The thing is that you cant know if someone is going to pay back even if they are legit and they are willing to pay back at first they may encounter some sort of problem and they wont be able to pay back, what are you going to do then, since you didnt want a collateral
That's true everywhere. Not just in the Bitcoin world. I have a number of credit cards in my wallet and every time that I use one, I'm getting a loan without collateral. Sure, I could walk away. But overall, the credit card company charges high enough interest to compensate for those who do walk away. It's the same with Bitcoin. The risk is much higher, but the potential rewards are higher too. It's a balancing act.
Well i guess but still there is no point in not looking for a collateral, it just makes the deal 100% safe
Actually, I think some lenders are doing it because of competitive pressures. Its not just no collateral loans that are offered either. Now I'm seeing 0% interest too.
