All crypto is a scam. Including bitcoin. Anyone can create a crypto. They are backed by nothing just like the U.S. dollar. No different than any pyramid scheme. The trick is to keep the masses entering YOUR pyramid so it continues. So far bitcoin has succeeded in that aspect. But its day will come. And to say bitcoin is not hackable or will remain a fixed amount is naïve. All digital info. is capable of being changed. Ask any CTO. Know what "crypt" means? It means a vault for burying the dead.
