Well, there is a lot of things that are free, but the experience is different if you pay.
Spotify in my country is an example. You can listen to music, but not all of it in a way that you like.
Well, eTORO is a very respectable and established trading platform... so that is a plus for investors. Then again is all about quality of the traders...
The spotify example is not a good one, because i use it everyday since it came out (FREE version) and i'm perfectly more than satisfied with all that it gives to me.
eToro COPY TRADING HAS fees or at least a
HEAVY SPREAD over the market price that can go up to 5%!!!
