The fee isn't associated with Inputs.io its a withdrawl fee for CoinLenders... Inputs.io doesn't have anything to do with it...Never mind you're making FREE Interest and I'm sure he is just trying to offset costs so he can keep the interest rate up a bit and it also helps stop people from withdrawing as often so he doesn't have to worry about a whole bunch of small transactions being filled everyday because it would eat into peoples money more so it makes more sense to wait and withdraw bigger amounts when you want to spend the bitcoin...
I wouldn't consider it free interest, this is misleading to newcomers.
There is a risk that CoinLenders could have a bad run and lose peoples investments, then CoinLenders would either have to keep quite and prevent a bank run or deduct losses from all the accounts.
The only way I am wrong is if all the money CoinLenders is paying interest on is 100% fully insured. I am under the impression this is not the case. I am also not spreading FUD, I know TF will cover losses if it ever comes down to that but there are limits, because if TF had enough Bitcoin to cover 100% of lost funds in the worst disaster, he wouldn't need your money to lend out in the first place.
So please stop saying its free! There is risk and thats the cost.
