I did a little research on this and found that 2 Goals Up Early Payout is available at several crypto sportsbooks besides Stake.
Shuffle offers an early payout if a team is ahead by 2 goals in the 1x2 (2UP) market. According to their information, this market is available in more than 40 leagues.
Shuffle 2 Goals Up Early PayoutRollbit includes La Liga, Bundesliga, Serie A, Ligue 1, Europa League, Conference League, Brasileiro Serie A, Argentina Primera Division, Copa Libertadores and Copa Sudamericana in addition to the Premier League and Champions League.
Rollbit 2 Up Early PayoutBetfury also has a similar promo. According to their terms, the Champions League, Europa League, Conference League, Premier League, LaLiga, Bundesliga, Serie A, Ligue 1 and Brasileiro Serie A are covered by this offer.
