hello, I have a project thats completely done and simple to manage and its for sale. https://adb.tc/ could be yours for 1.5 BTC. Lets discuss about the price. if you have questions you can anytime contact me here or at the contact form from adb.tc . also I will soon start a new project where you can also invest. Also I have a 2 Gambling Sites that are currently offline, however, you could buy both for 0.5 BTC and make them online again.

Let me your thoughts know. you would have enough money to start big advertising campaigns/promotion money after buying one of the sites. I really recommend to invest 75% of your 20 BTC in Advertising if you want get the sites popular!
