Por que bilionários usam cartão de crédito?

Because psychiatrists have 20 credit cards and they all use them. I think this is a problem with DVDs. Nothing like that, in fact, it's a make-up machine. Wait, what? Yes, even if this is really fun and simple. When you pass a card today, the money goes out of your account today, right? In fact, no. I pay the fee just one month later. Exactly. So, for 30 days, that money you just spent, it's still going to be in your account. So, instead of letting this money be stopped, they put it in a account that rents you, earning money with water that they already spent. Let's say they spend a million on the card this month. If a million is running for 30 days, with 5% of the year, it will give us 4,000 reais, without doing absolutely nothing. It is literally a free money falling every month on your account. Okay, but and the creator of the card, they pay everything to the list. Simple, without paying bills. And here comes the second advantage. Each of the money is at the point, cashback, millions and other rewards. That is, they earn from the two sides.
