    What happens to your saved money over time

    Saving money seems safe. But there's a risk no one mentions: inflation erodes the value of what you save, every year, silently. Understand the numbers.

    Saving money is considered responsible behavior. You spend less than you earn, put some aside every month, and feel like you're building something.

    But there's a silent problem in this process that almost no one stops to calculate.

    The risk no one mentions

    When you save R$ 1,000 today, that amount doesn't change. Ten years from now, you'll still have R$ 1,000 in your account.

    The problem is what those R$ 1,000 can buy.

    Inflation is the general increase in prices over time. When prices go up and your money sits idle, it buys less. Not because the number changed, but because the world around it changed.

    In Brazil, this isn't theory. It's what has happened in the last fifteen years.

    The real numbers

    Since 2010, Brazil has accumulated over 120% inflation as measured by the IPCA, the official consumer price index.

    In practice, this means that what cost R$ 100 in 2010 now costs R$ 262. The purchasing power of the Real fell by more than 60% in this period.

    If you saved R$ 10,000 in 2010 and did nothing with that money, today those R$ 10,000 buy the equivalent of R$ 3,800 from 2010. You didn't lose the money. But you lost more than half of what it could buy.

    This is the invisible cost of saving in Reais.


    Does saving resolve it?

    The savings account is the most popular investment in Brazil. But the historical return of savings rarely consistently outperforms inflation. In several periods, those who left money in savings still lost purchasing power, just at a slower rate.

    Other fixed-income investments like Tesouro Selic and CDBs perform better, but they are still exposed to the same structural problem: the return needs to beat inflation for the money to truly grow in real terms.

    What Bitcoin did in the same period

    Bitcoin is an asset with limited supply. Only 21 million units will ever exist worldwide. This programmed scarcity makes it behave differently from traditional currencies, which can be issued without limit.

    In 2015, 1 Bitcoin was worth about R$ 1,000. In April 2026, the same Bitcoin is worth R$ 375,000. An appreciation of 375 times in eleven years.

    This is no guarantee that it will continue this way. Bitcoin investments have high volatility and a real risk of loss. But historical data shows a structurally different behavior than the Real in the same period.


    You don't have to choose between one and the other

    The discussion doesn't have to be "sell everything and buy Bitcoin" or "stick to Reais only."

    There is a third option: accumulate Bitcoin gradually, without making any investment decisions, using the purchases you already make day-to-day.

    That's what SATS does. You enter through the app before buying from partner stores like Carrefour, Shopee, Booking, and Drogasil. The purchase is made normally, with the same payment method you already use. And part of the value comes back to you in satoshis, the smallest fraction of Bitcoin.

    No market timing. No money transfer. No investment decision.


    Frequently asked questions

    Do I need to understand Bitcoin to use SATS? No. You accumulate satoshis automatically. The app shows your balance and you track its growth over time.

    Is it safe? SATS passes on Bitcoin cashback from commissions paid by partner stores. You don't make any direct financial contribution.

    How much can I accumulate? It depends on how much you buy. With R$ 1,000 per month in stores with 1% cashback, you accumulate about 2,600 satoshis per month. In five years, more than 160,000 sats, equivalent to approximately R$ 600 at the current exchange rate.

    Saving money remains important behavior. But understanding what happens to that money over time is what separates those who preserve wealth from those who only accumulate numbers in an account.
