Forex

I recently opened a practice account after I downloaded the app on my phone and played about a bit with it. I did however start with quite a large sum of £50,000 I believe.
I'm not really sure how hard it is to trade on there but I went upto around £78,004 in a couple of days.

Was just wondering whether if I had 50k I would've made the same amount with a live account or if anyone else has any experience?
