KYC is bloody mandatory these days, mate, but it saves ya heaps of strife when ya wanna have a fair go against the pokies joint that's holding onto ya winnings. Normally, they don't hang onto ya dosh when ya strike it rich and wanna cash out. Once ya've already verified yaself, they don't hassle ya again. So, reckon KYC's a necessary annoyance, but worth it in the end.
