It's not right all of are old coins no more profitable. Some of old coins are more profitable. I know every old coins are not more profitable. Some coins are good profitable.
It is strange to compare the oldest altcoins and the new tokens. I suppose both of these categories can give you the profit if you choose the best cryptocurrencies. I am sure that DASH and Monero will stay the best ones.
Technically, it is not good to compare old coins and new coins or tokens but to the strange change which occurred in thr crypto currency acouple of weeks back. It shows that some new coins or tokens does have the right utility to make through the crypto market because they make good pump despite the strong market correction.
