Ask HN: Digital paper money?

I'm not an expert and I'm really willing to learn from others in case you know more.

Could you please elaborate more in the matter?

As far as I know, they give credits to people and they invest money to earn more money. That's how banks make money and become profitable. And for what I know they can even operate with more money than they really have.

By the way government just guarantees a certain amount of money, in countries like Spain it's just 100K$/account. In other countries like Portugal I believe it's 30K$/account.

EDIT: Responding to the government protection fact.

It sounds like you don't understand how banks operate. They only need to have reserves to back up customer deposits of a percentage, like 10% of total deposits, which means they very much do loan your money to other people and invest it too. And your deposits are protected by the government in case the bank fails only up to a maximum per account, which can be $100k

Thank you for your comment, very much appreciate it as I didn't know any of the Islamic banking finance system. But that's now what I'm worried about.

I don't want a loan. I want my digital money to have the same qualities that physical money has. I'm looking for a place I feel comfortable giving them my money without having to worry about if they loose my money or not while investing it nor deleting me from their db. I don't want them to track my info neither. Just a place where I bring them my money, they save it and they give me access to that money with a debit card.I would pay 10$ a month to have digital money, or something similar to what I describe.

You are right, thank you for the correction. Post edited. The problem with prepaid cards is that I don't feel like my money is secure neither. What if visa fails? What happens to my prepaid card if visa/master card fails?

Don't you feel like it has to exist at least one company in the globe that the only thing it does is taking your money, secure it and give you a credit card?

What if any of these companies delete you from their db? It sounds like I'm paranoid but I don't understand why we do trust them at all. In Spain and Italy two big banks have failed this week.
