It looks like they canceled all pending BTC transactions and moved their coins to a segwit wallet. https://blockchain.info/address/1CPg9Sc4AgABkz94AukSf9o8EeNruEZYp7

Hopefully they will still send my 50,475 satoshis that I withdrew 6 days ago. The pending tx appears to no longer be valid due to a doubke spend to their new wallet.
