Caution!
DO NOT USE VaultMEX EXCHANGE!
AVOID VAULTMEX EXCHANGE LIKE THE PLAGUE.
VaultMEX are scammers and thieves.
They will steal your BTC and your BCZ AND IF THEY GET YOUR BCZ, THEY DUMP IT ON CREX.
I used that in the past already. Doesn't look scammers to me imho, just a little exchange focused on anonimity and privacy.
