From Echo to Kaito to Buidlpad, they basically cover the entire lifecycle of Crypto early-stage projects: 1. In terms of decentralization, Echo is fully permissionless, Kaito has light vetting, and Buidlpad operates with extreme scrutiny. 2. For profit potential, Echo relies on sharp judgment for big wins, Kaito is full of strategic games, while Buidlpad leverages brand power for stable returns. 3. Echo lacks marketing impact, Kaito can generate attention, and Buidlpad creates FOMO. These three platforms entered the public eye around late last year and early this year, marking a major innovation in the early-stage/VC space~
