This section will grow over time as new questions come up.
Why do you promote Etoro?
It's the best social trading site I've found so far.
Is it free to use copytrading?
Yes. There are other fees associated with trading on all exchanges (so far...) but it's free to actually copy another investor's trades. You don't have to pay the person you're copying any sort of 'cut' or'commission' - they're trading with their own money, your account is simply copying all of their trades. The person you're copying is getting incentives from Etoro. The more people they have copying them, the more incentives Etoro gives them, so they are gaining from the situation, just not directly from you.
What are the fees?
That's a big question, so I made a video (actually a playlist) which explains most of it better than I can here.
