I guess this is my disconnect or naïveté, but I thought the whole point of crypto is that it’s fairly traceable - obviously, there’s no decentralized way to address fraud, but couldn’t we have a decentralized report system that can warn people before sending tokens to known malicious actors?
"Often" indicates that there are ways to send funds in a way that is not reversible. Wouldn't a thief make use of such a way?
"Often" word is used because it also covers the case of small transactions. As transactions get bigger, systems get slower. I have had personal phone calls from bank to ensure I wanted to send big sum of money.
