No joke, Thomas.
Petr regularly produces videos available to everyone on Youtube. Thus far, his several dozen videos clearly show the development of his platforms and the progress being made.
When you visit his site you'll see that playing RNG only, his starting capital was $400.
He has since:
* withdrawn $4550 (you can work out the ROI pecentages)
* established three accounts: First account 1500$ + Second account 360$ + Third account 1400$
* achieved a total progress of $7810
I think he only plays for about an hour once a week (Petr will correct me if I'm wrong), and his basebet of just 20c on each of 4 numbers increases in a controlled, conservative progression explained on his site and in his videos.So overall, in my opinion the profits thus far are a pretty good achievement given that RNG is a notoriously slippery animal to play with.
