To be honest, the word scam has been used far too much nowadays, people calling bitcoin a scam, bitcoin lovers calling altcoins a scam, the list goes on and on. As long as you don't put more money then what you are willing to lose you should be alright. 

There is a few people out there which I been following who already broke even and are now in profit so if that is the case you can't really call it a scam.
