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.
Risk involved in investing in new coins are just so high, either you invest in a coin before it’s listed or you invest after it’s listed, the both is risky, but I will say investing in coin before it’s listed has the high risk. There is chances of making huge amount of money, but also their is chances of losing a lots, so even if anyone will be investing in a new project, then they should allow it to be listed first, they should allow it to be stabilized before investing. I won’t really recommend anyone to invest before it’s being listed on exchange.
