LeGaulois, this is one of the things that the bitcoin world needs--a good and safe way to borrow bitcoin. From everything I've seen of the lending section on the forum, it's a nightmare to do so. I would imagine that any crypto bank would have to collect collateral for any loan being issued, which is what traditional banks do anyway unless a person's credit is solid.
The problem with loans on bitcointalk is that they're often being requested by people who have no or inadequate collateral, and a lot of them have no intention whatsoever to pay back the loan. In addition, there's the anonymity factor. A crypto bank would likely have to verify the identity of the borrower. It could work, but there would have to be major security features implemented on the part of the lender. Loans would look much different than they do currently, i.e., less anarchy, less trust, more collateral and identification verification.
Didn't Trendon Shavers try this? Not sure if he was loaning out money, but he did try to start some sort of crypto savings and loan thing. Look what happened there.
This can be sought with the gold loans from my understanding, in traditional banking we get used to gold loans where gold is given as the collateral. Here the value of the collateral gold is valued 75% and the sum of amount equal to the gold is got by the borrower. Further for this interest is being levied which need to be paid along with the borrowed amount to get back the gold. This way can cryptocurrency bank function same as the traditional banks.
As stated collateral through our forum is purely on trust and lot many have got cheated, this can't be made perfect as it is impossible to collect collateral as well as do KYC. A physical banking system is the possible way to provide loans with proper collateral. These days there were apps that are issuing loans in fiat, and here we're supposed to accept legal norms and if we didn't pay our loan within the quoted tenure with the interest they have the rights to take legal action against us. If we pay the loan properly then we can request for an increased amount. This is a limited amount service where initially what we can get as loan is just $100.
