Is this the first Aussie exchange exit scam? I can't recall any (I could be mistaken), but if this is then it could be big blow to Australia crypto enthusiast as we all know that they country is big as far as crypto is concern.
I know of Australian exchanges that have been shut down by the authorities, but not of any that performed an exit scam. I think this might be due to the fact that a lot of services in Australia are very small services where you can buy and sell coins from and to the service, and not like an exchange sell into an orderbook.
If a small service performs an exit scam, it's less likely to be covered by news outlets unless some crappy news outlet bot auto copy and release the news it found somewhere on a site.
In the end, scams and hacks haven't ever really caused a problem to any crypto ecosystem. Where one exchange goes down, multiple pop up trying to take over that market share.
