How much would you make as first amount? I was thinking £50 bit even if this times by even 10 that's only 500.
Would 300 be a more realistic start
I think any amount can be invested for the first time. The invested amount is depended on one's capacity. One should not invest any amount which affect one's daily life. I think everybody should invest their idle money. Another things is that one should invest such amount, which he is able to bear loss. But 50 Euro or $50 is very low amount to invest.
Beside these, before investment everybody should study the market properly. He should know the opportunity and thread for the market properly.
