Is PWC killed? I just sync'd my PWC wallet, and it is in sync with 29945 blocks downloaded, there's no issues at all. All my previous transactions are there, and balance is intact.
So it does not look to be that it is killed.
If you don't mind the fact that now one guy has more then half of all PWC coins and thus can crash any exchange market at any time for as far in the future as you could imagine- then by all means. Enjoy.
Anyway, it is not killed, no records/transactions are altered, all balances are fine, and you see the blocks are increasing at about the block time, meaning people are still mining it. No sign at all it is killed.
