Base on my experience, its really hard to spot shitcoins, especially if they are still newly launched. Most of the shitcoins/ scam coins are exposed only after some time and that could even be months until you realized you are holding it.
Well, if we try to determine if the project is a shitcoin or not as soon as it launches, that is certainly not easy to define because the trading volume and demand of people is still not stable, besides, the next plan of the project may not be clear and launch, rushing in judgment just easily leaves mistakes and misses opportunities. At the very least, use a certain amount of time to consider, if it's a shitcoin, the value will drop relatively quickly over time and very little liquidity, conversely, a good altcoin will have good liquidity, the value can always go in a positive direction
You can somehow identify if that particular project is going to be a shitcoin. You can see it when the project is still running and you noticed that their target is not yet reached and they are running the project for a long time, that makes them somehow lose money because if we consider the payment they are giving to the participant during the project or sale that has a big impact too.
Sometimes is hard to spot shitcoins or scam, at least for new coins i don't know how to choose and choose better projects instead of falling ones.
If you don't have any knowledge to know scam projects or you can't make an analyst against them I suggest to just active on scam accusation board.
Before you open this forum you should directly choose scam accusation board as your destination. I believe you will know what scam project on this forum even the project just launch an Announchment on this forum.
Knowledge is really an important attribute you need to obtain before being involved with cryptocurrency because one single mistake can lead to a bad situation such as losing money. So if you really want to invest money, you should study every project by reading the important information. You can actually see it at their whitepaper and to know also the roadmap of that particular project although roadmaps sometimes not being followed.
