It is the part 2 post for process of ICO vs STO.
ICOs are meant for raising funds in an unregulated environment. In contrast, STOs are launched with regulatory governance in mind. Hence, it is way easier to launch an ICO than STO. STO requires a company to do a lot of upfront compliance work. While everyone can launch and participate in an ICO, only entirely regulatory compliant companies and accredited or at least known investors can sell and purchase security tokens(STO).
