This paper investigates the relationship between an individual's saving and borrowing practices and his/her propensity to use fintech services. More particularly, we examine whether having multiple saving and borrowing channels increases a person's likelihood to participate in online funding platforms, and use robo-advisors. Using a sample of over 2000 respondents to a survey we conducted in Malaysia, our main results indicate that individuals who save and borrow via multiple channels, and through external conduits, are more likely to use fintech services than their counterparts. This is consistent with the view that individuals who use multiple saving and borrowing conduits are more likely to perform mental accounting, a concept which is commonly used by fintech companies to facilitate personal wealth management. Further, our findings reveal that among respondents with multiple saving channels, those who put less importance on trust in financial products, and consider financial returns essential, are the most likely users of fintech services. Overall, our findings offer new insights by providing a better understanding of the factors that foster the use of fintech services
