You can trade $SBD on HTX(Formerly, Huobi exchange) as well.
Unfortunately, Upbit exchange decided to delist SBD. For now, Upbit halted deposits of SBD, and they support only withdrawls of SBD.
However, HTX supports SBD trading. You can deposit and withdraw SBD on HTX. It's been a half year since listing SBD. I didn't know that.
You can sign up for HTX, using my referral link.
I hope SBD will be listed on other CEX(Centralized Exchange)es and DEX(Decentralized Exchange)es more 🙏
You can use swapter.io to change SBD
