if it's indeed all that great like you claim and according to your own words only minor improvements are needed to get into tier2-rank, it doesn't make any sense at all for you to sell. based on that I think the questions and remarks of others in here are no trolling, but rather useful additional informations for anyone considering to buy this site.
edit: typos
Unfortunately with the downward price decline of BTC, we no longer have as big of a team as we once had; thus we have no human (or capital) resources to invest back into PeerBet and Bit777 - this is from a development and marketing perspective. CBTC (the gaming network) is publicly traded, so you can track the facts stated independently.
At the end of the day, Dice Sites are a dime a dozen. Literally - there could be several hundred out there right now, with no clear distinction from one to another ! Anyone can make a dice site and get it out there in less than a week.
What any newcomer can't do is mimic the same
reputation, brand, and player base associated with a site that's been running since 2012. That's the lure of PeerBet and Bit777. Along with those intangibles that can't be built in a week, both sites also accept many different alt-coins, and allows trading (exchanging) of the alt-coins all within chat via a public API. Couple that with Bit777 which has over 40 different casino games and we stand by that this is a great buy for the right, motivated, buyer.
