@JHWeissmann The option of irreversible payment allows some sales to proceed that would otherwise simply not. Is this a social good given the risk that customers in other cases would be dealing with a scammer? I don't know, but in specific cases, it is certainly value-add.
@JHWeissmann不可逆付款的选择允许一些销售继续进行，否则根本不会进行。考虑到客户在其他情况下与骗子打交道的风险，这是一种社会利益吗？我不知道，但在特定情况下，这肯定是增值。
