This is sad, considering that the aforementioned coins have a proven track record of stability and reliability. New coins are usually less secure than old ones. Despite the low interest/demand for old coins, they're still actively traded on the market.
Whether old or new, once a token outlives its usefulness it will get dumped. It really doesn't matter when it was created. The tokens you mentioned may not be relevant in the scheme of things in today's world anymore. Investment isn't done based on sentiments and emotions but on fact and feasibility. No one can force any to put their money where their heart isn't. Old projects need to keep up with programmes just the same way they marshal out new ones to keep investors thrilled.
Buying the old coin is not worth anymore except the popular old coins like doge, litecoin or something
The mention of dogecoin for a thriving old project goes a long way to show that we shouldn't give up on old projects that have utility, no matter what.
