So far here's what I think I understand has happened while I was gone:
Protoshares -> Protoshares PTS -> Bitshares PTS -> Bitshares <- Bitshares X
Voting snapshot, DNS snapshot, Gaming snapshot, Music snapshot
Price way up -> Price way, way down
Supply slowly burning -> Supply suddenly grows, something about a merger?

What is most crucial for me is to at least understand are these two main points:
1) What changes took place in protocol(s) and what is the future of Bitshares/PTS?
2) What happened to my shares? Do I deserve any new shares? If so, how do I claim them and my snapshot shares?
I only have access to old skool wallet.dat file and its keys.

Save your finger dexterity if there are links that already fully explain that.

Thank you thank you so much for taking your time to help me get back in the loop
