vqo.in, ybx.in, mnq.in can be worth something in the future, once and if all the LLL.ins are taken, mi2.in and mi3.in undeveloped are worth reg fee imo.
The LLL.in names are worth reg fee, they are more of a long term hold for a few years to really get the benefit once all the LLL.in names have been sold. Your 3 character ones: mi2.in & mi3.in, can't really see much potential in those names.
The LLL.in you will need to hold on to for a little bit like others have said but the others ones I don't see much in. Reg fee for mi2 and mi3 and just a little over reg fee for the other ones at the current moment. Hold onto those LLL ones though!
