I dont think computers have the true ability to create random numbers. Reminds me of years ago, I entered a grand draw and only bought 1 ticket but it was the very last ticket sold and yep I won the grand prize even though most other people were buying dozens of tickets; but I didnt complain ! :p That was a 086 though, no doubt things are more complicated now but I think its a fundamental thing computers lack
Could also be that user was buying a heck of alot of tickets.
Both true lots of tickets and nothing computerized is truly random. However after reviewing the code he won fair and square.
He must be very lucky or be lucky to win prize 3 times in 3 weeks.
As i know, 1 CP worth at least 80k satosi. It's hard to achieve it if only make small trading
