The application describes a centralized process to maintain the value of stablecoin:
„…each time a dollar of digital fiat Bitcoin Code – Bitcoin Revolution – Bitcoin Era – Immediate Edge – The News Spy – Bitcoin Trader – Bitcoin Evolution – Bitcoin Profit – Bitcoin Billionaire – Bitcoin Circuit is generated, the central entity ensures that the corresponding physical dollar bill is withdrawn from circulation, in order to regulate the value of the digital fiat currency.“
