I feel like purchasing a token before the listing gives much more space for profit, but he mentioned that there's also a huge risk of not knowing whether it will end up getting listed and that was a fair point.
As for me, I would hardly advise someone to purchase a token before it is listed because of the serious risks it involves. Honestly, if someone is lucky enough to pick the right project to invest in before it is listed, it can result in huge profits. However, the truth is that it is not easy to find such projects.
I have a friend who likes purchasing tokens before they are listed. From the experience I have gained from his side, it can be bad when someone doesn't have enough money to continue buying different ones. For example, someone may purchase ten tokens before they are listed, but it is possible that only one or two will perform well when lucky.So, for me, purchasing tokens after they are listed carries less risk because you can do proper research before investing. Even then, some investments can still yield reasonable profits.
