Unique Venture Clubs is a non-custodial platform - you do not need to have a legal entity if you open a club for the purpose of trading digital assets on the secondary market. However, choosing to create a legal entity for your Venture Club has its benefits; it can enable a wider range of investments (i.e. startup equity, venture capital, etc.), help limit legal and financial liability for club members, be beneficial for filing taxes and allow off-chain activity like opening up bank accounts, using service providers, etc.
