Sold 1 Feb Nat Gas 5.00 Put for 2.13

I 1 Feb Nat Gas 5.00 Put for 2.13 (or $2130). I was initially looking to sell 5.25 for $3000ish, but I thought 5 would work even better even if it's less premium in terms of safety. I've seen NG moves $10K range in a day, so I don't know how safe it can be. Less than 2 weeks to go, I'll let his expire worthless or get assigned just like before.
