i think alongside the bitcoin obituaries (
https://99bitcoins.com/bitcoinobituaries/) we need a new collection of bullshit coins that claimed to replace bitcoin in the history and their time of death.
so far i think at least a dozen serious coins have made such claims. the oldest one i remember was something called paycoin, then the two newest are Dash and Ether and all of them are either dead or on their way to the grave
This is really the way you say. Many times already different coins and their representatives declared that their coin is the best and it will replace Bitcoin, but so far no coin has succeeded. I believe that 0xBTC will not even be able to compete with Bitcoin, because I have not seen any convincing arguments in favor of this coin.
