http://bitcoin.casino/ - would consider selling bitcoin.casino around 150 BTC or close to this amount. Do you have the budget for it?
He is looking for a gambling site not a gambling
review site as what you are offering. And isn't 150 BTC too much for your website, which I just knew the name of. Your site is too simple and lacks design for it to appeal to the masses, the 150 BTC you are asking won't return to the buyer even in 2 years. Assuming that you are really the owner of the website I would suggest for you not to take advantage of a guy who is just asking for a person who is willing to sell there gambling site.
the op was a bit vague, just said a gambling site. bitcoin.casino is a gambling review site as you said, but it could also be a real btc gambling site for the right buyer. as for the price, i think its worth it to the right buyer that wants to build a serious brand in the bitcoin casino space. selling for cheap wouldn't make any sense for me
