A while back some guys made a cryptocurrency called Dash, perhaps you've heard of it. It currently has the 8th largest market capitalization at almost 1.5 billion dollars. Those same creators also got together and made PivX which was basically Dash with better features and more advanced technology. PivX is an upgraded fork of dash. This being said PivX is worth only a fraction of Dash and currently is the 47th largest crypto at just over 100 million market cap, or about 1 /15th the size of Dash. The reality is that the PEOPLE determine the value of cryptocurrencies NOT the technology.
Now lately a lot of people have been hyping up EOS like crazy, saying that it's going to be the Ethereum killer and its the best technology. EOS is actually made by the same guy that made Steemit. At the end of the day EOS will in all likely be successful when its finally done with its year long ICO (which I find to be absurd TBH). The truth is though, that EOS WILL NEVER be as valuable as Ethereum, and to think that this could happen is insane. Ethereum has built an unbelievable community of powerful businesses and users, and that doesn't just take 1 day. Again it is the backing that determines the value not the technology. When EOS is finally released it will have a ton of distance to cover to catch up to Ethereum. Ethereum is the king of decentralized applications, and I expect it to stay that way forever as long as the government doesn't get involved or a major bug/exploit is not found. Don't believe the hype, EOS is not Ethereum.
