Banking Ombudsman Nicola Sladden says many victims are thoroughly convinced the crypto scammers are legitimate dealers.
The same happens with romance scammers, who think they've met their future life partner, who just happens to need some money transferred to them.
Janine Grainger, chief executive of New Zealand-based broker Easy Crypto, says scammers will convince their victims not to tell the bank what they are doing with the money.
"[Victims] are coached by scammers to lie. The most recent excuse I heard was 'if you tell your bank about this transaction, then your bank will try to discourage you from doing it because they want the commission and they want you to do the deal with us'.
"To be fair, I think the banks do a very good job of trying to stop people," says Grainger.
It's a difficult one because people should have agency and be the arbitrator of what they can do with their own money, she says. "They should also have the education and scepticism to be making good decisions and not being caught with scams."
Always check the legitimacy of any crypto platforms. Another case Sladden investigated involved a New Zealander who transferred funds to what appeared to be a New Zealand-based crypto trading platform. It was fake, a fact he could have discovered that by googling.
My experience is that new crypto investors sometimes think they're smarter than the average person. But even smart people can get caught up in scams.
Grainger is often contacted by people who have been caught in scams. As with traditional scams, once someone is caught, scammers have their contact details and will try again and again.
"They'll try to trick you with every scam in the book. One of the really common ones that we see is a recovery scam, where [victims are led to believe] this company overseas can help get it back." The victim is told they just need $10,000 or another figure to 'pay the tax' to recover their money. "Victims are vulnerable and susceptible to psychological manipulation."
While it's commonly thought that stolen crypto can't be recovered, courts in Britain and the United States have recently allowed scam victims to serve documents over the Blockchain, effectively freezing stolen crypto that had been tracked down. Those victims had lost millions and had money to pay crypto hunters to track down the funds and lawyers. They have in part recovered their money. It's unlikely the growing number of scammed Kiwi are going to be in that position any time soon.
