people invest in bitcoin, not in those coins claimed to be bitcoin killers.
