Cryptopia shows a message on their website stating they are going into liquidation.

Two days ago I deposited a small BTC amount and opened an order to buy some Bullion

When we see Bullion getting dumped at Crex24, it's probably from Cryptopia...
I do not think "Bullion (CBX) 'the Digital Precious Metal" lost its price for cryptopia hence I think "Bullion (CBX) 'the Digital Precious Metal" lost their price as they have no option to deposit on any good exchange.
