If they were triple or double premiums then yes dropping them was probably a bad idea. Reseller price on forums for LLL.ins are pretty decent so worse case scenario you could have made a few $$ on the reseller market instead of dropping. I would definitely recommend keeping any other triple or double premiums that you have, or list them here for sale as they will get snapped up. LLL.ins have a very bright future in my opinion.
I alos think LLL.in have potential. But for some time not long ago many LLL.in were available and it looked like this will saty so. Then I dropped. Later one week they almost all vanished. Seems someone put some 600$ or so to buy out all. If he/she sells at least 1/year at some 1000$ it was a good business.
