old coins will continue to compete with new altcoins and you can see everything on coinmarketcap and in the top 1 - 10 are dominated by old coins. This means that the information provided by CoinMarketCap provides evidence that the old coin can still maintain its demand and volume. although new altcoins are currently gaining popularity.
That is very clear indeed, and what I see at the moment are all the new altcoins trying to make themselves more popular in the crypto space, on average they are always difficult to compete with the older altcoins.
