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
In my opinion, it is safe to say that you just invest the money that you can afford to lose. Investing in trading currency entails risks that you might incur losses if you have wrong strategy and decision. So, just invest money like you don't own it and don't have much impact on your money. Just make some research to have a good strategy of something might happen in trading.
