Initial Coin Offering (Token Generation Event) in Liechtenstein as a method of crowdfunding in or through Liechtenstein does not require a license per se.
But an official authorization or approval by the competent authority (Liechtenstein Financial Market Authority, FMA) must be obtained. FMA’s fact sheets on ICO’s.
Moreover, the FMA, like the Swiss financial market authority FINMA in its ICO guidelines differentiates between utility tokens such as those granting access to software and security tokens which are similar to traditional securities. The latter are subject to financial markets statutes.
Utility Token Offering will not require a license.
Security Token Offering will most likely require publication of a prospectus and possibly dealer licenses will need to be obtained.
Before launching your ICO you should get an overview of the relevant FMA requirements
for your token, company structure, tax, migration, and other issues, and take these into account.
