 NFT's are becoming more and more mainstream, it's easy see that more projects are starting up. With that, the potential for bad actors. 
 Keeping up with all these new projects across chains is a daunting task on your own; it takes time, liquidity and know-how to be consistantly successful.  
 $BCC takes the complexities and time away from the average user traveling throughout the NFT space. 
 Our team and advisors all have acess to groundbreaking NFT startup projects and can properly determine value on existing projects. 
 We will use our expertise along with advisement from our advisors to buy and sell NFT's for profit, which then that profit will be used to buyback $BCC.
