what will happen with the rest of the posw will they be able to still swap , burn or will it be continued to be traded
The PoSW that isn't swapped will be burnt. However, you can still swap your PoSW coins for XSN at
https://xsncoin.io/swap/ You have until May 1st to do so, after that the coins will be burned.
Did you manage to talk to Livecoin to allow POSW withdrawals so that we can swap for XSN at
https://xsncoin.io/swap/ ?
I have a lot of POSW stuck in Livecoin, I transferred them from Cryptopia on the recommendation of this Bitcointalk thread and now they are stuck.
