It's not madness. This is called the 4th and 5th industrial revolution 😉 they are already studied in academia

You can call it madness, but I see a revolution.
The PIX has reduced physical money, online shopping has affected traditional stores, digital banks have changed the banking system, and streaming has diminished traditional TV and put an end to DVDs.
Today it is already possible to shop with cryptocurrencies, and with the real losing purchasing power, I believe they will gain more and more space in daily life.
Now that I have turned 18, I will gradually start to build a crypto wallet, thinking long-term and depending less and less on traditional currency. The day the real falls... I will profit from the decline of my currency 🚀💰
