Reserva is a virtual currency designed to increase in value over time. It is not a cryptocurrency.
Cryptocurrencies are decentralized. Reserva has a central authority, the Reserva Central Bank.
Here's how the money back guarantee works:
Because they're more expensive. The Central Bank sells secured Reservas at a higher price than the current open market price. Day-traders and people paying for daily purchases will prefer unsecured Reserva.
Distributed systems are less efficient than centralized ones. Bitcoin's electricity usage is well known. Centralization allows us to offer extremely low transaction costs for businesses.
Reserva will not charge any fees for a transaction performed in Reserva. It will charge a maximum fee of 1% (and hopefully much less!) for any transaction performed in Dollars or Euros.
Most central banks adjust their money supply to target an inflation rate of 2-3% a year. In contrast, Reserva's central bank adjusts the money supply to achieve appreciation.
The people who came together to create Reserva are all paid in Reserva, so you can trust that it is in our best interest to raise the value of the currency over time.
