SMAC (Social Media Advertising Coin) uses social media accounts to raise advertising revenue and then buy back coins at the market rate to facilitate growth in value.
The first buyback (about 6 BTC) has already occurred successfully and resulted in a near doubling of the value. With only about 600,000 coins in total this is set to skyrocket as more and more buybacks occur.
Coins which are purchased during buybacks will NOT be resold and instead will be redistributed to those who are holding them.
This combined with the usual advantages of a cryptocurrency allows SMAC to become a unique financial tool and investment opportunity.
The team has put together a simple video that explains the basics:
