Personally, I don't agree with you. "Old is the Gold" If you say the old coins no more profitable, actually you are wrong. Here is the best two example for that. The Bitcoin and Ethereum. We know about these two. These both are at very lower prices in the beginning. But it's price was increasing rapidly within 2/3 years. So I believe, don't give up. If you have old altcoins with no values, don't worry, maybe it will be having a great value in the future. So be patient.
