The most important thing to have a coin's sustainable growth is that investors could see its value that is somehow not seen in many of today's ventures. Developers never have anything to do as a long-term plan, they're always pretending to be optimistic, so they believe it's enough to be included in an exchange that doesn't even have legit volume. That's why most of the new coins dump straight away after the listing.
Any project is risky and the development of those projects will determine the price of that coin when listed. In fact, the bear market is the main reason why those coins are down and investor sentiment is only concerned about profits, so it will be difficult to make a profit. In my opinion, there are not many solutions to avoid this and should limit investment in new projects because the risk will be very high.
Personally, I only buy when that coin is listed at the big exchange and will wait a few days to know exactly what will happen next.
