I heard lending out bitcoin will make our bitcoin to grow in pace as well as securely. But, we need to verify the borrower more thoroughly before deciding a borrower. Getting a salary in bitcoin would be a more secure option :-)
lending out bitcoins to people isn't as interesting as it looks. especially when altcoins are being used to secure the loan. what if the altcoin price of the coin that is being used as collateral is dropping with 50% and the one that took the loan defaults. that means the potential profit is gone and you lose a part of your bitcoins too.
But most of time peoples not taking any shady coin as escrow which can give them big lost because they now its could be worst for them just few good and reputable coins are accepting as escrow is not bad idea and this is going on for some time without any problem
