It's one of the easiest and fastest ways to blow your money if you're just starting out.
With a lot of practice and effort, you can make a lot of money from it but don't put in real money into it atleast within the first 6 months of your learning time. Open a demo account, read and practice trading systems and make sure you show consistent increase in your capital (demo money) for atleast a few months and then you can put your money.
And yea, Etoro is not a scam. If you want more info on reference materials to get started, or any help, just shoot me a PM.
