Nadex demo account 25k to 51k+ in 3 hrs *noob*

Hello, just downloaded nadex mobile app about 8 hrs ago and I’m new to trading. By new I mean NEW, I’m 20 years old and have been watching a few YouTube vids that’s it. I’m wondering if it’s normal to be able to double a nadex account in 3 hours? I have never traded and was just messing around and doing 5 min forex contracts. I know very little terminology and am in awe that I actually made 500 bucks let alone 26k+ in 3 hours by just tinkering around. Any input would be appreciated, I have screenshots but don’t know how to load them on here lmao.

Just how many binaries were you trading at one time?

It’s possible with crazy amount of risk, like just walking into a casino and dropping 10k on black…yeah you have a 48% chance to double…but a 52% chance to lose.
