A 'new bitcoin' or a "better than bitcoin" cryptocurrency has been created every month.So far,no coin has proven that it deserves the right to be the new king of crypto.All those articles are a bunch of BS.
It would be great if they really create such energy efficient crypto,but I highly doubt it.

However, it is not about a new Bitcoin killer coin but rather one of the existing altcoins attracting more user attention and acquiring more real adoption in the long haul. For example, Dogecoin was created mostly for kicks and it had twice as much shit kicked out of it while it is still alive and kicking. Indeed, it can't be a Bitcoin killer as that would be beyond such ridiculous even for Dogecoin. Nevertheless, Litecoin could easily become that competitor to Bitcoin, at least as far as real use is considered
