The Betoken fund runs in investment cycles, and at the start of each cycle there are 3 days where investors can deposit & withdraw their funds: the Intermission phase. Redemptions are available each 27 days in the Betoken Fund. Redemptions incur no withdrawal fee.
A countdown is displayed at the top of the Investors portal on desktop and in the menu on mobile, to indicate when Betoken accepts new capital connections. It's happening every 27 days during a 3-day period.
