To avoid such scams with the FTX exchange, you need to prohibit the exchange from managing client deposits. For this violation 1,000,000 life sentences. I used to be an anarchist too, but today everyone understands that cryptocurrency exchanges should be under the control of regulators.
They don't need to be under the control of regulators, but for sure they need to have some proof of reserves. SBF used the client's deposits for his own projects (reserves were in FTT) and with the collapse of FTT he literally ended up with nothing.
Answer the question, why did all 4 of the world's largest auditors refuse to work with crypto exchanges?
But because the SEC said that they will be very painful to beat on the ass.
Maybe it's better to spend energy on fighting fraud?
