Kucoin USA users: I was just now able to sell and withdraw by using a free trial of NordVPN to change my ip address to Singapore, and by using the app "Fake GPS location" to also change my gps to Singapore

It took 25 minutes for the usdt to show up in my kraken account. I had to use the Ethereum ERC20 network. At the end of the process kucoin tried to text me a verification code but I didn't get it, but there is the option of a code by phone call which I did get. Be sure to cancel NordVPN before the free seven days are over, and the fake GPS app I used on android is called "Fake GPS location".

Maybe you don't have to change it to Singapore, maybe you don't have to change the GPS, I'm not sure. This is just what worked for me.
