Is there an off chance that the people who gave you this magic substitute monetary standard device know where you live?

Yeah the same with me.Credits cards want yearly membership, paying just 1 euro to activate whatever amount of money on debit card i want seem better to me than paying a yearly subscription to a credit card.

What happens if I buy the bank with a half-empty limitless credit card?

This.

That's the problem, the bubbles aren't large enough to crash the global economy, just relatively small spikes. The idea that 1 individual will own all assets on Earth and everyone else is effectively rents parts of it would be a great plot for a book. Imagine the the dispute over that person's heritage when he or she dies!

That's why one waits for a credit offer with no annual fee & a low (if one is lucky 0%) introductory rate. Use it to pay off one's outstanding high rate bills, then budget to pay off the transferred balance before the introductory rate ends. But other than that; yes, I agree that one should try whenever possible to live within one's means and spend only whatever cash is on hand.

here few people can obtain a credit card. A student, or a precarious worker cannot obtain a credit card.
So I just use a prepaid card or a debit card.
debit card is free.
prepaid card is also free for under 26 (while you have to pay 10€/year when you are >27).
