Can you include your proof or analytical technique that states as you describe? We need proof, we need to know. Indeed there are coins that are the scam but not all altcoins are the scam. Many coins can survive in crypto even though they get rivals from new coins. That's because many communities are investing their money into the coins, so the coins can survive and thrive. If it is a scam coin, I think he will immediately leave the crypto after they get the supply from the investors.
