The risk is very nominal in shorting OTM at its expiry as the profits are less. However, you'll need to pay full margin of future contract to sell an option. So there's hardly much benefit of doing that. If you've such margin available handy, you can surely sell multiple lots and get all the premium to your pockets.
But, if the market reversal happens and the price moves from OTM to ITM, then there's much higher probability of you losing than winning.
