of course there is risk when you try to profit from something. the reason of lending is mainly to gain interest and in the case of not returning the btc, you gain control of the acc. however, it is still very troublesome for me to try to go and sell acc.
yeah risk is a part of that but we can get good amount of bitcoins every month. Better get contract with dollar contract for interest because One of my friend lending bitcoin to the people. He is having bonding system for that and He is earning every month Some good amount of money by Bitcoin lending.
