this thread to know what kind of collateral is required here
What is considered collateral?
Collateral is something that can easily be resold to cover the loan value plus interest should the loaner default on the loan.
- The best collateral is another crypto-currency, such as Ethereum (also written as ETH). Coins must be moderately traded on multiple exchanges.
- Some digital wares such as domain names can be considered as long as the user cannot recover it.
- Small valuable items that can be shipped though the mail - i.e. gold, silver, iphones, etc.
- Large items, such as a motorcycle or guitar can be used if you live close to the person giving you the loan. Try localbitcoins.com
What is not considered collateral?
- Items they want to sell. They don't want it back, so they will default. It's scammy unethical behavior and will lead to negative trust. Check their recent posts!
