Bitcoin is a currency that scammers used to scam people but not the bitcoin itself. Maybe you are pointing on the bitconnect coin that is a legit scam. LOL! Bitcoin has many uses instead on scamming. There are more good things that bitcoin can do and more convenient than the fiat. Maybe its anonymity made it looks like a scam so I can really say that it depends on how people use it. Just be aware on the things that could scam you since bitcoin transactions are not reversible. Bitcoin is a great invention but we can't really avoid some features that could possibly use on crime.
