It's hard to find out unless you'll have a leak that a coin is going to be pump or a huge influencer is shilling it, but why look for a coin that looks like a pump and dump, it's too risky investing here, why not go for coins that slowly developing itself and wait for the right time to pump, you can check the coin's channel for the latest news and you decide if it's going to explode.
Sometimes coin channels are also not fully referenced because they are also part of the influencers who get paid for what they promote, for accurate information we can join VIP groups or analyze any project development that has been recommended.
I don't really like groups discussing VIP signals. At first, they gave good signals, but over time they used followers to create hype in the market. this is almost the same as what influencers do with their social media followers.
finding a new project that's about to explode, to be honest it's really hard. but for altcoins that are already on the market, of course finding one that will explode requires analyzing major updates of the project in the future.
