Replying to @token2049
@token2049 was an amazing experience 🇸🇬 We connected with many potential partners, from @circle to @etherfuse @SuiNetwork , and @CantonNetwork , caught up with old friends from @EasyMM_official , and wrapped things up by presenting Nysa to a large audience at the @BitAngels event. A big thank you to everyone we met along the way! Next stop: Lugano — Plan ₿! 🇨🇭

If you tokenize assets on-chain, you need more than that. You need adoption, use cases, liquidity and revenues around your assets. Introducing MaaS — Market-as-a-Service: a structured pipeline to build, launch and distribute credit markets around your assets. Read more 🧵

Milo web just launched. Improved analytics, directly synced with mobile. milo-sports.app

Stel een doel — Milo bouwt de weg ernaartoe

Milo maakt van elke set, hardloopsessie, maaltijd en nacht slaap een trainingsplan dat week na week meebeweegt, met een AI-coach die het bewijs achter elke keuze laat zien.

Transferred my workflow into an AI skill and it’s really OP! Transfer any feature request into a TDD implementation plan with each phase as a hard deliverable. Implement each phase using an execution loop. It’s really good! github.com/JordyKingz/jordyk…

every 2 weeks: weigh in. Milo compares it against your logged training and intake, then sends back a progress report.

currently working on Milo being an actual coach - multi-week strength plans that refuse targets you can't reach - weekly check-in that explains what it changed and why - talk to it, get a proposed change, confirm it more soon
