Your logic doesn't make sense. You thought it wouldn't have any value after the snapshot so you held in your wallet and forgot about it. So where exactly are you losing anything? Is it because you could've earned a bit by selling after the snapshot which you didn't? Thats not a loss, more like some gains you've missed.
This was not like a snapshot for a new DAC where people were getting in and out of PTS because they knew price would spike before the snapshot and drop after it. This was a snapshot where all shares(PTS, AGS, BTSX, DNS etc.) would be combined into BTS. So how or why would any logic dictate that after this snapshot that any or all of them would still exist and be traded? They should all be worthless as they don't exist anymore. Only BTS does. BTW a gain I missed is exactly equal to a loss. Its called a lost opportunity and that opportunity was lost because only the few people truly in the know, knew exactly what was happening. I most certainly would have dumped every PTS and BTSX I had if i had even an inkling of a clue that I was supposed to. I sure as hell bet you did.
