Having worked in those environments, the audit provisions mean it's all very much simpler (though not simple) to trace in conventional bank account land.
The relative obscurity of the blockchain acts in the crim's favour, though depending on the choice of crypto format traceability is not beyond wit of man. No doubt for such a theft the perps will attempt to cycle the proceeds through a bunch of smaller transactions and obfuscations to try and hide the (eventual) points of sale.
Fiat currency, backed by government policies and the law; versus Crypto backed by vagaries. (And, this is why actual assets have an edge over the intangible).
You can find faults with both systems. You pays your money, you takes your choice!
