You can trade in Bitmart as a US citizen through the link

I have a BSV coin and I'd like to sell it. Unfortunately it is delisted on KuCoin and I live in the US. Seems like there aren't many exchanges US friendly that will accept it.
So what do you want right now?
Do you want to use a third party to exchange the coin for you?
If that is your intention, then you will need to include some other info such as, the coinyname and which exchange their listed, from that point anyone who is willing to help you out can reach out to you and make an offer and better still you post it on exchange board.

I think his major challenge is where to sell considering the country he resides which is US that have restrictions on several exchanges. As BSV have been delisted from Kucoin and Coinbase, it becomes a problem for most US traders so the fastest approach may be to use the link you posted in the exchange section where any reputable member from another country can sell for him because the coin is still listed in many exchanges.
