The primary way of communication with the Campaign Owner is always reading the newsletters, as the Campaign Owner announces new perks, developments, and other changes through them, which may be important from an investment standpoint.
In addition to the newsletter, the Campaign Owner regularly holds Investor Meetings, which are held as online video calls on Zoom, organized by TokePortal, and recordings of which are also published. During the Investor Meetings, Investors have the opportunity to ask questions to the Campaign Owner, making this generally the most direct way to communicate with the founders.
