It would help if you provided profit/loss figures, a balance sheet, traffic states, list of assets etc. Making people come to you for these details will deter people making an offer since its quite cheap to build your own site these days.
Not true. Yes, it's quite cheap to build your own... I'm sure a lot cheaper than taking ownership of an already established casino with custom games

but requesting potential buyers to contact them shouldn't be a deterrence, at least not for serious operators.
I contacted these guys a while ago and they said the site had a profit of 2000
BTC over the year and wanted an offer based on that, which just isn't realistic. When BTC is a fraction of the cost it is now, of course theres going to be more bets. BTC is worth many times what it used to be, the valuation needs to be in USD as the current BTC revenue will not match the previous year. The traffic / financials should be made public instead of making buyers PM, theres no need that the information should be made private. Unfortunately, the casino market has exploded with new comers, including many casino's offering 100's of games, 3D games to boot.
Not to be a douche... But I think the financials need to be made public. I have some doubts about the "big wins", especially about May 8, 2014 when a user won 765.65
BTC. Thats nearly $370,000 at what the prices were at that time. Than, the december wins add up to ~$410,000 worth of BTC, nearly ~$300,000 in June, and well over 100k+ for the remaining months. No offense, but I can't see this casino paying out over $1,000,000 worth of BTC in winnings... I don't see the traffic, and you would need a ridiculous bankroll to keep the site going (in which case why bother selling it? You could easily hire someone to manage the site if your making that good of money).
Again, Im not trying to come off as an asshole, but the numbers dont make a lot of sense.
