Binance DEX, a non-custodial exchange which launched in April, announced to its users that it will start geo-blocking 29 countries including the USA starting from July 1. Trading and accessing wallets through binance.org will no longer be available to users with IP addresses from the affected countries. It will still be possible to circumvent the block by using a VPN or by using one of the compatible wallets that already support native trading.
The caution could be connected to the SEC charging the founder of decentralized exchange EtherDelta with operating an unregistered securities exchange in November. Binance theoretically could not prevent anyone from issuing a security token.
