I am not that expert in trading but i would like to suggest for you, better start with an amount you can afford to lose, just like gambling while you are practicing you can start by trial and error, because mostly you wont learn unless you try it for yourself, so better try for smaller amount because when you failed then its not that hard for you to start again.
0.1 I think it is enough to start a trade. How do you think, is it too big or very small for beginners?
