Minters Dev, a blockchain game developer, has announced its closure, leading to the shutdown of its game 'Battle for Blockchain' within 30 days. Despite attracting over 700 daily active users and achieving a 48% 7-day retention rate, the company faced insurmountable challenges including funding shortages, technical issues, and intense market competition. The founder cited the excessive growth of automated activities in the game, which resulted in user attrition and declining token prices, as key factors in the decision to cease operations.
