From Endgadget:
Some of those involved in the exchange hired Hanekom Attorneys, the law firm that said it couldn’t find the two brothers, to investigate the incident. It found that someone had withdrawn Africrypt’s pooled funds from the local accounts and client wallets where the coins were stored originally and put them through tumblers and mixers, making it difficult (though not impossible) to trace the money. “Africrypt employees lost access to the back-end platforms seven days before the alleged hack,” the law firm told Bloomberg. The outlet attempted to call both Cajee brothers multiple times only to get their voicemail each time.
Complicating any recovery attempt is that South Africa’s Finance Sector Conduct Authority can’t launch a formal investigation into the incident because cryptocurrency isn’t legally considered a financial product in the country. If no one can recover the money, it will go down as the largest cryptocurrency loss in history, easily overshadowing the approximately $200 million CAD that disappeared when the founder of Canada’s QuadrigaCX exchange died while travelling in India.
While this is bad news for the crypto industry, it is nothing unusual about it. Is this the first time this is happening? Not! Well, since such cases have already happened, it means they will continue, it's another matter that there are no tools to solve this problem. Of course, all this is related to anonymity, etc., but the fact of the matter is that if you want to have protection and a guarantee, then you need to choose sites with work experience and proven organizers, and then this also does not 100% grant you the preservation of your funds. Moreover, we are talking about BTC, which means that someone just decided to withdraw these funds for themselves. We are unlikely to find out who did this, but we always need to know and remember that this can happen with any crypto exchange.
