Most lenders prefer any stable, high-value altcoin because it is so similar to bitcoin and any losses are easily recuperated. However, Vod gives a nice little list of valid collateral.
I suggest you offer some collateral, or just lock this thread quickly before you get neg-bombed. (If you lock this thread you'll probably still get negative trust.)
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 Litecoin (also written as LTC). 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
