Why you shouldn't buy cryptocurrencies from banks like Nubank, Inter, Mercado Pago...
EXAMPLE. The value of the currency on a brokerage will be $50, they will sell it to you for $60.
You will still pay a fee to buy this currency of about 40% on top of its value, and when you want to sell it, you will pay another fee of about 40% again!
DO THE CALCULATIONS FOR YOURSELF AND SEE IF IT IS WORTH IT!
