it seems like alt coins will fail, as the adaption of bitcoin, its the only getting accepted by merchants, the others will fade. no one will care for the alt coins, the others were just a ponzi. why do we need the other coins when we have more then 10 digits in bitcoin
We need innovation to move forward in the cryptoverse. Bitcoin has stagnated with it's innovation because the developers are scared to do big changes with the blockchain/blocktime. The new alt coins shows different ways to do stuff with the blockchain. Take for example Blackcoin with its PoS 2.0 solution. It has a faster transaction time than Bitcoin which is better when you actually want to buy something with your coins. It also have better security when it comes to 51% attacks and not to mention the energy saving since it's Proof of Stake. And then we have Ethereum with it's contract scripting system.
This is just an example of innovations and solutions that the other altcoins can come up. Bitcoin will need to change if it wants to be #1 cryptocoin in the future.
Dont take me wrong here, I love Bitcoin and the Blockchain Technology but we also need the altcoin development to try out all the new innovations.
