According to @CryptoKing_2020, Sigma Token is running a Browse & Earn campaign where users earn token rewards by completing tasks inside the Sigma AI Browser, which is described as a private AI browser (source: @CryptoKing_2020 on X, Jan 8, 2026). According to @CryptoKing_2020, new users who download via a referral link receive 500 tokens instantly, with additional earnings available through daily and weekly quests, and the post instructs participants to repost the announcement and follow @Sigma_Browser (source: @CryptoKing_2020 on X, Jan 8, 2026). According to @CryptoKing_2020, the announcement states all participants are winners, framing the distribution as engagement-based rewards rather than a token sale, and the post does not provide details on listings, transferability, or blockchain specifics (source: @CryptoKing_2020 on X, Jan 8, 2026).
