In my opinion, I don't think there is really any special difference between investing in old and new tokens because there is a chance that if you invest in new coins, they could still become shitcoins in no time or generate a huge profit if, luckily, they get pumped. The same can also happen if you invest in old coins. I think it's better to do proper research on any project you want to invest in. Whether an old or new coin, make sure to study the project, and if you think it's really worth investing in, you can invest in the coin.
