Anyone that has been in the crypto space for a while as an investor or a trader would understand the importance of timing when it comes to making profits or losing money.
While there's no 100% way of knowing exactly which project would do well and how well it would do, it helps that we're having features that gives us a higher chance of making the right decision.

All of these help to increase the probability of finding gems very early, and I believe it would only get better from here.
I've been in the crypto space for quite some time, and until now, I can't find new projects that has a potential in the future with 100% accuracy, and I don't think that anybody can TBH. If they are, they must've known an insider or at least there's something wrong with it.
You've said already that there's no 100% way of knowing which new projects has potential or not. Being in the space longer can make better decisions than that of a newbie, but still, they can lose their money. Yes, we have features, and websites that would help us, but in investing into new projects, there's no 100% certainty. If you're investing into them, better be ready just in case the worst thing happens which happens for most of the time.
