It depends. Because if the new existing Altcoins will be more promising and will give more potential to earn more profit compared to the old Altcoins, then there could be a possibility that new Altcoins can be above the old ones. It will surely affect the pricing of the old ones once people specially talking about investors have notice that it would be better to invest into the new existing Altcoins. There are already lots of existing Altcoins in the market which only exhibits that there is a wide competition between those different Altcoins. As of now based on my observation, still the old ones are the most recommend and preferred Altcoin by many compared to the new ones. I am believing that there is a bright future for the Altcoins just like what the Bitcoin have attain. There is always a room for improvement in Altcoins so we can expect a lot more to come which can have a more potential than the old ones. But whatever happens, the important thing is that we will all benefit on it.
