Two Days ago I joined a trading website, where you can learn everything about trading and have a free demo account.
I haven´t enough time yet to research everything, but I will do so very soon.
The thing I like: just a few hours later on the next morning, I got a call to the number I signed up with.
An Account Manager helped me to setup my Account and explained some things.
The minimum investment is €250. Gonna do some research tomorrow and update this post.
