Though, for the record, that ranking’s off.” “I’m hosting a live AMA on Binance Square today at 9 PM (11 hours from now). Anyone’s welcome to ask questions—feel free to ask me anything.

**April 15th Update** Prediction market platform Polymarket has kicked off a review of third-party startups in its Builders Program, launched last November to let external developers build trading apps on its infrastructure. Some 200 developers have joined so far, eligible for up to $2.5 million in grants and weekly rewards—but a key issue has emerged: top participants in the program are all building copy-trading apps. These apps curate trading accounts with abnormally high win rates, flag suspicious timing/trade amounts, and let users copy trades with one click. Kreo’s selling point is helping users “spot insider traders faster than others,” while Polycool lists an “Insider Trading Guide for Polymarket” on its site, noting: “This isn’t the stock market—betting on non-public info won’t land you in jail; decentralized prediction markets have totally different rules.” The Builders Program has driven Polymarket’s trading volume from $100 million last November to over $600 million

He emphasized the regulation does not prohibit individuals or entities from holding crypto in overseas wallets — but they must report these holdings to the federal tax authority. The measure is scheduled to take effect in July, alongside the associated regulatory framework.
