Seriously? I suspect he lost a significant for him amount on slots, and now blaming the site because, and this is his only proof, "you can tell when something is off". Also, I suspect he doesn't know that Duelbits is only providing its platform to various slots, never interfering with games. Further reading of his posts with such parts as "1 Btc for any information that will identify ..." has only reinforced my first impression. It would be laughable, if it was not so sad. This guy needs professional help as soon as possible.
When we deposit too big money in a gambling site, that will be our first mistake because gambling is not a place to make money.
So whatever will happen later, we should realize that is the consequence of what we decide before.
Hopefully, everything will be okay for him and it is a lesson for him not doing the same mistake in the future.
