According to The Block on June 1st, the decentralized exchange Binance DEX announced that it will implement a geographical blockade on users from 29 countries including the United States starting July 1. Trading and wallet access services through binance.org will no longer be available to users from IP addresses in these 29 countries. But by using a VPN or a compatible wallet that already supports local transactions, it is still possible to circumvent this obstacle. This cautious decision may be related to the US SEC's November allegation that the founder of the decentralized exchange EtherDelta operated an unregistered stock exchange. In theory, Binance cannot prevent anyone from issuing a securities token.
