Question: Is there a better Cryptocurrency than Bitcoin? or will there be?
Yes, there can be.
It is because Bitcoin’s fundamental protocol cannot be changed but new Cryptocurrencies made by some developers could have significant improvements on the base and provide much better service and features for users.
There has already been thousands of new Cryptocurrencies created following the creation of Bitcoin.
Bitcoin still remains as the most popular Cryptocurrency today(February 2018), as it is the first Cryptocurrency ever created and there had already been many participants before any other Cryptocurrencies are exited.
