This chapter brings together the key findings of the book and reflects on the contribution of applying socio-technical systems theory to understanding and addressing the problem of crypto-laundering. It summarises how the models developed for the book explain both criminal adaptation and institutional response to the topic, based on the empirical analysis of crypto-related STRs in Ireland. The practical value of these models for regulators, FIUs, and the wider AML system is discussed, along with their applicability to other FATF-aligned jurisdictions and problem domains. The chapter also acknowledges and outlines the research's limitations. It proposes future research directions, including comparative FIU studies, STR lifecycle analysis, and introducing random blockchain sampling as a complementary stream of financial intelligence for analysis.
