A Sender Controlled Media (SCM) platform user is presented incentives for performing rewardable platform activities that result in accruing points in a user-specific account from which points can be redeemed by transfer or cryptocurrency conversion to an external user-designated wallet. A reward received for each instance of a rewardable platform activity is determined based on a range of platform context including a target average points payout, an aggregated total points payout over a distribution period, and a type of rewardable platform activity.
