Due to tokens being classified as securities, STOs are more susceptible to regulation and thus represent a more secure investment alternative than ICOs, which have been subject to numerous fraudulent schemes. Furthermore, since ICOs are not held in traditional exchanges, they can be a less expensive funding source for small and medium-sized companies when compared to an IPO.[6] An STO on a regulated stock exchange (referred to as a tokenized IPO) has the potential to deliver significant efficiencies and cost savings, however.
