Cryptohub exchange was hacked and it will close operations soon.

All major coins have been affected. However they're refunding partial balances based on what coin you owned there, so check by logging in. There are some discrepancies in the information they provide though, for example their site says all WAVES were stolen while their Twitter says WAVES are safe.
