You're saying it is a scam because you bought at a high price and then it dropped? You realize how foolish that sounds?
The same thing can happen to you with Bitcoin. You buy at $1000 and it falls to $900. Does that make Bitcoin "a scam"?
As for the rest of your claims ("coinbase will not add", "hardfork is not coming" - both are false and unsubstantiated).
The truth is that developers are playing their tricky games.
They feed us with this
fake news trying to create the volume to dump their premine! That is why it is a SCAM.
