they are being manipulated and lied to if they creator states when he releases the coin that 1 block will be created every 10 minutes but in reality 1 block is created every 1 second or less. then the creator releases no information on how to mine the coin so after the first couple hours 90% of all coins that will ever be created are already mined and the creator owns nearly all of them. he released the coin with a lie and manipulation and did so in a way that no one else would be able to mine the coin until he already owned nearly all of them. that falls under the definition of a scam in the OP.
