I think the proof is not necessary at this stage because an allegation has been made which has not been refuted by the OP therefore if the OP accepts the claim then he has no reason to upload evidence but if the OP counter-claims then it is essential for bobyhodob to post evidence.
The OP has logged in here after the claims were made but he never posted here, we have to wait for his reply.
We need to listen to what rocketpot has to say but considering this is the same place that has given out so much money so far, I doubt that they would be out there trying to steal 1 bitcoin from some gambler.
I am sure if you could provide with more proof than just saying you were scammed by the casino, you would be taken a lot more seriously. So far you have just said that you deposited 0.001 bitcoin and turned it into 1 bitcoin and couldn't withdraw and your account was deleted, that's all you said and that was given to us by text from you.
I think the best way to go from here would be you providing us with proof that this happened, otherwise I can claim the same thing, who says you are honest or not, so a proof would be a lot better. Secondly after you provide us with proof (considering you can) rocketpot would have to defend their decision as well.
